1.0 INTRODUCTION
1.1 BACKGROUND
       A "Request for Emissions Testing at Four Asphalt Roofing and Processing Facilities"
was submitted by the U.S. EPA Emission Standards Division (BSD), Minerals and Inorganic
Chemicals Group (MICG) to the Emission Measurement Center (EMC). The Emission
Measurement Center directed Midwest Research Institute (MRI) to conduct emissions testing at
asphalt roofing plants. This report presents results of MRI's FTIR and Method 25A testing
conducted at U. S. Intec in Port Arthur, Texas. The field measurements were performed in
September 1997 under several test conditions for both controlled and uncontrolled emissions.
1.2 PROJECT SUMMARY
       The purpose of this test program was to obtain uncontrolled and controlled HAP
emissions data from asphalt roofing and processing plants to support a national emission
standard for hazardous air pollutants.  Specifically, the objective was to measure HAPs in several
processes. An additional goal was to measure other compounds that could be detected with the
FTIR system.
       Emissions were measured at both the inlet and outlet of the incinerator (thermal oxidizer)
used to control emissions from mixing and holding tanks. Additionally, uncontrolled emissions
from individual mixing and holding tanks and coaters were  measured. A total of eight sampling
locations were tested, noted as El through E8 in Table 1. Midwest Research conducted FTIR
testing using EPA Method 320, and hydrocarbon testing using EPA Method 25A. Eastern
Research Group, Inc. (ERG) performed manual methods at  the thermal oxidizer inlet and outlet.
Table 1 shows the test matrix and summarizes the tests performed for MRI's portion of the field
testing.
       Three test runs were conducted by alternating sampling at the inlet and outlet of the
thermal oxidizer. The sampling time for the FTIR and THC methods (approximately 4 hr per
run) coincided with ERG's manual sampling periods.
       Similarly, the two coater vents (roof stacks) for both the SBS and APP product lines were
tested during three separate runs each (approximately 1 hr each). Finally, one test run each
(approximately 1 hr) was conducted on both the holding and mixing tanks for both the APP and
SBS product lines.

2.0 PROCESS DESCRIPTION AND TEST LOCATIONS
       The U.S. Intec facility in Port Arthur, Texas, was selected as a test site representative of
the modified bitumen production process in the asphalt roofing industry. The site uses the
modified bitumen process using atactic polypropylene (APP) or styrene-butadiene-styrene (SBS).
2.1 PROCESS DESCRIPTION
       The facility produces rolled roofing products by saturating a polyester substrate and a
fiberglass substrate with modified bitumen in two separate production lines(APP or SBS). A
flow diagram of the process is included in Figures 1 and 2. Sampling points, as noted earlier in
Table 1, are designated as El through E8. Both the APP and SBS substrates enter their
respective production lines through a web unwind stand and then go through a dry looper.
Asphalt is unloaded from tanker trucks into two 100-ton, 350°F asphalt storage tanks. Asphalt
from the storage tanks is distributed to six 10.5-ton, 400°F mixing tanks for the production line
using polyester substrate and two 10.5-ton, 390°F mixing tanks for the production line using
fiberglass substrate. Tanker trucks also unload polymer liquid into two steam-jacket storage
tanks.
       Modified bitumen is produced by combining the asphalt with polypropylene and fillers in
the six mixing tanks for the line using polyester substrate.  Modified bitumen is produced for the
line using fiberglass substrate by combining asphalt with SBS in one mixing tank and fillers in
the second mixing tank. The modified bitumen in the mixing tanks is transferred to two holding
tanks for the line using polyester substrate and one holding tank for the line using fiberglass
substrate before going to the respective coaters. The coaters are impregnation vats where the
substrates are saturated with the modified bitumen. Once the saturated polyester substrate leaves
the vat, it is coated with granules and talc.  The saturated fiberglass substrate is coated with
granules and sand. After both products are cooled, they go through separate finish loopers and
roll winders.
       The facility operates 24 hr per day from Monday morning through Friday evening (5 days
per week).
2.2 CONTROL EQUIPMENT DESCRIPTION
       Emissions from the holding and mixing tanks for both SBS and APP production lines are
ducted to the thermal oxidizer. The gas stream passes through a booster fan to a cyclone

separator where coarse paniculate matter is removed. The thermal oxidizer operated at a
temperature of 1400°F and a residence time of 0.5 seconds. Gas was moved from the thermal
oxidizer to the slack by an induced draft fan where gas temperatures were approximately 480°F,
at a nominal flow rate of 10,000 acfm (23.6 ft/sec velocity).
       Emissions from holding and mixing tanks were not controlled at the locations tested, and
the coalers are not controlled, but vent to the atmosphere. Gas stream temperatures from the
mixing and holding tank outlet ducts ranged from 110° to 316°F at pressures slightly less than
atmospheric pressure.  Velocity heads in these ducts were very low and required measurement
with a hot wire anemometer.  Gas streams in the coater vent stacks had temperatures of approxi-
mately 90° to 110 °F and pressures above atmospheric pressure (an in of water or more).
Velocity heads in these ducts were approximately 0.60 in of water, or greater.
       The water vapor content at all sampling locations except the thermal oxidizer outlet stack
was close to ambient conditions. The water vapor content in the thermal oxidizer outlet stack
was approximately 4 percent to 7 percent by volume.
2.3 SAMPLING AND MONITORING LOCATIONS
       Sampling was conducted at a total of 8 different locations, noted previously as locations
El through E8 in Table 1 and Figures 1 and 2. Each of the following sections briefly describes
the sampling locations in greater detail. Sections 2.3.1 and 2.3.2 describe the inlet and outlet
locations for the thermal oxidizer, which is fed via a common duct. Sections 2.3.3 and 2.3.4
describe exhaust ducts from the individual holding tanks which feed into the common duct.
Sections 2.3.5 and 2.3.6 describe exhaust ducts from the individual mixing tanks which  feed into
the common duct. Sections 2.3.7 and 2.3.8 describe ve.nt stacks for the coating processes, which
are not part of the thermal oxidizer treatment system.
2.3.1 Thermal Oxidizer Inlet Duct (El)
       Thermal oxidizer inlet sampling was conducted in the common manifold (header) which
collects emissions exhausted from the mixing and holding tanks from both production lines. A
schematic drawing of the inlet sampling location is presented in Figure 3.  Two 4-in ports
(nipples), 90° apart, were installed in cross-section (CS) 2 of the horizontal, circular, steel duct
for ERG's sampling and velocity traverses. A 3-in port (nipple) was installed in CS1 for the
Method 25A and 320 (FTIR) single-point sampling. Temporary scaffolding for access from the

-------
ground to the location was installed. Approximately 150 ft of sample transfer line from the
trailer was required here.
2.3.2 ThermaTOxidizer Outlet Stack (E2)
       Thermal oxidizer outlet sampling was conducted in the stack immediately downstream of
the thermal oxidizer.  The outlet sampling location, approximately 30 ft above ground level, is
also presented in Figure 3. The two existing 3-in ports, 90° apart, in CS4 of the circular, steel
stack were replaced with 4-in nipples and were used for ERG's sampling and velocity traverses.
A 3-in port (nipple) was installed in CS3 for the Method 25A and 320 (FTIR) single-point
sampling. Approximately 200 ft of sample transfer line from the trailer was required here.
2.3.3 Modified Bitumen Holding Tank Exhaust Outlet E19B (E3)
       This sampling location is in a horizontal run of 10-in diameter steel duct (E19B)
exhausting emissions from SBS production line holding tank No. H3. One 3-in port was
installed on the side of the duct at a location directly over holding tank No. HI. The duct is
approximately 30 ft above the production room floor, just below the roof. The top of the tank is
accessible by stairs from the production room floor and a walkway. Approximately 200 ft of
sample transfer line from the trailer were required here. Only one diameter was traversed for
volumetric flow rate measurements because velocities were very low and stratification across the
gas stream was insignificant. Appendix A contains traverse point information and a sketch of the
sampling port arrangement for this location.
2.3.4 Modified Bitumen Holding Tank Exhaust Outlet E1B CEA)
       This sampling location was a vertical section of 8-in diameter black iron pipe (E1B)
exhausting emissions from APP production line holding tank No. HI. The duct was right off the
top of the tank and was accessible from a permanent platform on top of the tank.  One 3-in port
was installed on the side of the duct at a location such that the sampling equipment was just
outside of the handrails and supported from an overhead beam. This location was approximately
20 ft above the production room floor and accessible by stairs from the  production room floor
and a walkway. Approximately 200 ft of sample transfer line from the  trailer were required here.
Again, only one diameter was traversed for volumetric flow rate measurements because
velocities were very low and stratification across the gas stream was insignificant. Appendix A

       This sampling location was a horizontal section of 8-in diameter steel duct (E17B)
exhausting emissions from SBS production line mixing tank No. M7. The duct was
approximately 12 ft above floor level. This floor level was accessible by stairs from the ground
level. One 3-in port was installed on the side of the duct. Approximately 100 ft of sample
transfer line from the trailer was required here. Only one diameter was traversed for volumetric
flow rate measurements because velocities were very low and stratification across the gas stream
was insignificant. Appendix A contains traverse point information and a sketch of the sampling

approximately 10 ft above floor level. This location was above the production room floor and
was accessible by stairs from the production room floor and a walkway. One 3-in port was
installed on the side of the duct. Approximately 200 ft of sample transfer line from the trailer
were required here.  Only one diameter was traversed  for volumetric flow rate measurements
because velocities were very low and stratification across the gas stream was insignificant.

       This sampling location was a vertical, 29-in I.D. steel duct or "stack" (E10S) exhausting
emissions from APP coater vat No. L3. The duct was located on the slanted, metal sheet roof
(closest stack to the access ladder up the side of the building). Two 2-in ports, 90° apart, were
about 5 ft above the roof. These ports were replaced with 4-in ports (nipples) for ERG's
sampling and velocity traverses. Another 4-in port was installed 1 ft below and offset 45° from
the other ports for the Method 25A and 320 (FTIR) single-point sampling. Approximately 200 ft
of sample transfer line from the trailer were required here. Appendix A contains traverse point
information and a sketch of the sampling port arrangement for this location.

3.0 RESULTS

3.1 SCHEDULE

       Testing of the U.S. Intec, Inc. facility in Port Arthur, Texas, was performed from

September 22-26,1997. Table 1 summarizes the schedule and the specific tests performed.

Sampling logs and notes for the Method 25A (THC) and Method 320 (FTIR) sampling are

contained in Appendix D.  The THC and FTIR sampling was performed in coordination with the
manual sampling conducted by ERG.

3.2 FIELD TEST PROBLEMS AND CHANGES

       Several deviations from the Test Plan were performed to adapt to field conditions. The
following is a summary of these changes.

  1.  Difficulties with one of the THC analyzers prevented the simultaneous operation of both
     analyzers. Therefore, inlet/Outlet testing of the thermal oxidizer was accomplished by
     sampling in alternating 30-min intervals at either location using a single THC analyzer. In
     order to provide a parallel data set, the FTIR sampled the same location as the single THC
     analyzer, and alternated between locations on the same 30-min schedule.
  2.  An additional problem with the THC data logging system necessitated manual data logging
     during Run 1. For all of the remaining tests a computerized data logger was used.
  3.  At the request of EPA representatives on site, the 2-hr sampling period for the inlet/outlet
     testing of the thermal oxidizer was extended to 4hrs.  All three of the thermal oxidizer tests
     were 4 hr.
  4.  Due to sampling error, ambient air was drawn into the sampling system during Run 1 on
     the APP Holding Tank 1. This test was repeated and no 25 A analysis of the Run 1 APP
     Holding Tank 1 data was performed.
  5.  During the final test, Run 2 on the APP Holding Tank 1, paniculate buildup in the sampling
     lines caused failure of the heated pumps. As  a consequence, the FTIR sampling was
     changed from continuous spectral collection to batch collection, and was performed
     manually. For each batch sample, the cell was flushed twice with dry nitrogen, evacuated,
     then filled with sample gas.
  6.  Absorbance bands were much greater than 1 in the analytical region near 2900 cm"1 in
     some  spectra from Run  1 at the APP mixing tank and Run 2 at the APP holding tank.  At
     these locations some spectra of diluted samples were recorded to bring the entire spectrum
     on-scale. The dilution procedure involved removing some sample from the gas cell, noting
     the sample pressure and then filling the cell with dry nitrogen to ambient pressure.  The
     spectrum of the static, diluted sample was then recorded.  The readings from the Barocell
     pressure gauge were used to determine an approximate a dilution ratio.  The dilution ratios
     were included in the concentration calculations.
  7.  Samples were spiked in two different ways. For the first day, a blended gas containing both
     SF6 and a volatile target compound was not available, requiring two separate gases to be
     blended through two mass flow controllers and then spiked into the sample lines.  Spiking
     after the first day was performed using a single blended gas containing both SF6 and

                                          12

-------
    p-xylene as the target volatile organic. Since all locations were spiked with the p-
    xylene/SF6 mixture, these results are reported in the spike summary.
 8.  Because of concern about interference from high CO2 concentrations, the analyte spike of
    the p-xylene gas standard was controlled at a flow rate of approximately 2.0 Lpm with a
    dilution ratio of about 5:1. Much lower spike flow rates were used at the coater roof stacks.
 9.  Due to time restrictions in coordinating testing with ongoing plant operations, spiking
    during the first four sampling days was performed in duplicate, rather than in triplicate.
    Triplicate spiking was performed on the last day.
10.  Spectra collected during the last two days occasionally contained especially high
    concentrations of hydrocarbon species. Some of the hydrocarbons may have adhered to the
    cell walls in subsequent samples, but this had little or no effect on the analytical results.
    Some additional nitrogen background spectra were recorded to minimize this effect.
11.  A second post-run CTS spectrum was not recorded on 9/22/97.  However, the Initial CTS
    spectra from 9/22/97 and 9/23/97 past the method criteria. Therefore, the first CTS
    spectrum on 9/23 also serves as the post-run CTS for the run on 9/22/97. The average
    deviation of all the CTS measurements from their average value was 2.8 percent.
12.  The FTIR cell did not pass the vacuum leak check during the field test (leak <4 percent of
    cell volume according to the EPA protocol). Gas was sampled continuously, whenever
    practical, to avoid diluting the sample When continuous sampling was not practical, the
    cell was filled above ambient pressure and the sample spectrum was recorded when the cell
     pressure reached equilibrium. A leak would result in a low bias in the reported
    concentrations, but the sampling procedures used should have minimized any effect on the
     results.

3.3.1 Thermal Oxidizer Inlet and Outlet
       The results for the thermal oxidizer inlet and outlet are presented in Tables E-l and E-2,
respectively. Compound identifications and their concentrations result from a least-squares fit
performed by the analytical program, using the available input data, which determined the best
linear combination from the reference spectra in Section 4.5.1.  The infrared absorbance near
3,000 cm"1 is primarily due to non-aromatic organic species. But the presence of cumene is
consistent with the spectra because its strongest absorbance in this region is from the aliphatic
hydrogens not  from the aromatic (bonded to the ring) hydrogens.  In the C-H stretching region
(near 2,900 cm"1), hexane and trimethylpentane give the best fit of the organic HAPs included in
the analysis.
3.3.2 APP and SBS Coaters
       Emissions from the coater roof stacks were much lower compared to the other test
locations. Table 4 presents results of uncertainty calculations for some HAP compounds. The
results for the APP and SBS coater stacks are presented in Tables E-3 and E-4.
3.3.3 APP and SBS Mixing Tanks
       Results from the APP and SBS mixing tanks are  presented in Tables E-5 and E-6. Both
locations exhibited high organic emissions.  Portions of the spectra from the APP mixing tank
were off scale  and could not be quantified. Some compounds could not be measured because no
quantitative reference spectra are available.  These compounds are not included in Tables E-5
and E-6. These other emissions include propylene and isomers of pentene.  These emissions
could be quantified if quantitative reference spectra of each compound were first measured in the
laboratory. The additional reference spectra could then be included in the analytical computer
program. Table 5 shows some additional compounds that may be included in the emissions, but
cannot be measured because there are no quantitative reference spectra available.
3.3.4 APP and SBS Holding Tanks
       Results from the APP and SBS holding tanks are presented in Tables E-7 and E-8.
Significant organic emissions, carbonyl sulfide, CO and ammonia were detected at each location.
Some compounds are identified in Tables E-7 and E-8.  Additional  organic  compounds that were
not measured may include propylene and pentene compounds.

3.3.5  Results from Spiked Samples
       Some samples were spiked with a controlled flow containing a mixture of p-xylene and
SF6. The SF6 was used to determine the spike dilution factor. The SF6 andp-xylene concen-
trations were determined with the same analysis program that was used for the other analyses.
The spike results are summarized in Table 6. Explanations of the calculations are given in the
footnotes to Table 6 and in Section 4.4.
       Two spike recoveries are presented in Table 6. The recoveries in column A result from
using the p-xylene reference spectra in the EPA  spectral library. Spectra of the p-xylene cylinder
standard disagree with the EPA library spectra by about 25 percent. These spectra give the
recovery  results shown  in column B of Table 6. In this test the spike recoveries fall within the
requirement of ±30 percent whichever reference data set is used.
       The discrepancy between the library spectra and the spectra of the cylinder standard is
illustrated in Table 7. This table compares the integrated absorbance band areas for the spectra
after correction for differences in temperature and pathlength.  The same table also compares the
spectra based on their accepted concentrations after correction for differences in temperature and
path length. Ideally the two comparisons would agree. In this case they differ by a bout
25 percent. The results from the analytical program depend on the abosorbance values of the
reference spectra so this discrepancy affects the  analytical results. This observation is compound
dependent and nothing can be inferred about the reported results for other compounds.

3.4 METHOD 25A RESULTS
       THC results as detennined by EPA Method 25A are presented in Tables 8 to 10.
Appendix B contains the raw data and graphical displays of the data versus time.
       As shown in Table 8, THC emissions from the outlet of the thermal oxidizer averaged
near 2 ppm as propane (wet). Run 1 emissions were the highest of the three runs, but were
collected by manually logging the data. The Run I manual readings likely introduced a high bias,
since all the readings fell near the extreme low end (zero point) of the instruments scale, 0 to
1,000 ppm as propane. Runs 2 and 3 were electronically logged and are believed to be more
accurate.
       The THC concentrations at the inlet to the thermal oxidizer ranged from 60 to 100 ppm as
>
propane (wet), with an average concentration of about 75 ppm. Concentrations were fairly
stable, with an occasional spike of 5 to 10 ppm above the average being observed.  Only once
was a spike greater than 10 ppm above the average observed.
       Mass emission rates of THC (in carbon equivalents) ranged from 3.1 to 3.5 Ib/hr (Thermal
Oxidizer Inlet) to 0.0043 to 0.0086 Ib/hr (Thermal Oxidizer Outlet). The calculated mass
emission rate of 0.279 Ib/hr for Run 1 of the Thermal Oxidizer Outlet is nearly two orders of
magnitude greater than either Runs 2 or 3, and further reinforces the believed inaccuracy of the
manually logged data.  Calculation of combusion efficiency, which is typically >99 percent for
these types of combustion systems, also shows that Run 1 does not agree with Runs 2 and 3, and
falls well below the expected 99 percent.
       An examination of THC emissions from the SBS and APP Mixing and Holding Tanks
(Table 9) shows that the APP line had much higher THC concentrations than the SBS line. For all
the mixing and holding tanks tested, APP Mixing Tank 1 had the highest THC concentrations,
and saw levels of 1,250 to 2,100 ppm. The APP Holding Tank 1 was next highest (475 to
875 ppm), followed by the SBS Mixing and Holding tanks, respectively (125 to 300 ppm).
       In terms of THC mass emissions (in carbon equivalents), the APP line was also
significantly greater than the SBS line. Due to the high concentration at a relatively high flowrate,
APP Holding Tank 1 emissions were the greatest by nearly an order of magnitude (0.4 Ib/hr).
APP Mixing Tank 1, on the other hand, had a quite low flowrate, but with the highest THC

concentrations still produced the second-highest emission rate (0.069 Ib/hr). The SBS mixing and
holding tanks showed the lowest emissions at 0.034 and 0.037 Ib/hr, respectively.
       As shown in Table 10, the SBS and APP coater roof stacks tested both had average THC
concentrations near 10 ppm. Both processes experienced some spikes of up to about 25 ppm and
also saw minimum concentrations fall below 5 ppm. Emission rates for the APP Coater Roof
Stack ranged from 0.54 to 0.79 Ib/hr. For the SBS Coater Roof Stack, emissions ranged from
0.29 to 1.1 Ib/hr. Run 1 emissions were three to four times greater than those observed in Runs 2
and 3, which showed essentially similar trends.

4.0 TEST PROCEDURES
       The procedures used for this field test are described in EPA Method 320 for using FTIR
spectroscopy taLmeasure HAP, the EPA Protocol for extractive FTIR testing at industrial point
sources and EPA Method 25A for total gaseous organics.  The objectives of the field test were to
use the FTIR method to measure emissions from the processes, screen for HAP using the EPA
FTIR reference spectrum library, and analyze the spectra for compounds not in the EPA library.
Concentrations were reported for compounds that could be measured with FTIR reference
spectra. Additionally, manual measurements of gas temperature, gas velocities, moisture, CO2,
and O2 by ERG and MRI were used to calculate the mass emissions rates.
       Midwest Research Institute used the extractive sampling system shown in Figure 4 to
transport sample gas from the test ports to the FTIR instrument and the THC analyzer.
4.1 SAMPLING SYSTEM DESCRIPTION
4.1.1  Sample System Components
       The sampling system consists of three separate components:
       1. Two sample probe assemblies;
       2. Two sample lines  and pumps; and
       3. A gas distribution manifold cart.
       All wetted surfaces of the system are made of unreactive materials, Teflon®, stainless
steel, or glass and  are maintained at temperatures at or above 300° F to prevent condensation.
       The sample probe assembly consists of the sample probe, a prefilter, a primary particulate
filter, and an electronically actuated spike valve. The sample probe is a standard heated probe
assembly with a pitot tube and thermocouple. The prefilter is a threaded piece of tubing loaded
with glass wool attached to the end of sample probe.  The primary filter is a Balston particulate
filter with a 99 percent removal efficience at 0.1 fj.m. The actuated spike valve is controlled by a
radio transmitter connected to a switch on the sample manifold cart. All sample probe assembly
components are attached to or enclosed in an insulated metal box.
       The sample lines are  standard heated sample lines with three 3/8-in. Teflon tubes in 10,25,
50, and 100 foot (ft) lengths.  The pumps are heated, single-headed diaphragm pumps
manufactured by either KNF Neuberger or Air Dimensions.. These pumps can sample at rates up
                                          25

-------
to 20 liters per minute (Lpm) depending on the pressure drop created by the components installed
upstream.
       The gas~3istribution manifold was specially constructed for FUR sampling by MRI.  It is
built onto a cart that can be operated inside the MRI mobile lab or in an alternate location, if
necessary. The manifold consists of a secondary paniculate filter, control valves, rotameters, back
pressure regulators and gauges, and a mass flow controller. The manifold can control two sample
gas stream inputs, eight calibration gases, and has three individual outputs for analyzers. Also on
the cart are a computer work station and controls for the spike valves and mass flow controller.
4.1.2  Sample Gas Stream Flow
       Exhaust gas was withdrawn through the sample probe and transported to the gas
distribution manifold. Inside the manifold the gas passed through separate secondary paniculate
filters. Downstream of the secondary filters, part of each sample gas stream was directed to
separate THC analyzers; one to measure the inlet concentration and another to measure the outlet
concentration. Part of the remaining sample gas from each stream was either sent to the FTIR
instrument for analysis or exhausted with the remaining portion of the gas stream being sampled
(i.e., when the inlet sample was analyzed the stack sample was exhausted and vice versa). This
was accomplished by rotating the gas selection valves to allow the appropriate sample gas to pass
the instrument inlet port. The gas flow to the instruments was regulated by needle valves on
rotameters at the manifold outlets.
4.2 SAMPLING PROCEDURES
       Sampling was conducted at all sampling locations using either one of two identical, but
separate, sample systems which were both connected to the main manifold (Figure 4).  A single
FTIR instrument and one THC  analyzer were used to sample all locations. The 4-way valves on
the outlets of the common manifold could be used to select sample from either location at any
given time. For several of the tests, sampling was performed using both sample lines, with the
FTIR and THC alternating between locations every 30 minutes.  Sample flow to each instrument
was controlled by the use of the rotameter needle valves.

-------
FTIR SAMPLES
       Sampling was conducted using either batch or the continuous sampling procedures,
described belowT All data were collected according to the Method 320 sampling procedure, which
is described below.
4.2.1 Batch Samples
       In this procedure, the 4-way valve on the manifold outlet was turned to divert a portion of
the sample flow to the FTIR cell.  A positive flow to the main manifold outlet vent was
maintained as the cell was filled to just above ambient pressure.  The cell inlet valve was then
closed to isolate the sample, the cell outlet valve was open to vent the cell to ambient pressure, the
spectrum of the static sample was recorded, and then'the cell was evacuated for the next sample.
This procedure was repeated to collect as many samples as possible during the test run.
       Batch sampling has the advantage that every sample is unique from the other samples. The
time resolution of the measurements is limited by the interval required to pressurize the cell, and
record the spectrum. All of the spiked samples and all of the samples for Run 2 APP Holding
Tank 1 were collected using this procedure.
4.2.2 Continuous Sampling
       The cell was filled as in the batch sampling procedure, but the cell inlet and outlet valves
were kept open to keep gas continuously flowing through the cell. The inlet and outlet flows were
regulated to keep the sample at ambient pressure. The flow through the cell was maintained at
about 5 Lpm. The cell volume was about 7 L.
       The FTIR instrument was automated to record spectra of the flowing sample about every
2 min. The automated analytical program was revised after the test was completed and all of the
spectra were reanalyzed to measure the pollutants of interest.
       This procedure with automated data collection was used for all of the unspiked testing.
Because spectra were collected continuously as the sample flowed through the cell, there was
mixing between consecutive samples. The interval between independent measurements (and the
time resolution) depends on the sample flow rate (through the cell), and the cell volume. The
following explanation is taken from Draft Performance Specification 15, which is for FTIR
GEMS.
                                           28

-------
       The Time Constant, TC, is the period for one cell volume to flow through the cell. The
TC determines the minimum interval for complete removal of an analyte from the cell volume.  It
depends on the-sampling rate (Rs in LPM), the cell volume (Vcell in L) and the analyte's chemical
and physical properties.
                                               -                                     (1)
                                            Ks
       Performance Specification 15 defines 5 * TC as the minimum interval between
independent samples.
       A stainless steel tube ran from the cell inlet connection point to the front of the cell. The
outlet vent was at the back of the cell so that the flowing sample passed through the greatest
portion of the cell volume.
4.3 ANALYTE SPIKING
       Since there was little information available about HAP emissions from this source, there
was no plan for validating specific HAPs at this test. MRI conducted spiking for QA purposes
with using a cylinder standard of 104 ppmp-xylene and 4 ppm SF6 in nitrogen.
4.3.1  Analyte Spiking Procedures
       The infrared spectrum is ideally suited for analyzing and evaluating spiked samples
because many compounds have very distinct infrared spectra.
       The reason for analyte spiking is to provide a quality assurance check that the sampling
system can transport the spiked analyte(s) to the instrument and that the quantitative analysis
program can measure the analyte in the sample gas matrix. If at least 12 (independent) spiked and
12 (independent) unspiked samples are measured, then this procedure can be used to perform a
Method 301 validation.3
       The spike procedure follows Sections 9.2 and 13 of EPA draft Method 320. In this
procedure a gas standard is measured directly in the cell. This direct measurement is then
compared to measurements of the analyte in spiked samples.  Ideally, the spike will comprise
about 1/10 or less of the spiked sample. The expected concentration of the spiked component is
determined using a tracer gas, SF6. The SF6 concentration in the direct sample divided by the SF6
concentration in the spiked sample(s) is used as the spike dilution factor (DF). The analyte
                                           29

-------
standard concentration divided by DF gives the expected value of the spiked analyte
concentration.
       For all testing activities on September 22, 1997, MRI generated spike gas by blending two
gas streams through two separate mass flow controllers. One gas stream contained toluene and
one contained SF6. Because of this two controller approach, these spikes are likely less reliable
than those performed on subsequent days. [Final spectral analysis will prove/disprove this.]
       For testing on September 23 through September 26, MRI performed spiking by flowing a
gas blend of SF6 and p-xylene through a single mass flow controller. Because of the relatively
low concentration available and low absorbance of p-xylene, spike flows were set to 1 to 2 Lpm,
or approximately 1/6 to 1/3 of the total sample flow-. The spike recovery results are presented in
Table 6 in Section 3.
4.3.2 Analysis of Spiked Results
       The statistical procedures in Section 6.3 of EPA Method 301 were followed to analyze the
spiked and unspiked results. The application of these procedures to FTIR test data is described in
Section 13 of EPA Method 320.  This involved evaluating the measurement precision,
determining any systematic bias  in the results, and calculating a correction factor that can be
applied to the results when the validated method is used.
4.3.3 Determination of Percent Recovery
       The expected concentration of the spiked component was determined using the tracer gas,
SF6. In the following discussion the "direct" measurement refers to the measured concentration in
a spectrum of a sample taken directly from the spike cylinder mixture.
       The dilution factor, DF, was determined by the ratio of the measured SF6 concentration in
the direct measurement of the spike mixture, SF6(direct), to the measured SF6 concentration in the
spiked samples, SF6(spike).
                                         op
                                  DF =    6(direct)                                     (2)
The direct measurement of the analyte concentration in the spike mixture divided by DF gives the
expected concentration for a 100 percent recovery of the analyte spike, Cexp.

where "Calc" is equal to the differences between the measured analyte concentrations in spiked
and unspiked samples.
4.4 ANALYTICAL PROCEDURES
       Analytical procedures in the EPA FTIR Protocol2 were followed for this test, and
programs were prepared prior to the field test for use in analyzing the data on site. The programs
employ automated routines to analyze the spectra using mathematical techniques based on a
K-matrix analysis to determine analyte concentrations and an estimated uncertainty for each
measurement.5"7 After the field test the input data (reference spectra) were modified based on the
real appearance of the sample spectra.  The subtracted residual baseline spectra were analyzed to
estimate uncertainties in the reported concentrations.
       Calculated concentrations in sample spectra were corrected for differences in absorption
path length and temperature between the reference and sample spectra by
where:
      Ccorr =  concentration, corrected for path length and temperature
      Ccalc =  concentration, initial calculation (output of the analytical program designed for the
              compound)
         L,. =  conference spectrum path length
         Ls =  sample spectrum path length

4.4.1  Program Input
       Several versions of program input data were used in analyzing the Port Arthur spectra.
Some of the  spectra were qualitative and so concentrations of these compounds are not presented
in the results tables. Table 11 summarizes the quantitative version of program input reference
data. This information was used to calculate the reported concentration results.  A second
qualitative version of the program input was used to gain insight into other compounds in the
emissions. Results from the second version were used to compile the information summarized in
Table 5.
       Table 12 summarizes the input data used to evalutate the ethylene CTS spectra. This CTS
analysis was used as an independent determination of the cell path length.   To analyze the CTS
spectra, MRI used 0.25 cm"1 spectra "cts0814b" and "cts0814c." These reference CTS spectra
were recorded on the same dates as the toluene reference spectra used in the analysis.  These
spectra were deresolved to 1.0 cm"1 in the same way as the toluene reference spectra using Section
K.2.2 of the EPA FTIR.protocol. The program analyzed the main two ethylene bands centered
near 2,989 and 949 cm"1.  Table 12 summarizes the results of the CTS analysis. The cell path
length from this analysis was used as Ls in equation 5.
4.4.2  EPA Reference Spectra
       The quantitative reference spectra used in the analysis were taken from the EPA reference
spectrum library (http://134.67.104.12/html/emtic/ftir2.htm).  The original sample and
background interferograms were truncated to the first 16,384 data points. The new interferograms
were then Fourier transformed using Norton-Beer medium apodization and no zero filling. The
transformation parameters agreed with those used to collect the sample spectra.  The deresolved
1.0 cm"1 single beam spectra were combined with their deresolved single beam background
spectra and converted to absorbance. This same procedure was used to prepare spectral standards
for the HAP's and other compounds included in the preliminary analysis.
       For qualitative analysis some spectra from the Hanst spectral library (Infrared Analysis,
Inc.) were used.

4.5 FTIR SYSTEM
      The FTIR system used in this field test was a KVB/Analect RFX-40 interferometer. The
gas cell is a heated variable path (D-22H) gas cell from Infrared Analysis, Inc. The path length of
36 laser passes was used for measurement at both locations. The inside of the cell walls have
been treated with a Teflon® coating to minimize potential analyte losses. A mercury/cadmium/
telluride (MCT) liquid nitrogen detector was used. Spectra was collected at 1.0 cm"1, the highest
resolution of the RFX-40 system. The cell was maintained at 240°F throughout the test series.
      The optical path length was measured by shining a He/Ne laser into the cell and adjusting
the mirror tilt until the desired number of passes was obtained.  The path length in meters was
then calculated by comparing calibration transfer standard (CTS, ethylene in nitrogen) spectra
measured in the field to CTS spectra in the EPA reference spectrum library. Section 5.2 (QA/QC
procedures) shows results of these calculations.
4.6 CONTINUOUS EMISSIONS MONITORING FOR TOTAL HYDROCARBONS (THC)
      The THC sampling was conducted continuously by taking a split of the gas used for the
FTIR sampling.  Sample gas was directed to the THC analyzer through a separate set of
rotameters and control valves. A summary of the specific procedures used is given below.
                                         34

-------
4.6.1  Components
       A brief description of each system component follows.
       1. THCAnalyzer—The THC concentration is measured using a flame ionization detector
(FID). MRI used two J.U.M. Model VE-7 instruments.  The THC analyzers were operated on the
zero to 100 ppm and 1,000 ppm ranges throughout the test period. The fuel for the FID is
40 percent hydrogen and 60 percent helium mixture.
       2. Data Acquisition System—MRI uses LABTECH notebook (Windows version), which
is an integrated system that provides data acquisition, monitoring and control. The system
normally writes data to a disk in the background while performing foreground tasks or displaying
data in real time. This system runs on a Pentium computer with a 700- megabyte hard drive and
expanded memory.
       3. Calibration Gases—Calibration gases were prepared from an EPA Protocol 1 cylinder
of propane using an Environics Model 2020 gas dilution system which complies with the
requirements of EPA Method 205. High, Medium and Low standards gases were generated to
perform analyzer calibration checks.
       The calibration gases were generated from 5,278 ppm propane in nitrogen standard. The
raw data are reported in ppm as propane.

5.0 SUMMARY OF QA/QC PROCEDURES
5.1 SAMPLING AND TEST CONDITIONS
      Before the test, sample lines were checked for leaks and cleaned by purging with moist air
(250°F). Following this, the lines were checked for contamination using dry nitrogen. This is
done by heating the sampling lines to 250°F and purging with dry nitrogen. The FTIR cell was
filled with some of the purging nitrogen and the spectrum of this sample was collected. This
single beam spectrum was converted to absorbance using a spectral background of pure nitrogen
(99.9 percent) taken directly from a cylinder. The lines were checked again on site before
sampling, after each change of location, and after spiking.
      During sampling, spectra of at least 10 different samples were collected during each hour,
except for Run 2 on the APP Holding Tank 1, for which batch collection was necessary.
      Each spectrum was assigned a unique file name and written to the hard disk and a backup
disk under that file name. Each interferogram was also saved under a file name that identifies it
with its corresponding absorbance spectrum. All background spectra and calibration spectra were
also stored on disks with their corresponding interferograms.
      Notes on each calibration and sample spectrum were recorded on hard copy data sheets.
Below are listed some sampling and instrument parameters that were documented in these
records.

      •   Line temperature
      •   Process conditions
      •   Sample flow rate
      •   Ambient pressure
       •   Time of sample collection
Instrument Configuration
       •   Cell volume (for continuous measurements)
       •   Cell temperature

       •   Length of time to measure spectrum
       •   Time spectrum was collected
       •   Time, and conditions of recorded background spectrum
       •   Time and conditions of relevant CTS spectra
       •   Apodization
       Hard copy records were also kept of all flue gas measurements, such as sample flow,
temperature, moisture and diluent data.
       Effluent was allowed to flow through the entire sampling system for at least 5 min before a
sampling run started or after changing to a different test location. FTIR spectra were monitored in
an effort to limit deviations in the spectral baseline to no greater than ±5 percent (-0.02

interferograms, if necessary.
       To measure HAPs detected in the gas stream, MRI used spectra from the EPA library,
when available.
5.3 METHOD 25A
5.3.1  Initial Checks
       Before starting the first run, the following system checks were performed.
       1.  Zero and Span check of the analyzer;
       2.  Analyzer linearity check at intermediate levels;
       3.  Response time of the system; and
       4.  Calibration criterion for Method 25 A is ±5 percent of calibration gas value.
5.3.2 Daily Checks
       The following checks were made for each test run.
       1.  Zero/Span calibration and Linearity check prior to each test run; and
       2.  Final Zero and Span calibrations of the analyzer at the end of each test run.
       The difference between initial and final zero and span checks agreed within ±3 percent of
the instrument span.

                                                      Horizontal Duct - Row Away From Observer
        Comments:  Note that the FT1R and THC sampling is conducted in this cross section. Duct
                   location and accessibility do not provide adequate measurement conditions.
                   Flow measurements are made before and after pollutant sampling through the
                   single port One traverse is used because flow rate is very low and velocity
                   variation across the duct is not significant enough to affect representativeness
                   of the measurements.

order,.Methods 320, 321,  and 322 to read as follows:
             Appendix A to Part 63-Test Methods
                            *****
                  (PROPOSED)  TEST METHOD 320
 MEASUREMENT OF VAPOR PHASE ORGANIC AND INORGANIC EMISSIONS
BY EXTRACTIVE FOURIER TRANSFORM INFRARED (FTIR) SPECTROSCOPY
1.0  Introduction.
     Persons unfamiliar with basic elements of FTIR
spectroscopy should not attempt to use this method.  This
method describes sampling and analytical procedures for
extractive emission measurements using Fourier transform
infrared  (FTIR) spectroscopy.  Detailed analytical
procedures for interpreting infrared spectra are described
in the "Protocol for the Use of Extractive Fourier Transform
Infrared  (FTIR) Spectrometry .in Analyses of Gaseous
Emissions from Stationary Sources," hereafter referred to as
the "Protocol."  Definitions not given in this method are
given in appendix A of the Protocol.  References to specific
sections in the Protocol are made throughout this Method.
For additional information refer to references 1 and 2, and
other EPA reports, which describe the use of FTIR
spectrometry in specific field measurement applications and
validation tests.  The sampling procedure described here is
extractive.  Flue gas is extracted through a heated gas
transport and handling system.  For some sources, sample
conditioning systems may be applicable.  Some examples are
given in this method.  Note:  sample conditioning systems
may be used providing the method validation requirements in
Sections 9.2 and 13.0 of this method are met.
1.1  Scope and Applicability.
1.1.1  Analytes.  Analytes include hazardous air pollutants
(HAPs) for which EPA reference spectra have been developed.
Other compounds can also be measured with this method if
reference spectra are prepared according to section 4.6 of
the protocol.
1.1.2  Applicability.  This method applies to the analysis
of vapor phase organic or inorganic compounds which absorb
energy in the mid-infrared spectral region, about 400 to
4000 cm"1  (25 to 2.5 um).  This method is used  to determine
compound-specific concentrations in a multi-component vapor
phase sample, which is contained in a closed-path gas cell.
Spectra of samples are collected using double beam infrared
absorption spectroscopy.  A computer program is used to
analyze spectra and report compound concentrations.
1.2  Method Range and Sensitivity.  Analytical range and
sensitivity depend on the frequency-dependent analyte
absorptivity, instrument configuration, data collection
parameters, and gas stream composition.  Instrument factors
include:  (a) spectral resolution,  (b) interferometer signal

-------
averaging time,  (c) detector sensitivity and response, and
(d) absorption path length.
1.2.1  For any optical configuration the analytical range is
between the absorbance values of about .01 (infrared
transmittance relative to the background = 0.98) and 1.0 (T
= 0.1).   (For absorbance > 1.0 the relation between
absorbance and concentration may not be linear.)
1.2.2  The concentrations associated with this absorbance
range depend primarily on the cell path length and the
sample temperature.  An analyte absorbance greater than 1.0,
can be lowered by decreasing the optical path length.
Analyte absorbance increases with a longer path length.
Analyte detection also depends on the presence of other
species exhibiting absorbance in the same analytical region.
Additionally, the estimated lower absorbance  (A) limit (A =
0.01) depends on the root mean square deviation (RMSD) noise
in the analytical region.
1.2.3  The concentration range of this method is determined
by the choice of optical configuration.
1.2.3.1  The absorbance for a given concentration can be
decreased by decreasing the path length or by diluting the
sample.  There is no practical upper limit to the
measurement range.
1.2.3.2  The analyte absorbance for a given concentration
may be increased by increasing the cell path length or (to
some extent) using a higher resolution.  Both modifications
also cause a corresponding increased absorbance for all
compounds in the sample, and a decrease in the signal
throughput.  For this reason the practical lower detection
range  (quantitation limit) usually depends on sample
characteristics such as moisture content of the gas, the
presence of other interferants, and losses in the sampling
system.
1.3  Sensitivity.  The limit of sensitivity for an optical
configuration and integration time is determined using
appendix D of the Protocol:  Minimum Analyte Uncertainty,
(MAU).  The MAU depends on the RMSD noise in an analytical
region, and on the absorptivity of the analyte in the same
region.
1.4  Data Quality.  Data quality shall be determined by
executing Protocol pre-test procedures in appendices B to H
of the protocol and post-test procedures in appendices I and
J of the protocol.
1.4.1  Measurement objectives shall be established by the
choice of detection limit  (DLj.)  and analytical uncertainty
(AUJ  for each analyte.
1.4.2  An instrumental configuration shall be selected.  An
estimate of gas composition shall be made based on previous
test data, data from a similar source or information

-------
gathered in a pre-test site survey.  Spectral interferants
shall be identified using the selected DLj.  and AUt and band
areas from reference spectra and interferant spectra.  The
baseline noise of the system shall be measured in each
analytical region to determine the MAU of the instrument
configuration for each analyte and interferant (MIUX) .
1.4.3  Data quality for the application shall be determined,
in part, by measuring the RMS (root mean square)  noise level
in each analytical spectral region (appendix C of the
Protocol).  The RMS noise is defined as the RMSD of the
absorbance values in an analytical region from the mean
absorbance value in the region.
1.4.4  The MAU is the'minimum analyte concentration .for
which the AUi can be maintained;  if the measured  analyte
concentration is less than MAUi_,  then data  quality are
unacceptable.
2.0  Summary of Method.
2.1  Principle.  References 4 through 7 provide background
material on infrared spectroscopy and quantitative analysis.
A summary is given in this section.
2.1.1  Infrared absorption spectroscopy is performed by
directing an infrared beam through a sample to a detector.
The frequency-dependent infrared absorbance of the sample is
measured by comparing this detector signal  (single beam
spectrum) to a signal obtained without a sample in the beam
path (background).
2.1.2  Most molecules absorb infrared radiation and the
absorbance occurs in a characteristic and reproducible
pattern.  The infrared spectrum measures fundamental
molecular properties and a compound can be identified from
its infrared spectrum alone.
2.1.3  Within constraints, there is a linear relationship
between infrared absorption and compound concentration.  If
this frequency dependent relationship  (absorptivity) is
known (measured), it can be used to determine compound
concentration in a sample mixture.
2.1.4  Absorptivity is measured by preparing, in the
laboratory, standard samples of compounds at known
concentrations and measuring the FTIR "reference spectra" of
these standard samples.  These "reference spectra" are then
used in sample analysis:   (I) compounds are detected by
matching sample absorbance bands with bands in reference
spectra, and  (2) concentrations are measured by comparing
sample band intensities with reference band intensities.
2.1.5  This method is self-validating provided that the
results meet the performance requirement of the QA spike in
sections 9.0 and 8.6.2 of this method, and results from a
previous method validation study support the use of this
method in the application.

-------
2.2  Sampling and Analysis.  In extractive sampling a probe
assembly and pump are used to extract gas from the exhaust
of the affected source and transport the sample to the FTIR
gas cell.  Typically, the sampling apparatus is similar to
that used for single-component continuous emission monitor
(CEM) measurements.
2.2.1  The digitized infrared spectrum of the sample in the
FTIR gas cell is measured and stored on a computer.
Absorbance band intensities in the spectrum are related to
sample concentrations by what is commonly referred to as
Beer's Law.
where:
     Ax = absorbance at a given frequency of the ith sample
          component.
     at = absorption coefficient  (absorptivity) of the ith
          sample component.
     b  = path length of the cell.
     cx = concentration of the ith sample component.
2.2.2  Analyte spiking is used for quality assurance (QA).
In this procedure  (section 8.6.2 of this method) an analyte
is spiked into the gas stream at the back end of the sample
probe.  Analyte concentrations in the spiked samples are
compared to analyte concentrations in unspiked samples.
Since the concentration of the spike is known,  this
procedure can be used to determine if the sampling system is
removing the spiked analyte(s) from the sample stream.
2.3 Reference Spectra Availability.  Reference spectra of
over 100 HAPs are available in the EPA FTIR spectral library
on the EMTIC (Emission Measurement Technical Information
Center) computer bulletin board service and at internet
address http://info.arnold.af.mil/epa/welcome.htm.
Reference spectra for HAPs, or other analytes,  may also be
prepared according to section 4.6 of the Protocol.
2.4  Operator Requirements.  The FTIR analyst shall be
trained in setting up the instrumentation, verifying the
instrument is functioning properly, and performing routine
maintenance.  The analyst must evaluate the initial sample
spectra to determine if the sample matrix is consistent with
pre-test assumptions and if the instrument configuration is
suitable.  The analyst must be able to modify the instrument
configuration,  if necessary.
2.4.1  The spectral analysis shall be supervised by someone
familiar with EPA FTIR Protocol procedures.
2.4.2  A technician trained in CEM test methods is qualified
to install and operate the sampling system.  This includes

-------
installing the probe and heated line assembly, operating the
analyte spike system, and performing moisture and flow
measurements.
3.0  Definitions.
     See appendix A of the Protocol for definitions relating
to infrared spectroscopy.  Additional definitions are given
below.
3.1  Analyte.  A compound that this method is used to
measure.  The term "target analyte" is also used.  This
method is multi-component and a number of analytes can be
targeted for a test.
3.2  Reference Spectrum.  Infrared spectrum of an analyte
prepared under controlled, documented, and reproducible
laboratory conditions according to procedures in section 4.6.
of the Protocol.  A library of reference spectra is used to
measure analytes in gas samples.
3.3  Standard Spectrum.  A spectrum that has been prepared
from a reference spectrum through a  (documented)
mathematical operation.  A common example is de-resolving of
reference spectra to lower-resolution standard spectra
(Protocol, appendix K).  Standard spectra, prepared by
approved, and documented, procedures can be used as
reference spectra for analysis.
3.4  Concentration.  In this method concentration is
expressed as a molar concentration, in ppm-meters, or in
(ppm-meters)/K, where K is the absolute temperature
(Kelvin).  The latter units allow the direct comparison of
concentrations from systems using different optical
configurations or sampling temperatures.
3.5  Interferant.  A compound in the sample matrix whose
infrared spectrum overlaps with part of an analyte spectrum.
The most accurate analyte measurements are achieved when
reference spectra of interferants are used in the
quantitative analysis with the analyte reference spectra.
The presence of an interferant. can increase the analytical
uncertainty in the measured analyte concentration.
3.6  Gas Cell.  A gas containment cell that can be
evacuated.  It is equipped with the optical components to
pass the infrared beam through the sample to the detector.
Important cell features include: path length  (or range if
variable), temperature range, materials of construction, and
total gas volume.
3.7  Sampling System.  Equipment used to extract the sample
from the test location and transport the sample gas to the
FTIR analyzer.  This includes sample conditioning systems.
3.8  Sample Analysis.  The process of interpreting the
infrared spectra to obtain sample analyte concentrations.
This process is usually automated using a software routine

-------
employing a classical least squares  (els), partial least
squares  (pis), or K- or P- matrix method.
3.9  One hundred percent line.  A double beam transmittance
spectrum obtained by combining two background single beam
spectra.  Ideally, this line is equal to 100 percent
transmittance  (or zero absorbance) at every frequency in the
spectrum.  Practically, a zero absorbance line is used to
measure the. baseline noise in the spectrum.
3.10  Background Deviation.  A deviation from 100 percent
transmittance in any region of the 100 percent line.
Deviations greater than ± 5 percent in an analytical region
are unacceptable  (absorbance of 0.021 to -0.022).  Such
deviations indicate a change in the instrument throughput
relative to the background single beam.
3.11  Batch Sampling.  A procedure where spectra of
discreet, static samples are collected.  The gas cell is
filled with sample and the cell is isolated.  The spectrum
is collected.  Finally, the cell is evacuated to prepare for
the next sample.
3.12 .Continuous Sampling.  A procedure where spectra are
collected while sample gas is flowing through the cell at a
measured rate.
3.13  Sampling resolution.  The spectral resolution used to
collect sample spectra.
3.14  Truncation.  Limiting the number of interferogram data
points by deleting points farthest from the center burst
(zero path difference, ZPD).
3.15  Zero filling.  The addition of points to the
interferogram.  The position of each added point is
interpolated from neighboring real data points.  Zero
filling adds no information to the interferogram, but
affects line shapes in the absorbance spectrum (and possibly
analytical results).
3.16  Reference CTS.  Calibration Transfer Standard spectra
that were collected with reference spectra.
3.17  CTS Standard.  CTS spectrum produced by applying a de-
resolution procedure to a reference CTS.
3.18  Test CTS.  CTS spectra collected at the sampling
resolution using the same optical configuration as for
sample spectra.  Test spectra help verify the resolution,
temperature and path length of the FTIR system.
3.19  RMSD.  Root Mean Square Difference, defined in EPA
FTIR Protocol, appendix A.
3.20  Sensitivity.  The noise-limited compound-dependent
detection limit for the FTIR system configuration.  This is
estimated by the MAU.  It depends on the RMSD in an
analytical region of a. zero absorbance line.
3.21  Quantitation Limit.  The lower limit of detection for
the FTIR system configuration in the sample spectra.  This

-------
is estimated by mathematically subtracting scaled reference
spectra of analytes and interferences from sample spectra,
then measuring the RMSD in an analytical region of the
subtracted spectrum.  Since the noise in subtracted sample
spectra may be much greater than in a zero absorbance
spectrum,, the quantitation limit is generally much higher
than the sensitivity.  Removing spectral interferences from
the sample or improving the spectral subtraction can lower
the quantitation limit toward (but not below)  the
sensitivity.
3.22  Independent Sample.  A unique volume of sample gas;
there is no mixing of gas between two consecutive
independent samples.  In continuous sampling two independent
samples are separated by at least 5 cell volumes.  The
interval between independent measurements depends on the
cell volume and the sample flow rate  (through the cell).
3.23  Measurement.  A single spectrum .of flue gas contained
in the FTIR cell.
3.24  Run.  A run consists of a series of measurements.   At
a minimum a run includes 8 independent measurements spaced
over- 1 hour.
3.25  Validation.  Validation of FTIR measurements is
described in sections 13.0 through 13.4 of this method.
Validation is used to verify the test procedures for
measuring specific analytes at a source.  Validation
provides proof that the method works under certain test
conditions.
3.26  Validation Run.  A validation run consists of at least
24 measurements of independent samples.  Half of the samples
are spiked and half are not spiked.  The length of the run
is determined by the interval between independent samples.
3.27  Screening.  Screening is used when there is little or
no available information about a source.  The purpose of
screening is to determine what analytes are emitted and to
obtain information about important sample characteristics
such as moisture, temperature, and interferences.  Screening
results are semi-quantitative (estimated concentrations) or
qualitative  (identification only).  Various optical and
sampling configurations may be used.  Sample conditioning
systems may be evaluated for their effectiveness in removing
interferences.  It is unnecessary to perform a complete run
under any set of sampling conditions.  Spiking is not
necessary, but spiking can be a useful screening tool for
evaluating the sampling system, especially if a reactive or
soluble analyte is used for the spike.
3.28  Emissions Test.  An FTIR emissions test is performed
according specific sampling and analytical procedures.
These procedures, for the target analytes and the source,
are based on previous screening and validation results.

-------
Emission results are quantitative.  A QA spike  (sections
8.6.2 and 9.2 of this method) is performed under each set of
sampling conditions using a representative analyte.  Flow,
gas temperature and diluent data are recorded concurrently
with the FTIR measurements to provide mass emission rates
for detected compounds.
3.29  Surrogate.  A surrogate is a compound that is used in
a QA spike procedure (section 8.6.2 of this method) to
represent other compounds.  The chemical and physical
properties of a surrogate shall be similar to the compounds
it is chosen to represent.  Under given sampling conditions,
usually a single sampling factor is of primary concern for
measuring the target analytes:  for example, the surrogate
spike results can be representative for analytes that are
more reactive, more soluble, have a lower absorptivity, or
have a lower vapor pressure than the surrogate itself.

4.0  Interferences.
     Interferences are divided into two classifications:
analytical and sampling.
4.1  Analytical Interferences.  An analytical interference
is a spectral feature that complicates (in extreme cases may
prevent) the analysis of an analyte.  Analytical
interferences are classified as background or spectral
interference.
4.1.1  Background Interference.  This results from a change
in throughput relative to the single beam background.  It is
corrected by collecting a new background and proceeding with
the test.  In severe instances the cause must be identified
and corrected.  Potential causes include: (1)  deposits on
reflective surfaces or transmitting windows, (2) changes in
detector sensitivity,  (3) a change in the infrared source
output, or (4.) failure in the instrument electronics.  In
routine sampling throughput may degrade over several hours.
Periodically a new background must be collected, but no
other corrective action will be required.
4.1.2  Spectral Interference.  This results from the
presence of interfering compound(s) (interferant) in the
sample.  Interferant spectral features overlap analyte
spectral features.  Any compound with an infrared spectrum,
including analytes, can potentially be an interferant.  The
Protocol measures absorbance band overlap in each analytical
region to determine if potential interferants shall be
classified as known interferants  (FTIR Protocol, section 4.9
and appendix B).  Water vapor and C02  are common spectral
interferants.  Both of these compounds have strong infrared
spectra and are present in many sample matrices at high
concentrations relative to analytes.  The extent of
interference depends on the  (1) interferant concentration,

-------
 (2) analyte concentration, and  (3) the degree of band
overlap.  Choosing an alternate analytical region can
minimize or avoid the spectral interference.  For example/
C02 interferes with the analysis of the 670 cm'1 benzene
band.  However, benzene can also be measured near 3000 cm"1
 (with less sensitivity).
4.2  Sampling System Interferences.  These prevent analytes
from reaching the instrument.  The analyte spike procedure
is designed to measure sampling system interference, if any.
4.2.1  Temperature.  A temperature that is too low causes
condensation of analytes or water vapor.  The materials of
the sampling system and the FTIR gas cell usually set the
upper limit of temperature.
4.2.2  Reactive Species.  Anything that reacts with
analytes.  Some analytes, like formaldehyde, polymerize at
lower temperatures.
4.2.3  Materials.  Poor choice of material for probe, or
sampling line may remove some analytes.  For example, HF
reacts with glass components.
4.2.4  Moisture.  In addition to being a spectral
interferant, condensed moisture removes soluble compounds.
5.0  Safety.
     The hazards of performing this method are those
associated with any stack sampling method and the same
precautions shall be followed.  Many HAPs are suspected
carcinogens or present other serious health risks.  Exposure
to these compounds should be avoided in all circumstances.
For instructions on the safe handling of any particular
compound, refer to its material safety data sheet.  When
using analyte standards, always ensure that gases are
properly vented and that the gas handling system is leak
free.  (Always perform a leak check with the system under
maximum vacuum and, again, with the system at greater than
ambient pressure.)   Refer to section 8.2 of this method for
leak check procedures.  This method does not address all of
the potential safety risks associated with its use.  Anyone
performing this method must follow safety and health
practices consistent with applicable legal requirements and
with prudent practice for each application.
6.0  Equipment and Supplies.
     Note:  Mention of trade names or specific products does
     not constitute endorsement by the Environmental
     Protection Agency.
     The equipment and supplies are based on the schematic
of a sampling system shown in Figure 1.  Either the batch or
continuous sampling procedures may be used with this
sampling system.  Alternative sampling configurations may
also be used,  provided that the data quality objectives are
met as determined in the post-analysis evaluation.  Other

-------
                             10

equipment or supplies may be necessary, depending on the
design of the sampling system or the specific target
analytes.
6.1  Sampling Probe.  Glass, stainless steel, or other
appropriate material of sufficient length and physical
integrity, to sustain heating, prevent adsorption of
analytes, and to transport analytes to the infrared gas
cell.  Special materials or configurations may be required
in some applications.  For instance, high stack sample
temperatures may require special steel or cooling the probe.
For very high moisture sources it may be desirable to use a
dilution probe.
6.2  Particulate Filters.  A glass wool plug  (optional)
inserted at the probe tip  (for large particulate removal)
and a filter (required) rated for 99 percent removal
efficiency at 1-micron (e.g., Balston")  connected at the
outlet of the heated probe.
6.3  Sampling Line/Heating System.  Heated (sufficient to
prevent condensation) stainless steel,
polytetrafluoroethane, or other material inert to the
analytes.
6.4  Gas Distribution Manifold.  A heated manifold allowing
the operator to control flows of gas standards and samples
directly to the FTIR system or through sample conditioning
systems.  Usually includes heated flow meter, heated valve
for selecting and sending sample to the analyzer, and a by-
pass vent.  This is typically constructed of stainless steel
tubing and fittings, and high-temperature valves.
6.5  Stainless Steel Tubing.  Type 316, appropriate diameter
(e.g., 3/8 in.) and length for heated connections.  Higher
grade stainless may be desirable in some applications.
6.6  Calibration/Analyte Spike Assembly.  A three way valve
assembly  (or equivalent)  to introduce analyte or surrogate
spikes into the sampling system at the outlet of the probe
upstream of the out-of-stack particulate filter and the FTIR
analytical system.
6.7  Mass Flow Meter  (MFM).  These are used for measuring
analyte spike flow. The MFM shall be calibrated in the range
of 0 to 5 L/min and be accurate to ± 2 percent (or better)
of the flow meter span.
6.8  Gas Regulators.  Appropriate for individual gas
standards.
6.9  Polytetrafluoroethane Tubing.  Diameter  (e.g., 3/8 in.)
and length suitable to connect cylinder regulators to gas
standard manifold.
6.10  Sample Pump.  A leak-free pump  (e.g., KNF") ,  with by-
pass valve, capable of producing a sample flow rate of at
least 10 L/min through 100 ft of sample line.  If the pump
is positioned upstream of the distribution manifold and FTIR

-------
                             11

system, use a heated pump that is constructed from materials
non-reactive to the analytes.  If the pump is located
downstream of. the FTIR system, the gas cell sample pressure
will be lower than ambient pressure and it must be recorded
at regular intervals.
6.11  Gas Sample Manifold.  Secondary manifold to control
sample flow at the inlet to the FTIR manifold.  This is
optional, but includes a by-pass vent and heated rotameter.
6.12  Rotameter.  A 0 to 20 L/min rotameter.  This meter
need not be calibrated.
6.13  FTIR Analytical System.  Spectrometer and detector,
capable of measuring the analytes to the chosen detection
limit.  The system shall include a personal computer with
compatible software allowing.automated collection of
spectra.
6.14  FTIR Cell Pump.  Required for the batch sampling
technique, capable of evacuating the FTIR cell volume within
2 minutes.  The pumping speed shall allow the operator to
obtain 8 sample spectra in 1 hour.
6.15  Absolute Pressure Gauge.  Capable of measuring
pressure from 0 to 1000 mmHg to within ±'2.5 mmHg  (e.g.,
Baratron") .
6.16  Temperature Gauge.  Capable of measuring the cell
temperature to within ± 2°C.
6.17  Sample Conditioning.  One option is a condenser
system, which is used for moisture removal.  This can be
helpful in the measurement of some analytes.  Other sample
conditioning procedures may be devised for the removal of
moisture or other interfering species.
6.17.1  The analyte spike procedure of section 9.2 of this
method, the QA spike procedure of section 8.6.2 of this
method, and the validation procedure of section 13 of this
method demonstrate whether the sample conditioning affects
analyte concentrations.  Alternatively, measurements can be
made with two parallel FTIR systems; one measuring
conditioned sample, the other measuring unconditioned
sample.
6.17.2  Another option is sample dilution.  The dilution
factor measurement must be documented and accounted for in
the reported concentrations.  An alternative to dilution is
to lower the sensitivity of the FTIR system by decreasing
the cell path length, or to use a short-path cell in
conjunction with a long path cell to measure more than one
concentration range.
7.0  Reagents and Standards.
7.1  Analyte(s) and Tracer Gas.  Obtain a certified gas
cylinder mixture containing all of the analyte(s) at
concentrations within ± 2 percent of the -emission source
levels  (expressed in ppm-meter/K).  If practical, the

-------
      .-.-••-'             12

analyte standard cylinder shall also contain the tracer gas
at a concentration which gives a measurable absorbance at a
dilution factor of at least 10:1.  Two ppm SF6 is sufficient
for a path length of 22 meters at 250 °F.
7.2  Calibration Transfer Standard(s).  Select the
calibration transfer standards  (CTS) according to section
4.5 of the FTIR Protocol.  Obtain a National Institute of
Standards and Technology  (NIST) traceable gravimetric
standard of the CTS  (± 2 percent).
7.3  Reference Spectra.  Obtain reference spectra for each
analyte/ interferant, surrogate, CTS, and tracer.  If EPA
reference spectra are not available, use reference spectra
prepared according to procedures in section 4.6 of the EPA
FTIR Protocol.
8.0  Sampling and Analysis Procedure.
     Three types of testing can be performed:  (1) screening,
(2) emissions test, and  (3) validation.  Each is defined in
section 3 of this method.  Determine the purpose(s) of the
FTIR test.  Test requirements include:  (a) AUif  DLt, overall
fractional uncertainty, OFUif  maximum expected concentration
(CMAXi),  and tM for each, (b)  potential interferants,  (c)
sampling system factors, e.g., minimum absolute cell
pressure, (Prain),  FTIR cell volume (Vss), estimated sample
absorption, pathlength, Ls',  estimated sample pressure,  Ps',
Ts',  signal  integration time (tss),  minimum instrumental
linewidth, MIL, fractional error, and  (d) analytical
regions, e.g., m = 1 to M, lower wavenumber position,  FLm/
center wavenumber position, FCra,  and upper wavenumber
position, FUm,  plus interferants,  upper wavenumber position
of the CTS absorption band, FFUm,  lower wavenumber position
of the CTS absorption band, FFLm,  wavenumber range FNU to
FNL.  If necessary, sample and acquire an initial spectrum.
From analysis of this preliminary spectrum determine a
suitable operational path length.  Set up the sampling train
as shown in Figure 1 or use an appropriate alternative
configuration.  Sections 8.1 through 8.11 of this method
provide guidance on pre-test calculations in the EPA
protocol, sampling and analytical procedures, and post-test
protocol calculations.
8.1  Pretest Preparations and Evaluations.  Using the
procedure in section 4.0 of the FTIR Protocol, determine the
optimum sampling system configuration for measuring the
target analytes.  Use available information to make
reasonable assumptions about moisture content and other
interferences.
8.1.1  Analytes.  Select the  required detection limit  (DLJ
and the maximum permissible analytical uncertainty  (AUJ  for
each analyte  (labeled from 1  to i).  Estimate, if possible,
the maximum expected concentration for each analyte,

-------
                             13

The expected measurement range is fixed by DLX and CMAXt for
each analyte (i).
8.1.2  Potential Interferants.  List the potential
interferants.  This usually includes water vapor and C02,
but may also include some analytes and other compounds.
8.1.3.  Optical Configuration.  Choose an optical
configuration that can measure all of the analytes within
the absorbance range of .01 to 1.0  (this may require more
than one path length).  Use Protocol sections 4.3 to 4.8 for
guidance in choosing a configuration and measuring CTS.
8.1.4.  Fractional Reproducibility Uncertainty  (FRUJ .   The
FRU is determined for each analyte by comparing CTS spectra
taken before and after the reference spectra were measured.
The EPA para-xylene reference spectra were collected on
10/31/91 and 11/01/91 with corresponding CTS spectra
"cts!031a," and "ctsllOlb."  The CTS spectra are used to
estimate the reproducibility  (FRU) in the system that was
used to collect the references.  The FRU must be < AU.
Appendix E of the protocol is used to calculate the FRU from
CTS spectra.  Figure 2 plots results for 0.25 cm"1 CTS
spectra in EPA reference library: S3 (ctsllOlb - cts!031a),
and S4 [(ctsllOlb + cts!031a)/2].   The RMSD (SRMS)  is
calculated in the subtracted baseline, S3/  in the
corresponding CTS region from 850 to 1065 cm"1.  The area
(BAV) is calculated in the same region of the averaged CTS
spectrum, S4.
8.1.5  Known Interferants.  Use appendix B of the EPA FTIR
Protocol.
8.1.6  Calculate the Minimum Analyte Uncertainty, MAU
(section 1.3 of this method discusses MAU and protocol
appendix D gives the MAU procedure).  The MAU for each
analyte, i, and each analytical region, m, depends on the
RMS noise.
8.1.7  Analytical Program.  See FTIR Protocol, section 4.10.
Prepare computer program based on the chosen analytical
technique.  Use as input reference spectra of all target
analytes and expected interferants.  Reference spectra of
additional compounds shall also be included in the program
if their presence  (even if transient) in the samples is
considered possible.  The program output shall be in ppm (or
ppb) and shall be corrected for differences between the
reference path length, LR/  temperature,  TR, and pressure, PR,
and the conditions used for collecting the sample spectra.
If sampling is performed at ambient pressure, then any
pressure correction is usually small relative to corrections
for path length and temperature, and may be neglected.
8.2  Leak-check.
8.2.1  Sampling System.  A typical FTIR extractive sampling
train is shown in Figure 1.  Leak check from the probe tip

-------
             -                14

to pump outlet as follows:  Connect a 0- to 250-mL/min rate
meter (rotameter or bubble meter) to the outlet of the pump.
Close off the inlet to the probe, and record the leak rate.'
The leak rate shall be <; 200 mL/min.
8.2.2  Analytical System Leak check.  Leak check the FTIR
cell under vacuum and under pressure (greater than ambient).
Leak check connecting tubing and inlet manifold under
pressure.
8.2.2.1  For the evacuated sample technique, close the valve
to the FTIR cell, and evacuate the absorption cell to the
minimum absolute pressure Prain.   Close the valve to the pump,
and determine the change in pressure APV after  2  minutes.
8.2.2.2  For both the evacuated sample and purging
techniques, pressurize the system to about 100 mmHg above
atmospheric pressure.  Isolate the pump and determine the
change in pressure APP after  2  minutes.
8.2.2.3  Measure the barometric pressure, Pb in mmHg.
8.2.2.4  Determine the percent leak volume %VL  for the
signal integration time tss and for APmax, i.e.,  the larger of
APV or APP, as follows:

           %VL = 50 tss i!=i          '  '                (2)
where 50 = 100% divided by the leak-check time of 2 minutes.
8.2.2.5  Leak volumes in excess of 4 percent of the FTIR
system volume Vss are unacceptable.
8.3  Detector Linearity.  Once an optical configuration is
chosen, use one of the procedures of sections 8.3.1 through
8.3.3 to verify that the detector response is linear.  If
the detector response is not linear, decrease the aperture,
or attenuate the infrared beam.  After a change in the
instrument configuration perform a linearity check until it
is demonstrated that the detector response is linear.
8.3.1  Vary the power incident on the detector by modifying
the aperture setting.  Measure the background and CTS at
three instrument aperture settings:  (I) at the aperture
setting to be used in the testing,  (2) at one half this
aperture and (3) at twice the proposed testing aperture.
Compare the three CTS spectra.  CTS band areas shall agree
to within the uncertainty of the cylinder standard and the
RMSD noise in the system.  If test aperture is the maximum
aperture, collect CTS spectrum at maximum aperture, then
close the aperture to reduce the IR throughput by half.
Collect a second background and CTS at the smaller aperture
setting and compare the spectra again.

-------
                             15

8.3.2  Use neutral density filters to attenuate the infrared
beam.  Set up the FTIR system as it will be used in the test
measurements.  Collect a CTS spectrum.  Use a neutral
density filter to attenuate the infrared beam (either
immediately after the source or the interferometer) to
approximately 1/2 its original intensity.  Collect a second
CTS spectrum.  Use another filter to attenuate the infrared
beam to approximately 1/4 its original intensity.  Collect a
third background and CTS spectrum.  Compare the CTS spectra.
CTS band areas shall agree to within the uncertainty of the
cylinder standard and the RMSD noise in the system.
8.3.3  Observe the single beam instrument response in a
frequency region where the detector response is known to be
zero.  Verify that the detector response is "flat" and equal
to zero in these regions.
8.4  Data Storage Requirements.  All field test spectra
shall be stored on a computer disk and a second backup copy
must stored on a separate disk.  The stored information
includes sample interferograms, processed absorbance
spectra, background interferograms, CTS sample
interferograms and CTS absorbance spectra.  Additionally,
documentation of all sample conditions, instrument settings,
and test records must be recorded on hard copy or on
computer medium.  Table 1 gives a sample presentation of
documentation.
8.5  Background Spectrum.  Evacuate the gas cell to z 5
mmHg, and fill with dry nitrogen gas to ambient pressure  (or
purge the cell with 10 volumes of dry nitrogen).  Verify
that no significant amounts of absorbing species  (for
example water vapor and C02)  are present.   Collect a
background spectrum, using a signal averaging period equal
to or greater than the averaging period for the sample
spectra.  Assign a unique file name to the background
spectrum.  Store two copies of the background interferogram
and processed single-beam spectrum on separate computer
disks (one copy is the back-up).
8.5.1  Interference Spectra.  If possible, collect spectra
of known and suspected major interferences using the same
optical system that will be used in the field measurements.
This can be done on-site or earlier.  A number of gases,
e.g. C02,  S02/ CO, NH3,  are readily available from cylinder
gas suppliers.
8.5.2  Water vapor spectra can be prepared by the  following
procedure.  Fill a sample tube with distilled water.
Evacuate above the sample and remove dissolved gasses by
alternately freezing and thawing the water while evacuating.
Allow water vapor into the FTIR cell, then dilute  to
atmospheric pressure with nitrogen or dry air.  If
quantitative water spectra are required, follow the

-------
                             16

reference spectrum procedure for neat samples (protocol,
section. 4.6).  Often, interference spectra need not be
quantitative, but for best results the absorbance must be
comparable to the interference absorbance in the sample
spectra.
8.6  Pre-Test Calibrations
8.6.1  Calibration Transfer Standard.  Evacuate the gas cell
to £ 5 mmHg absolute pressure, and fill the FTIR cell to
atmospheric pressure with the CTS gas.  Alternatively, purge
the cell with 10 cell volumes of CTS gas.  (If purge is
used, verify that the CTS concentration in the cell is
stable by collecting two spectra 2 minutes apart as the CTS
gas continues to flow.  If the absorbance in the second
spectrum is no greater than in the first, within the
uncertainty of the gas standard, then this can be used as
the CTS spectrum.)   Record the spectrum.
8.6.2  QA Spike.  This procedure assumes that the method has
been validated for at least some of the target analytes at
the source.  For emissions testing perform a QA spike.  Use
a certified standard, if possible, of an analyte, which has
been validated at the source.  One analyte standard can
serve as a QA surrogate for other analytes which are less
reactive or less soluble than the standard.  Perform the
spike procedure of section 9.2 of this method.  Record
spectra of at least three independent (section 3.22 of this
method) spiked samples.  Calculate the spiked component of
the analyte concentration.  If the average spiked
concentration is within 0.7 to 1.3 times the expected
concentration, then proceed with the testing.  If
applicable, apply the correction factor from the Method 301
of this appendix validation test  (not the result from the QA
spike).
8.7  Sampling.  If analyte concentrations vary rapidly with
time, CEM sampling is preferable using the smallest cell
volume, fastest sampling rate and fastest spectra collection
rate possible.  CEM sampling requires the least operator
intervention even without an automated sampling system.  For
continuous monitoring at one location over long periods,  CEM
sampling is preferred.  Batch sampling and continuous static
sampling are used for screening and performing test runs of
finite duration.  Either technique is preferred for sampling
several locations in a matter of days.  Batch sampling gives
reasonably good time resolution and ensures that each
spectrum measures a discreet  (and unique) sample volume.
Continuous static (and CEM) sampling provide a very stable
background over long periods.  Like batch sampling,
continuous static sampling also ensures that each spectrum
measures a unique sample volume.  It is essential that the
leak check procedure under vacuum (section 8.2 of this

-------
                             17

method) is passed if the batch sampling procedure is used.
It is essential that the leak check procedure under positive
pressure is passed if the continuous static or GEM sampling
procedures are used.  The sampling techniques are described
in sections 8.7.1 through 8.7.2 of this method.
8.7.1  Batch Sampling.  Evacuate the absorbance cell to
z 5 mmHg absolute pressure.  Fill the cell with exhaust gas
to ambient pressure, isolate the cell, and record the
spectrum.  Before taking the next sample, evacuate the cell
until no spectral evidence of sample absorption remains.
Repeat this procedure to collect eight spectra of separate
samples in 1 hour.
8.7.2  Continuous Static Sampling.  Purge the FTIR cell with
10 cell volumes of sample gas.  Isolate the cell, collect
the spectrum of the static sample and record the pressure.
Before'measuring the next sample, purge the cell with 10
more cell volumes of sample gas.
8.8  Sampling QA and Reporting.
8.8.1  Sample integration times shall be sufficient to
achieve the required signal-to-noise ratio.  Obtain an
absorbance spectrum by filling the cell with N2.   Measure
the RMSD in each analytical region in this absorbance
spectrum.  Verify that the number of scans used is
sufficient to achieve the target MAU.
8.8.2  Assign a unique file name to each spectrum.
8.8.3  Store two copies of sample interferograms and
processed spectra on separate computer disks.
8.8.4  For each sample spectrum, document the sampling
conditions, the sampling time  (while the cell was being
filled), the time the spectrum was recorded, the
instrumental conditions  (path length, temperature, pressure,
resolution, signal integration time), and the spectral file
name.  Keep a hard copy of these data sheets.
8.9  Signal Transmittance.  While sampling, monitor the
signal transmittance.  If signal transmittance (relative  to
the background) changes by 5 percent or more  (absorbance  =
-.02 to  .02) in any analytical spectral region, obtain a  new
background spectrum.
8.10   Post-test CIS.  After the sampling run, record another
CTS spectrum.

8.11   Post-test QA.
8.11.1   Inspect the sample spectra immediately after the  run
to verify that the gas matrix composition was close to the
expected  (assumed) gas matrix.
8.11.2  Verify that the sampling and  instrumental parameters
were appropriate for the conditions encountered.  For
example, if the moisture is much greater than anticipated,

-------
       • -    .      •          18

it may be necessary to use a shorter path length or dilute
the sample.
8.11.3  Compare the pre- and post-test GTS spectra.  The
peak absorbance in pre- and post-test CIS must be ± 5
percent of the mean value.  See appendix E of the FTIR
Protocol.
9.0  Quality Control.
     Use analyte spiking  (sections 8.6.2, 9.2 and 13.0 of
this method) to verify that the sampling system can
transport the analytes from the probe to the FTIR system.
9.1  Spike Materials.  Use a certified standard (accurate to
± 2 percent) of the target analyte, if one can be obtained.
If a certified standard cannot be obtained, follow the
procedures in section 4.6.2.2 of the FTIR Protocol.
9.2  Spiking Procedure.  QA spiking (section 8.6.2 of this
method) is a calibration procedure used before testing.  QA
spiking involves following the spike procedure of sections
9.2.1 through 9.2.3 of this method to obtain at least three
spiked samples.  The analyte concentrations in the spiked
samples shall be compared to the expected spike
concentration to verify that the sampling system is working
properly.  Usually, when QA spiking is used, the method has
already been validated at a similar source for the analyte
in question.  The QA spike demonstrates that the validated
sampling conditions are being duplicated.  If the QA spike
fails then the sampling system shall be repaired before
testing proceeds.  The method validation procedure (section
13.0 of this method) involves a more extensive use of the
analyte spike procedure of sections 9.2.1 through 9.2.3 of
this method.  Spectra of at least 12 independent spiked and
12 independent unspiked samples are recorded.  The
concentration results are analyzed statistically to
determine if there is a systematic bias in the method for
measuring a particular analyte.  If there is a systematic
bias, within the limits allowed by Method 301 of this
appendix, then a correction factor shall be applied to the
analytical results.  If the systematic bias is greater than
the allowed limits, this method is not valid and cannot be
used.
9.2.1  Introduce the spike/tracer gas at a constant flow
rate of * 10 percent of the total sample flow.  (Note;  Use
the rotameter at the end of the sampling train to estimate
the required spike/tracer gas flow rate.)  Use a flow
device, e.g., mass flow meter  (± 2 percent), to monitor the
spike flow rate.  Record the spike flow rate every 10
minutes.
9.2.2  Determine the response time (RT) of the system by
continuously collecting spectra of the spiked effluent until
the spectrum of the spiked component is constant for 5

-------
                             19

minutes.  The RT is the interval  from  the first measurement
until the spike becomes constant.  Wait  for twice the
duration of the RT, then collect  spectra of two independent
spiked gas samples.  Duplicate analyses of the spiked
concentration shall be within 5 percent of the mean of the
two measurements.
9.2.3  Calculate the dilution ratio using the tracer gas as
follows:
                   CE1

             w =  ir1^                              (3)
where:
                  Spike.,,.
             cs'-Tsr*                             <«
     DF   =    Dilution factor of the  spike gas; this value
               shall be *10.
          =    SF6  (or  tracer  gas) concentration measured
               directly in undiluted spike gas.
SFs(3Pio     =    Diluted SF6  (or tracer gas) concentration
               measured in a  spiked  sample.
Spikedir   =    Concentration  of the  analyte in  the spike
               standard measured by  filling the  FTIR cell
               directly.
     CS   =    Expected concentration  of  the  spiked samples.
10.0  Calibration and Standardization.

10.1  Signal-to-Noise Ratio (S/N).   The  RMSD  in the noise

must be less than one tenth of the  minimum analyte peak

absorbance in each analytical region.  For example if the

minimum peak absorbance is 0.01 at  the required-DL, then

RMSD measured over the entire analytical region must be

* 0.001.

-------
                             20
10.2  Absorbance Path length.  Verify the absorbance path
length by comparing reference CTS spectra to test CTS
spectra.  See appendix E of the FTIR Protocol.
10.3  Instrument Resolution.  Measure the line width of
appropriate test CTS band(s) to verify instrument
resolution.  Alternatively, compare CTS spectra to a
reference CTS spectrum, if available, measured at the
nominal resolution.
10.4  Apodization Function.  In transforming the sample
interferograms to absorbance spectra use the same
apodization function that was used in transforming the
reference spectra.
10.5  FTIR Cell Volume.  Evacuate the cell to s 5 mmHg.
Measure the initial absolute temperature (TJ  and absolute
pressure  (Pi) .   Connect a wet test  meter (or a calibrated
dry gas meter), and slowly draw room air into the cell.
Measure the meter volume  (VJ ,  meter absolute temperature
(TJ ,  and meter absolute pressure (Pm) ; and  the cell final
absolute temperature (TE)  and absolute  pressure (Pf) .
Calculate the FTIR cell volume Vss,  including  that of the
connecting tubing, as follows:

11.0  Data Analysis and Calculations.



     Analyte concentrations shall be measured using



reference spectra from the EPA FTIR spectral library.   When



EPA library spectra are not available,  the procedures  in



section 4.6 of the Protocol shall be followed to prepare



reference spectra of all the target analytes.



11.1  Spectral De-resolution.  Reference spectra can be



converted to lower resolution standard spectra  (section 3.3



of this method) by truncating the original reference sample



and background interferograms.  Appendix K of the FTIR



Protocol gives specific deresolution procedures.  Deresolved



spectra shall be transformed using the same apodization



function and level of zero filling as the sample spectra.



Additionally, pre-test FTIR protocol calculations (e.g.,



FRU, MAU, FCU) shall be performed using the de-resolved



standard spectra.



11.2  Data Analysis.  Various analytical programs are



available for relating sample absorbance to a concentration



standard.  Calculated concentrations shall be verified by



analyzing residual baselines after mathematically



subtracting scaled reference spectra from the sample



spectra.  A full description of the data analysis and



calculations is contained in the FTIR Protocol  (sections

concentrations in the sample spectra for differences in

and sample spectra using equation 6,

     L3  =  Sample spectra path length.

     Tr  =  Absolute gas temperature of reference spectra,  K.



12.0  Method Performance.



12.1  Spectral Quality.  Refer to the FTIR Protocol



appendices for analytical requirements, evaluation of data



quality, and analysis of uncertainty.



12.2  Sampling QA/QC.  The analyte spike procedure of



section 9 of this method, the QA spike of section 8.6.2 of



this method, and the validation procedure of section 13 of



this method are used to evaluate the performance of the



sampling system and to quantify sampling system effects, if



any, on the measured concentrations.  This method is self-



validating provided that the results meet the performance

-------
                             23



requirement of the QA spike in sections 9.0 and 8.6.2 of



this method and results from a previous method validation



study support the use of this method in the application.



Several factors can contribute to uncertainty in the



measurement of spiked samples.  Factors which can be



controlled to provide better accuracy in the spiking



procedure are listed in sections 12.2.1 through 12.2.4 of



this method.



12.2.1  Flow meter.  An accurate mass flow meter is accurate



to ± 1 percent of its span.  If a flow of 1 L/min is



monitored with such a MFM, which is calibrated in the range



of 0-5 L/min, the flow measurement has an uncertainty of 5



percent.  This may be improved by re-calibrating the meter



at the specific flow rate to be used.



12.2.2  Calibration gas.  Usually the calibration standard



is certified to within ± 2 percent.  With reactive analytes,



such as HC1, the certified accuracy in a commercially



available standard may be no better than ± 5 percent.



12.2.3  Temperature.  Temperature measurements of the cell



shall be quite accurate.  If practical, it is preferable to



measure sample temperature directly, by inserting a



thermocouple into the cell chamber instead of monitoring the



cell outer wall temperature.

-------
                             24
12.2.4  Pressure.  Accuracy depends on the accuracy of the
barometer, but fluctuations in pressure throughout a day may
be as much as 2.5 percent due to weather variations.
13.0  Method Validation Procedure.
    This validation procedure, which is based on EPA Method
301 (40 CFR part 63, appendix A),  may be used to validate
this method for the analytes in a gas matrix.  Validation at
one source may also apply to another type of source, if it
can be shown that the exhaust gas characteristics are
similar at both sources.
13.1  Section 5.3 of Method 301 (40 CFR'part 63, appendix
A), the Analyte Spike procedure,  is used with these
modifications.  The statistical analysis of the results
follows section 6.3 of EPA Method 301.  Section 3 of this
method defines terms that are not defined in Method 301.
13.1.1  The analyte spike is performed dynamically.  This
means the spike flow is continuous and constant as spiked
samples are measured.
13.1.2  The spike gas is introduced at the back of the
sample probe.
13.1.3  Spiked effluent is carried through all sampling
components downstream of the probe.
13.1.4  A single FTIR system  (or more) may be used to
collect and analyze spectra  (not quadruplicate integrated
sampling trains).

-------
       /                     25



13.1.5  All of the validation measurements are performed



sequentially in a single "run" (section 3.26 of this



method).




13.1.6  The measurements analyzed statistically are each



independent (section 3.22 of this method).



13.1.7  A validation data set can consist of more than 12



spiked and 12 unspiked measurements.



13.2  Batch Sampling.  The procedure in sections 13.2.1



through 13.2.2 may be used for stable processes.  If process



emissions are highly variable, the procedure in section



13.2.3 shall be used.



13.2.1  With a single FTIR instrument and sampling system,



begin by collecting spectra of two unspiked samples.



Introduce the spike flow into the sampling system and allow



10 cell volumes to purge the sampling system and FTIR cell.



Collect spectra of two spiked samples.  Turn off the spike



and allow 10 cell volumes of unspiked sample to purge the



FTIR cell.  Repeat this procedure until the 24  (or more)



samples are collected.



13.2.2  In batch sampling, collect spectra of 24 distinct



samples.   (Each distinct sample consists of filling the cell



to ambient pressure after the cell has been evacuated.)



13.2.3  Alternatively, a separate probe assembly, line, and




sample pump can be used for spiked sample.  Verify and



document that sampling conditions are,the same  in both the

-------
                             26



spiked and the unspiked sampling systems.  This can be done



by wrapping both sample lines in the same heated bundle.



Keep the same flow rate in both sample lines.  Measure



samples in sequence in pairs.  After two spiked samples are



measured, evacuate the FTIR cell, and turn the manifold



valve so that spiked sample flows to the FTIR cell.  Allow



the connecting line from the manifold to the FTIR cell to



purge thoroughly (the time depends on the line length and



flow rate).  Collect a pair of spiked samples.  Repeat the



procedure until at least 24 measurements are completed.



13.3  Simultaneous Measurements With Two FTIR Systems.  If



unspiked effluent concentrations of the target analyte(s)



vary significantly with time, it may be desirable to perform



synchronized measurements of spiked and unspiked sample.



Use two FTIR systems, each with its own cell and sampling



system to perform simultaneous spiked and unspiked



measurements.  The optical configurations shall be similar,



if possible.  The sampling configurations shall be the same.



One sampling system and FTIR analyzer shall be used to



measure spiked effluent.  The other sampling system and FTIR



analyzer shall be used to measure unspiked flue gas.  Both



systems shall use the same sampling procedure  (I.e., batch



or continuous).

-------
                             27
13.3.1  If batch sampling is used, synchronize the cell
evacuation, cell filling, and collection of spectra.  Fill
both cells at the same rate (in cell volumes per unit time).
13.3.2  If continuous sampling is used, adjust the sample
flow through each gas cell so that the same number of cell
volumes pass through each cell in a given time (i.e. TCj  =
TC2) .
13.4  Statistical Treatment.  The statistical procedure of
EPA Method 301 of this appendix, section 6.3 is used to
evaluate the bias and precision.  For FTIR testing a
validation "run" is defined as spectra of 24 independent
samples, 12 of which are spiked with the analyte(s) and 12
of which are not spiked.
13.4.1  Bias.  Determine the bias (defined by EPA Method 301
of this appendix, section 6.3.2) using equation 7:
            B=Sm-Mm-CS                             (7)
where:
       B =    Bias at spike  level.
      Sm =    Mean concentration of the  analyte  spiked
             samples.
      M,, =    Mean concentration of the  unspiked samples.
      CS =    Expected concentration  of  the  spiked samples.
13.4.2  Correction  Factor.  Use section 6.3.2.2 of Method
301 of  this appendix to-  evaluate  the statistical
significance of  the bias.  If  it  is determined that the bias

-------
                             28



is significant, then use section 6.3.3 of Method 301 to



calculate a correction factor  (CF).  Analytical results of



the test method are multiplied by the correction factor,  if



0.7 * CF s 1.3.  If is determined that the bias is



significant and CF > ± 30 percent,  then the test method is



considered to "not valid."



13.4.3  If measurements do not pass validation, evaluate the



sampling system, instrument configuration, and analytical



system to determine if improper set-up or a malfunction was



the cause.  If so, repair the system and repeat the



validation.



14.0  Pollution Prevention.



    The extracted sample gas is vented outside the



enclosure containing the FTIR system and gas manifold after



the analysis.  In typical method applications the vented



sample volume is.a small fraction of the source volumetric



flow and its composition is identical to that emitted from



the source.  When analyte spiking is used, spiked pollutants



are vented with the extracted sample gas.  Approximately 1.6



x 10'4 to 3.2 x 10'4  Ibs of  a  single  HAP may be  vented  to  the



atmosphere in a typical validation run of 3 hours.  (This



assumes a molar mass of 50 to 100 g, spike rate of 1.0



L/min, and a standard concentration of 100 ppm).  Minimize



emissions by keeping the spike flow off when not in use.



15.0  Waste Management.

-------
                             29


    Small volumes of laboratory gas standards can be vented


through a laboratory hood.  Neat samples must be packed and


disposed according to applicable regulations.  Surplus


materials may be returned to supplier for disposal.

      PROTOCOL FOR THB USB OF EXTRACTIVE FOURIER TRANSFORM
     INFRARED (FTIR)  SPBCTROMETRY FOR THB ANALYSES  OF  GASEOUS
                EMISSIONS FROM STATIONARY SOURCES
INTRODUCTION
    The purpose of this document is to set general guidelines
for the use of modern FTIR spectroscopic methods for the analysis
of gas samples extracted from the effluent of stationary emission
sources.  This document outlines techniques for developing and
evaluating such methods and sets basic requirements for reporting
and quality assurance procedures.


1.0  NOMENCLATURE

    1.1  Appendix A lists definitions of the symbols and terms
used in this Protocol, many of which have been taken directly
from American Society for Testing and Materials  (ASTM)
publication E 131-90a, entitled "Terminology Relating to
Molecular Spectroscopy;"

    1.2  Except in the case of background spectra or where
otherwise noted, the term "spectrum" refers .to a double-beam
spectrum in units of absorbance vs. wavenumber  (cm"1).

    1.3  The term "Study" in this document refers to a
publication that has been subjected to EPA- or peer-review.


2.0  APPLICABILITY AND ANALYTICAL PRINCIPLE

    2.1  Applicability.  This Protocol applies  to the
determination of compound-specific concentrations in single- and
multiple-component gas phase samples using double-beam absorption
spectroscopy in the mid-infrared band.  It does not specifically
address other FTIR applications, such as single-beam
spectroscopy, analysis of open-path (non-enclosed) samples, and
continuous measurement techniques.  'If multiple spectrometers,
absorption cells, or instrumental linewidths are used in such
analyses, each distinct operational configuration of the system
must be evaluated separately according to this Protocol.

    2.2  Analytical Principle.

    2.2.1  In the mid-infrared band, most molecules exhibit
characteristic gas phase absorption spectra that may be recorded
by FTIR systems.  Such systems consist of a source of mid-
infrared radiation, an interferometer, an enclosed sample cell of
known absorption pathlength, an infrared detector, optical
elements for the transfer of infrared radiation between
components, and gas flow control and measurement components.
Adjunct and integral computer systems are used  for controlling
the instrument, processing the signal, and for performing both
Fourier transforms and quantitative analyses of spectral data.

-------
    2.2.2  The absorption  spectra of pure gases and of mixtures
of gases are described by  a linear absorbance theory referred to
as Beer's Law.  Using this law, modern FTIR systems use
computerized analytical programs to quantify compounds by
comparing the absorption spectra of known (reference)  gas samples
to the absorption spectrum of the sample gas.  Some standard
mathematical techniques used for comparisons are classical least
squares, inverse least squares, cross-correlation, factor
analysis, and partial least squares.  Reference A describes
several of these techniques, as well as additional techniques,
such as differentiation methods, linear baseline corrections, and
non-linear absorbance corrections.


3.0  GENERAL PRINCIPLES OF PROTOCOL REQUIREMENTS

    The characteristics that distinguish FTIR systems from gas
analyzers used in instrumental gas analysis methods (e.g.,
EPA Methods 6C and 7E) are: (1) Computers are necessary to
obtain and analyze data; (2) chemical concentrations can be
quantified using previously recorded infrared reference spectra;
and (3) analytical assumptions and results,  including possible
effects of interfering compounds, can be evaluated after the
quantitative analysis.  The following general principles and
requirements of this Protocol are based on these characteristics.

    3.1  Veriflability and Reproducibility of Results.  Store
all data and document data analysis techniques sufficient to
allow an independent agent to reproduce the analytical results
from the raw in.terferometric data.

    3.2  Transfer of Reference Spectra.  To determine whether
reference spectra recorded under one set of conditions (e.g.,
optical bench, instrumental linewidth, absorption pathlength,
detector performance, pressure, and temperature)  can be used to
analyze sample spectra taken under a different set of conditions,
quantitatively compare "calibration transfer standards" (CTS) and
reference spectra as described in this Protocol.   (Note: The CTS
may,  but need not, include analytes of interest).  To effect
this,  record the absorption spectra of the CTS (a) immediately
before and immediately after recording reference spectra and
(b) immediately after recording sample spectra.

    3.3  Evaluation of FTIR Analyses.  The applicability,
accuracy, and precision of FTIR measurements are influenced by a
number of interrelated factors, which may be divided into two
classes:

    3.3.1  Sample-Independent Factors.  Examples are system
configuration and performance  (e.g., detector sensitivity and
infrared source output), quality and applicability of reference
absorption spectra, and type of mathematical analyses of the
spectra.  These factors define the fundamental limitations of
FTIR measurements for a given system configuration.  These
limitations may be estimated from evaluations of the system
before samples are available.  For example, the detection limit
for the absorbing compound under a given set of conditions may be

-------
estimated from the system noise level and the strength of a
particular absorption band.  Similarly, the accuracy of
measurements-may be estimated from the analysis of the reference
spectra.

    3.3.2  Sample-Dependent Factors.  Examples are spectral
interferants  (e.g., water vapor and C02)  or  the overlap of
spectral features of different compounds and contamination
deposits on reflective surfaces or transmitting windows.  To
maximize the  effectiveness of the mathematical techniques used in
spectral analysis,  identification of interferants (a standard
initial step)  and analysis of samples  (includes effects of other
analytical errors)  are necessary.  Thus, the Protocol requires
post-analysis calculation of measurement concentration
uncertainties for the detection of these potential sources of
measurement error.
4.0  PRB-TBST PREPARATIONS AMD EVALUATIONS

    Before  testing, demonstrate  the  suitability of FTIR
spectrometry for the desired application according to the
procedures  of this section.

    4.1  Identify Test  Requirements.   Identify  and record the
test requirements described below  in 4.1.1 through 4.1.5.  These
values set  the desired or required goals of the proposed
analysis; the description of methods for determining whether
these goals are actually met during  the analysis comprises the
majority of this Protocol.

    4.1.1   Analytes  (specific chemical species) of interest.
Label the analytes from i = 1 to I.

    4.1.2   Analytical  uncertainty  limit  (AUt) .   The AUt  is  the
maximum permissible fractional uncertainty of  analysis for the
ich  analyte  concentration, expressed  as a  fraction of the analyte
concentration in the sample.

    4.1.3   Required detection limit  for each analyte  (DL^,  ppm) .
The detection limit is the lowest  concentration of an analyte for
which its overall fractional uncertainty  (OFU^ is required to  be
less than its analytical uncertainty limit  (AUi) .

    4.1.4   Maximum expected concentration of each analyte
(CMAXt,  ppm) .

    4.2  Identify Potential Interferants.   Considering  the
chemistry of the process or results  of previous Studies, identify
potential interferants, i.e., the  major effluent constituents and
any relatively minor effluent constituents  that possess either
strong absorption characteristics  or strong structural
similarities to any analyte of interest.  Label them 1 through
N.J,  where the subscript "j"- pertains  to potential interferants.
Estimate the concentrations of these compounds in the effluent
(CPOT.J,  ppm) .

-------
    4.3  Select and Evaluate  the Sampling System.  Considering
the source, e.g.,  temperature and pressure profiles, moisture
content, analyte characteristics, and particulate concentration),
select the equipment for extracting gas samples.  Recommended are
a particulate filter,  heating system to maintain sample
temperature above the dew point for all sample constituents at
all points within the sampling system (including the filter), and
sample conditioning system  (e.g., coolers, water-permeable
membranes that remove water or other compounds from the sample,
and dilution devices)  to remove spectral interferants or to
protect the sampling and analytical components.  Determine the
minimum absolute sample system pressure (Pnin,  mmHg)  and the
infrared absorption cell volume  (Vss, liter) .   Select the
techniques and/or equipment for the measurement of sample
pressures and temperatures.

    4.4  Select Spectroscopic System.  Select  a spectroscopic
configuration for the application..  Approximate the absorption
pathlength (L3' , meter),  sample  pressure (P3' ,  kPa) , absolute
sample temperature Ts',  and signal  integration period (tss/
seconds) for the analysis.  Specify the nominal minimum
instrumental linewidth (MIL) of the system.  Verify that the
fractional error at the approximate values Pg'  and Ts' is leas
than one half the smallest value AUi (see  Section  4.1.2).
    4.5  Select Calibration Transfer Standards  (CTS's).  Select
CTS's that meet the criteria listed in Sections 4.5.1, 4.5.2, and
4.5.3.

    Mote:  It may be necessary to choose preliminary analytical
    regions  (see Section 4.7), identify the minimum analyte
    linewidths, or estimate the  system noise level  (see
    Section  4.12) before selecting the CTS.  More than one
    compound may be needed to meet the criteria; if so, obtain
    separate cylinders  for each  compound.

    4.5.1  The central-  wavenumber position of each analytical
region lies within 25 percent of the wavenumber position of at
least one CTS absorption band.

    4.5.2  The absorption bands  in 4.5.1 exhibit peak
absorbances greater than ten times the value RMSEST (see
Section 4.12) but less  than 1.5 absorbance units.

    4.5.3  At least one absorption CTS band within the operating
range of the FTIR instrument has an instrument -independent
linewidth no greater than the narrowest analyte absorption band;
perform and  document measurements or cite Studies to determine
analyte and CTS compound linewidths.

    4.5.4  For each analytical region, specify  the upper and
lower wavenumber positions (FFUm and FFLm, respectively) that
bracket the  CTS absorption band  or bands for the associated
analytical region.  Specify the wavenumber range, FNU to FNL,
containing the absorption band that meets the criterion of
Section 4.5.3.

-------
    4.5.5  Associate, whenever possible, a single set of CTS gas
cylinders with a set of reference spectra.  Replacement CTS gas
cylinders shall contain the same compounds at concentrations
within 5 percent of that of the original CTS cylinders; the
entire absorption spectra  (not individual spectral segments) of
the replacement gas shall be scaled by a factor between 0.95 and
1.05 to match the original CTS spectra.

    4.6  Prepare Reference Spectra.

    Note: Reference spectra are available in a permanent soft
    copy from the EPA spectral library on the EMTIC  (Emission
    Measurement Technical  Information Center) computer bulletin
    board; they may be used if applicable.

    4.6.1  Select the reference absorption pathlength  (L0)  of the
cell.

    4.6.2  Obtain or prepare a set of chemical standards for
each analyte, potential and known spectral interferants, and CTS.
Select the concentrations of the chemical standards to correspond
to the top of the desired range.

    4.6.2.1  Commercially-Prepared Chemical Standards.  Chemical
standards for many compounds may be obtained from independent
sources, such as a specialty gas manufacturer, chemical company,
or commercial laboratory.  These standards (accurate to within
±2 percent) shall be prepared according to EPA Protocol 1  (see
Reference D) or shall be traceable to NIST standards.  Obtain
from the supplier an estimate of the stability of the analyte
concentration; obtain and follow all the supplier's
recommendations for recertifying the analyte concentration.

    4.6.2.2  Self-Prepared Chemical Standards.  Chemical
standards may be prepared as follows:  Dilute certified
commercially prepared chemical gases or pure analytes with ultra-
pure carrier (UPC) grade nitrogen according to the barometric and
volumetric techniques generally described in Reference A,
Section A4.6.

    4.6.3  Record a set of the absorption spectra of the CTS
{Rl}, then a set of the reference spectra at two or more .
concentrations in duplicate over the desired range (the top of
the range must be less than 10 times that of the bottom),
followed by a second set of CTS spectra {R2}.  (If self-prepared
standards are used, see Section 4.6.5 before disposing of any of
the standards.)  The maximum accepted standard concentration-
pathlength product  (ASCPP) for each compound shall be higher than
the maximum estimated concentration-pathlength products for both
analytes and known interferants in the effluent gas.  For each
analyte, the minimum ASCPP shall be no greater than ten times the
concentration-pathlength product of that analyte at its required
detection limit.

    4.6.4  Permanently store the background and interferograms
in digitized form.  Document details of the mathematical process
for generating the spectra from these interferograms.  Record the

-------
sample pressure  (PR),  sample temperature (TR) ,  reference
absorption pathlength  (LR) ,  and interferogram signal integration
period (tSR).  Signal integration periods  for the background
interferograius shall be 2tSR.   Values  of PR, LR,  and tSR shall  not
deviate by more  than ±1 percent from  the time of recording {Rl}
to that of recording {R2}.

    4.6.5  If self-prepared chemical  standards  are  employed and
spectra of only  two concentrations are recorded for one or more
compounds, verify the accuracy of the dilution  technique by
analyzing the prepared standards for  those compounds with a
secondary (non-FTIR) technique as follows:

    4.6.5.1  Record the response of the secondary  technique to
each of the four standards  prepared.

    4.6.5.2  Perform a linear  regression of  the response values
(dependant variable) versus the accepted standard concentration
(ASC)  values (independent variable), with the regression
constrained to pass through the zero-response,  zero ASC point.

    4.6.5.3  Calculate the  average  fractional difference between
the actual response values  and the regression-predicted values
(those calculated from the  regression line using the four ASC
values as the independent variable).

    4.6.5.4  If  the average fractional difference value
calculated in Section 4.6.5.3  is larger for  any compound than the
corresponding AUt/  the dilution technique is not sufficiently
accurate and the reference  spectra prepared  are not valid for the
analysis.

    4.7  Select  Analytical  Regions.   Using  the  general
considerations in Section 7 of Reference A and  the  spectral
characteristics  of the analytes and interferants, select the
analytical regions for the  application.  Label  them m = 1 to M.
Specify the lower, center and  upper wavenumber positions of each
analytical region (FL,.,  FCm, and FUm/ respectively) .  Specify the
analytes and interferants which exhibit absorption  in each
region.

    4.8  Determine Fractional  Reproducibility Uncertainties.
Using Appendix E, calculate the fractional reproducibility
uncertainty for  each analyte  (FRUL)  from a comparison of {Rl}  and
{R2}.  If FRUt  > AUt for any analyte,  the  reference  spectra
generated in Section 4.6 are not valid for the  application.

    4.9  Identify Known Interferants.  Using Appendix B,
determine which  potential interferant affects the analyte
concentration determinations.  If it  does,  relabel  the potential
interferant as "known" interferant, and designate  these compounds
from k = 1 to K.  Appendix  B also provides  criteria for
determining whether the selected analytical  regions are suitable.

    4.10  Prepare Computerized Analytical  Programs.

-------
    4.10.1  Choose or devise mathematical techniques  (e.g,
classical least squares, inverse least squares, cross-
correlation, and factor analysis) based on Equation 4 of
Reference A that are appropriate for analyzing spectral data by
comparison with reference spectra.

    4.10.2  Following the general recommendations of  Reference
A, prepare a computer program or set of programs that analyzes
all the analytes and known interferants, based on the selected
analytical regions (4.7) and the prepared reference spectra
(4.6).  Specify the baseline correction technique (e.g.,
determining the slope and intercept of a linear baseline
contribution in each analytical region) for each analytical
region, including all relevant wavenumber positions.

    4.10.3  Use programs that provide  as output  [at the
reference absorption pathlength  (LR) ,  reference gas  temperature
(TR) ,  and reference gas  pressure (PRH  the analyte
concentrations, the known interferant  concentrations, .and the
baseline slope and intercept values.   If the sample absorption
pathlength  (Ls) ,  sample  gas temperature (Ts) or sample gas
pressure  (Ps)  during the actual sample analyses differ from LR,
TR,  and PR,  use a program or  set  of programs that applies
multiplicative corrections to the derived concentrations to
account for these variations, and that provides as output both
the corrected and uncorrected values.  Include  in the report of
the analysis  (see Section 7.0) the details of  any transformations
applied to  the original reference spectra (e.g.,
differentiation), in such a  fashion that all analytical results
may be verified by an independent agent from the reference
spectra and data spectra alone.

    4.11  Determine  the Fractional Calibration Uncertainty.
Calculate the fractional calibration uncertainty for  each analyte
(FCUi) according to Appendix F,  and compare these values to the
fractional  uncertainty  limits  (AU^-  see Section 4.1) .   If
FCUt > AUt), either the  reference spectra or analytical programs
for that analyte are unsuitable.

    4.12  Verify System Configuration  Suitability.    Using
Appendix C, measure or  obtain estimates of the  noise  level
(RMSgsr, absorbance) of the FTIR system; alternatively, construct
the complete spectrometer system and determine  the values RMS^
using Appendix G.  Estimate  the  minimum measurement uncertainty
for each analyte  (MAUt,  ppm)  and known interferant (MIUk, ppm)
using Appendix D.  Verify that  (a) MAUL < (AUt) (DLt) ,  FRUL < AUi(
and FCUt < AUt  for  each  analyte  and  that  (b)  the CTS  chosen meets
the requirements listed in Section 4.5.


5.0   SAMPLING AND ANALYSIS PROCEDURE

    5.1   Analysis  System Assembly and Leak-Test.  Assemble the
analysis  system.  Allow sufficient time for all system components
to reach  the desired temperature.  Then determine the leak-rate
(Lfl)  and leak volume (VL) ,  where VL = LR tss.  Leak volumes shall
be s4 percent of Vsg.

-------
    5.2  Verify  Instrumental  Performance.  Measure  the noise
level of the system in each analytical region using the procedure
of Appendix G.   If any noise  level is higher than that estimated
for the system in Section 4.12, repeat the calculations of
Appendix D and verify that the requirements of Section 4.12 are
met; if they are not, adjust  or repair the instrument and repeat
this section.

    5.3  Determine the Sample Absorption  Pathlength.  Record a
background spectrum.  Then, fill the absorption cell with CTS at
the pressure PR and record a set of CTS spectra {R3}.   Store the
background and unsealed CTS single beam interferograms and
spectra.  Using  Appendix H, calculate the sample absorption
pathlength (L3)  for each analytical region.   The values  Ls shall
not differ from  the approximated sample pathlength Ls'  (see
Section 4.4)  by  more than 5 percent.

    5.4  Record  Sample Spectrum.  Connect the  sample line to the
source.  Either  evacuate the  absorption cell to an absolute
pressure below 5 mmHg before  extracting a sample from the
effluent stream  into the absorption cell, or pump at least ten
cell volumes of  sample through the cell before obtaining a
sample.  Record  the sample pressure Ps.   Generate the absorbance
spectrum of the  sample.  Store the background and sample single
beam interferograms, and document the process by which the
absorbance spectra are generated from these data.   (If necessary,
apply the spectral transformations developed in Section 5.6.2).
The resulting sample spectrum is referred to below as Ss.

    Note;  Multiple sample spectra may be recorded according to
    the procedures of Section 5.4 before performing Sections 5.5
    and 5.6.

    5.5  Quantify Analyte Concentrations.  Calculate the
unsealed analyte concentrations RUAt and unsealed interferant
concentrations RUIK using the programs developed in Section  4.
To correct for pathlength and pressure variations between the
reference and sample spectra, calculate the scaling factor
RLPS = (LRPRTS) / (LSPSTR) .  .Calculate the  final  analyte  and
interferant concentrations RSAt = R^RUAi and RSI^ = RLPSRUIk.
    5.6  Determine  Fractional  Analysis  Uncertainty.  Fill  the
absorption cell with CTS at the pressure Ps.  Record a set of CTS
spectra  {R4} .  Store the background and CTS single beam
interferograms.  Using Appendix H, calculate the fractional
analysis uncertainty  (FAU) for each analytical region.  If the
FAU indicated for any analytical  region is  larger than the
required accuracy requirements determined in Section 4.1,  then
comparisons  to previously  recorded reference spectra are  invalid
in that analytical  region, and the analyst  shall perform .one or
both of the  following procedures :

    5.6.1  Perform  instrumental  checks  and  adjust the  instrument
to restore its performance -to  acceptable levels.  If adjustments
are made, repeat Sections  5.3, 5.4  (except  for the recording of a
sample spectrum), and 5.5  to demonstrate that acceptable
uncertainties are obtained in  all analytical regions.

-------
    5.6.2  Apply appropriate mathematical transformations  (e g
frequency shifting, zero-filling, apodization, smoothing) to the
spectra (or to the interferograms upon which the spectra are
based) generated during the performance of the procedures of
Section 5.3.  Document these transformations and their
reproducibility.  Do not apply multiplicative scaling of the
spectra, or any set of transformations that is mathematically
equivalent to multiplicative scaling.  Different transformations
may be applied to different analytical regions.  Frequency shifts
shall be smaller than one-half the minimum instrumental
linewidth, and must be applied to all spectral data points in an
analytical region.  The mathematical transformations may be
retained for the analysis if they are also applied to the
appropriate analytical regions of all sample spectra recorded,
and if all original sample spectra are digitally stored.  Repeat
Sections 5.3, 5.4  (except the recording of a sample spectrum),
and 5.5 to demonstrate that these, transformations lead to
acceptable calculated concentration uncertainties in all
analytical regions.


6.0  POST-ANALYSIS BVALUATIONS

    Estimate the overall accuracy of the analyses performed  in
Section 5 as follows:

    6.1  Qualitatively Confirm the Assumed Matrix.  Examine  each
analytical region of the sample  spectrum for spectral evidence of
unexpected or unidentified interferants.  If found, identify the
interfering compounds (see Reference C for guidance) and add them
to the list of known interferants.  Repeat the procedures of
Section 4 to include the interferants in the uncertainty
calculations and analysis procedures.  Verify that the MAU and
FCU values do not increase beyond acceptable levels for the
application requirements.  Re-calculate the analyte
concentrations  (Section 5.5) in  the affected analytical regions.
    6.2  Quantitatively Evaluate Fractional Model Uncertainty
(FMU).  Perform the procedures of either Section 6.2.1 or 6.2.2:

    6.2.1  Using Appendix  I, determine  the  fractional model
error  (FMU) for each analyte.

    6.2.2  Provide statistically determined uncertainties  FMU
for each analyte which are equivalent to two standard deviations
at the 95% confidence level.  Such determinations, if employed,
must be based on mathematical examinations of the pertinent
sample spectra  (not the reference spectra alone).  Include in the
report of the analysis  (see Section 7.0) a complete description
of the determination of the concentration uncertainties.

    6.3   Estimate  Overall  Concentration Uncertainty  (OCU).
Using Appendix J, determine the  overall concentration uncertainty
(OCU)  for each analyte.  If the  OCU is  larger than the required
accuracy for any analyte,  repeat Sections 4 and  6.

     law.  The units  "centimeters-ppm" or  "meters-ppm" are
     recommended.

-------
derivative absorption spectrum - a plot of rate of change of
    absorbance or of any  function of absorbance with respect to
    wavelength or any function, of wavelength.

double beam spectrum - a  transmission or absorbance spectrum
    derived by dividing the sample single beam spectrum by the
    background spectrum.

    Note:  The term "double-beam* is used elsewhere to denote a
    spectrum in which the sample and background interferograms
    are collected simultaneously along physically distinct
    absorption paths.  Here, the term denotes a spectrum in
    which the sample and  background interferograms are collected
    at different times along the same absorption path.

fast Fourier transform (FFT) - a method of speeding up the
    computation of a discrete FT by factoring the data into

    assembly or assemblies.

scaling - application of a multiplicative factor to the
    absorbance values in a spectrum.

single beam spectrum - Fourier-transformed interferogram,
    representing the detector response vs. wavenumber.

    Note:  The term  "single-beam" is used elsewhere to denote
    any spectrum in which the sample and background
    interferograms are recorded  on the same physical absorption
    path; such usage differentiates such spectra from those
    generated using  interferograms recorded along two physically
    distinct absorption paths  (see "double-beam spectrum"
    above).  Here, the term  applies  (for example) to the two
    spectra used directly in the calculation of transmission and
    absorbance spectra of a  sample.

standard reference material  - a  reference material,  the
    composition or properties of which are certified by a
    recognized standardizing agency or group.

    Note:  The equivalent ISO term is "certified reference
    material.•

    results  in  correctly interpolated points  in the computed

B. 1  General
    B.I.I  Assume a  fixed absorption pathlength equal to the
value Ls' .

    B.I.2  Use band  area calculations  to compare the relative
absorption strengths of the analytes and potential interferants.
In the me  analytical region  (FLn to FUJ , use either  rectangular'
or trapezoidal approximations to determine the band areas
described below  (see Reference A, Sections A.3.1 through A.3.3);
document any baseline corrections applied to  the spectra..

                     ESTIMATING NOISE LEVELS

C . 1  General

    C.I.I  The root -mean -square  (RMS) noise level is the
standard measure of noise in this Protocol.  The RMS noise level
of a contiguous segment of a spectrum is defined as the RMS
difference (RMSD) between the absorbance values which form the
segment and the mean value of that segment (see Appendix A) .

    C.I. 2   The RMS noise value  in double-beam absorbance
spectra is assumed to be inversely proportional to:  (a) the
square root of the signal integration period of the sample single
beam spectra from which it  is formed, and  (b) to the total
infrared power transmitted  through the interferometer and
absorption cell.

    C.I. 3  Practically, the assumption of  C.I. 2 allow the  RMS
noise level of a complete system to  be estimated from the
following four quantities:

     (a) RMS,,^ - the noise level  of  the system  (in absorbance
        units), without the absorption cell  and transfer  optics,
        under those  conditions  necessary to  yield  the specified
        minimum instrumental  linewidth.  e.g., Jacquinot stop
        size.

        twAN ~ the manufacturer's signal  integration time used to
        determine
     (c)  tss - the signal integration time for the analyses.

     (d)  TP - the manufacturer's estimate of the fraction of  the
         total infrared power transmitted by the absorption cell
         and transfer optics from the interferometer to the
         detector.


C.2  Calculation*

     C.2.1  Obtain the values of RMS^,  t^, and TP  from the
manufacturers of the equipment,  or  determine  the  noise level by
direct measurements  with  the completely constructed system
proposed in Section  4.

follows:
           RMSEST = RMS^ TP

B.1  General

    To estimate  the  reproducibility of  the  spectroscopic results
of the system, compare the CTS spectra  recorded before  and after
preparing the  reference spectra.  Compare the difference between
the spectra to their average band area.  Perform the calculation
for each analytical  region on the portions  of the CTS spectra
associated with  that analytical region.

B.2  Calculations

    E.2.1  The CTS spectra  {Rl} consist of  N spectra, denoted  by
Su, i=l, N.   Similarly,  the CTS spectra {R2} consist  of N
spectra, denoted by  S2i,  i=l, N.   Each Ski is the spectrum of a
single compound, where i  denotes  the compound and k denotes
the set {Rk} of  which Sxi  is a member.  Form the spectra S-,
according to S3i  = S2i-Su for each i.  Form  the spectra  S4

    E.2.2  Each  analytical  region m is  associated with  a portion
of the CTS spectra S2i and Su,  for a particular i,  with lower and

      DETERMINING FRACTIONAL CALIBRATION UNCERTAINTIES  (FCU)

F. 1  General

    F.I.I  The concentrations yielded by the computerized
analytical program applied to each single-compound reference
spectrum are defined as the indicated standard concentrations
(ISC's).  The ISC values for a single compound spectrum should
ideally equal the accepted standard concentration (ASC) for one
analyte or interferant, and should ideally be zero for all other
compounds.  Variations from these results are caused by errors in
the ASC values, variations from the Beer's law (or modified
Beer's law) model used to determine the concentrations, and noise
in the spectra.  When the first two effects dominate, the
systematic nature of the errors is often apparent; take steps to
correct them.                    '  •

    F.I.2  When  the calibration error appears non-systematic,
apply the following method to estimate  the fractional calibration
uncertainty  (FCU) for each compound.  The FCU is defined as the
mean  fractional error between the ASC and the ISC for all
reference spectra with non-zero ASC for that compound.  The FCU
for each compound shall be less than the required fractional
uncertainty specified in Section 4.1.

    F.I.3  The computerized  analytical  programs shall also be
required to yield acceptably low concentrations for compounds
with  ISC=0 when applied to the reference spectra.  The limits
chosen in this Protocol are that the ISC of each reference
spectrum for each analyte or interferant shall not exceed that
compound's minimum measurement uncertainty (MAU or MIU).


F.2   Calculation*

    F.2.1  Apply, each  analytical program to each reference
spectrum.  Prepare a similar table as that in Figure F.I to
present the ISC and ASC values for each analyte and interferant
in each reference spectrum.  Maintain the order of reference file
names and compounds employed in preparing Figure F.I.

    F.2.2  For all reference spectra  in Figure F.I, verify that
the absolute value of the ISC's are less than the compound's MAU
(for  analytes) or MIU  (for  interferants).

    F.2.3  For each analyte reference spectrum, calculate the
quantity  (ASC-ISC)/ASC.  For each analyte, calculate the mean of
these values  (the FCUi for the ich analyte)  over all reference
spectra.  Prepare a similar  table as that in Figure F.2 to
present the FCUj and analytical uncertainty limit (AUt) for each
analyte.

    The root-mean-square  (RMS) noise level is the standard

H.1  General

    Reference spectra  recorded at absorption pathlength  (LR) ,  gas
pressure (PR) ,  and gas absolute temperature (TR) may  be used to
determine analyte concentrations in samples whose spectra are
recorded at conditions different from that of the reference
spectra, i.e., at absorption pathlength  (Ls) ,  absolute
temperature (Ts) ,  and pressure (Ps) .   Appendix H describes the
calculations for estimating the fractional uncertainty (FAU) of
this practice.  It also describes the calculations for
determining the sample absorption pathlength from comparison of
CTS spectra, and for preparing spectra for further instrumental
and procedural checks.

    H.I.I  Before sampling, determine the  sample absorption
pathlength using least squares analysis.  Determine  the  ratio
LS/LR by comparing the  spectral sets  {Rl} and  {R3}, which are
recorded using the same CTS at L3 and LR, and Tg and TR, but  both
at PR.   '

    H.I.2  Determine  the  fractional  analysis uncertainty (FAU)
for each analyte by comparing a scaled CTS spectral  set,  recorded
at Ls,  Ts, and  Ps,  to the CTS reference spectra of the same gas,
recorded at LR,  TR, and PR.  Perform the quantitative comparison
after recording the sample  spectra, based on band areas  of the
spectra in the CTS absorbance band associated with each  analyte.

         DETERMINING FRACTIONAL MODEL UNCERTAINTIES  (FMU)


I . 1  General

    To prepare analytical programs  for FTIR analyses, the sample
constituents must first be assumed; the calculations in this
appendix, based upon a simulation of the sample spectrum, verify
the appropriateness of these assumptions.  The simulated spectra
consist of the sum of single compound reference spectra scaled to
represent their contributions  to the sample absorbance spectrum;
scaling factors are based on the indicated standard
concentrations (ISC) and measured  (sample) analyte and
interferant concentrations, the sample and reference absorption
pathlengths, and the sample and reference gas pressures.  No
band-shape correction for differences in the temperature of the
sample and reference spectra gases  is made; such errors are
included in the FMU estimate.  The  actual and simulated sample
spectra are quantitatively compared to determine the fractional
model uncertainty; this comparison  uses the reference spectra
band areas and residuals in the difference spectrum formed from
the actual and simulated sample spectra.

    The calculations in previous sections and appendices
estimate the measurement uncertainties for various FTIR
measurements.  The lowest possible overall concentration
uncertainty  (OCU) for an analyte is  its MAU value, which is an
estimate of the absolute concentration uncertainty when spectral
noise dominates the measurement error.  However,  if the product
of the largest fractional concentration uncertainty (FRU, FCU,
FAU, or FMU) and the measured concentration of an analyte exceeds
the MAU for the analyte, then the OCU is this product.  In
mathematical terms, set OFUi = MAXCFRUi, FCUt/ FAUL,  FMUJ and OCUt

                SPECTRAL DE-RESOLUTION PROCEDURES
K.I  General.
    High resolution reference spectra can be converted into
lower resolution standard spectra for use in quantitative
analysis of sample spectra.  This is accomplished by truncating
the number of data points in the original reference sample and
background interferograms.

    De-resolved spectra must meet the following requirements to
be used in quantitative analysis.

     (a) The resolution must match the instrument  sampling
resolution.  This is verified by comparing a de-resolved CTS
spectrum to a CTS spectrum measured on the sampling instrument.

     (b) The Fourier transformation  of truncated interferograms
(and their conversion to absorbance spectra) is performed using
the same apodization function (and other mathematical
corrections)  used in converting the sample interferograms into
absorbance spectra.


K.a  Procedure*

    This section details three alternative procedures using two
different commercially available software packages.  A similar
procedures using another software packages is acceptable if it is
based on truncation of the original reference interferograms and
the results are verified by Section K.3.

    K.2.1  KVB/Analect Software  Procedure - The following
example converts a 0.25 cm"1 100  ppm ethylene spectrum (cts0305a)
to 1 cm"1 resolution.  The  0.25 cm"1  CTS  spectrum was  collected
during the EPA reference spectrum program on March 5, 1992.  The
original data  (in this example) are-in KVB/Analect FX-70 format.

     (i)    decoop ct«0305a.aif,0305dr««,1,16384,1

     "decomp" converts cts0305a to an ASCII  file with name
0305dres.  The resulting ASCII interferogram file is truncated to
16384 data points.  Convert background interferogram
(bkg0305a.aif) to ASCII in the same way.

     (ii)   coopoae  0305dre«,0305dre».aif ,1

"Compose" transforms truncated interferograms back to spectral
format.

     (iii)  I02SP  0305dre«.aif,0305drea.d«f,3,l,low cm'1,high cm"1

     "IG2SP* converts  interferogram  to a  single beam  spectrum
using Norton-Beer medium apodization, 3, and no zero filling, 1.

-------
De-resolved interferograms should be transformed using the same
apodization and zero filling that will be used to collect sample
spectra.  Choose the desired low and high frequencies, in cm"1.
Transform the background interferogram in the same way.

     (iv)   DVDR 0305dres.dsf,bkg0305a.dflf,0305dres.dlf

     "DVDR" ratios the transformed sample spectrum against the
background.

     (v)    ABSB 0305dre0.dlf,0305dres.dlf

"ABSB" converts the spectrum to absorbance.

    The resolution of the resulting spectrum should be verified
by comparison to a CTS spectrum collected at the nominal
resolution.  Refer to Section K.3.

    K.2.2  Alternate KVB/Analect Procedure  —  In either DOS
(FX-70) or Windows version (FX-80) use the "Extract" command
directly on the interferogram.

     (i)    EXTRACT CTS0305a.aif,0305dre«.aif,1,16384

     "Extract" truncates the interferogram to data points from to
16384  (or number of data points for desired nominal resolution).
Truncate background interferogram in the same way.

     (ii)   Complete steps  (iii) to  (v) in Section K.2.1.

    K.2.3  Grams™ Software Procedure  - Grams™  is  a  software
package that displays and manipulates spectra from a variety of
instrument manufacturers.  This procedure assumes familiarity
with basic functions of Grams™.

    This procedure is specifically  for using Grams to truncate
and transform reference interferograms that have been imported
into Grams from the KVB/Analect format.  Table K-l shows data
files and parameter values that are used in the following
procedure.

    The choice of all parameters in the ICOMPUTE.AB call of step
3 below should be fixed to the shown values, with the exception
of the "Apodization' parameter.  This parameter should be set
(for both background and sample single beam conversions) to the
type of apodization function chosen for the de-resolved spectral
library.

K.3  Verification of New Resolution

    K.3.1  -Obtain iriterferograms of reference sample and
background spectra.  Truncate interferograms and convert to
absorbance spectra of desired nominal resolution.

    K.3.2    Document  the apodization function,  the level  of  zero
filling, the number of data points, and the nominal resolution of
the resulting de-resolved absorbance spectra.  Use the identical
apodization and level of zero filling when .collecting sample
spectra.

    K.3.3    Perform the same de-resolution procedure  on CTS
interferograms that correspond with the reference spectra
(reference CTS) to obtain de-resolved CTS standard spectra (CTS
standards).  Collect CTS spectra  using the sampling resolution
and the FTIR system to be used for the field measurements  (test
CTS).  If practical, use the same.pathlength,  temperature, and
standard concentration that were  used for the  reference CTS.
Verify, by the following procedure that CTS linewidths and
intensities are the same for the  CTS standards and the test CTS.

    K.3.4    After applying necessary temperature and  pathlength
corrections  (document these corrections), subtract the CTS
standard from the test CTS spectrum.  Measure  the RMSD in the
resulting subtracted spectrum in  the analytical region(s)  of the
CTS band(s).  Use the following equation to compare this RMSD to
the test CTS band area.  The ratio in equation 7 must be no
greater than 5 percent  (0.05).
