I. INTRODUCTION
This report summarizes the experimental procedures used,
and the data generated during the course of an investigation
of the exhaust emissions from several government furnished
vehicles. The work was performed by members of the
Functional Fluids R&D group of the Ag-Organics Department,
Dow Chemical USA under the terms of E.P.A. Contract #68-01-0480.
Each test vehicle was operated at 60 m.p.h. steady state
and under the conditions of the 23 minute Federal test
procedure (hot start) and the 41 minute Federal test pro-
cedure (cold start). Vehicle exhaust was monitored to
determine levels of emitted particulate matter including
mass-size distribution concentrations of particulate
associated trace metals, benzo-a-pyrene, sulfure and sulfate,
and levels of gaseous CO, NOx, unburned hydrocarbons,
ammonia and aldehydes.
All data generated is presented in the Appendix to this
report in the form that it was originally given to EPA at
the completion of each vehicle test series.
No attempt is made to draw conclusions from this study
because of the variety of different vehicles tested. It
is anticipated, however, that the data generated will be
of value to EPA in determining an overall emission profile
for the vehicles studied.

a)	60 m.p.h. steady state - 2 hour test run
b)	41 minute Federal test procedure (cold start)
c)	23 minute Federal test procedure (hot start)
2. Particulate Collection
Exhaust particles were collected after air dilution of the
exhaust in the large dilution tube described below. The
entire exhaust stream was fed into the dilution tube for
all tests conducted.
A. Dilution Tube (see Figure 1)
Air dilution and cooling of the exhaust was accomplished
by a dilution tube 16 inches in diameter and 27 feet in
length constructed of extruded polyvinyl chloride (PVC)
pipe in several sections with butt joints which were taped
during assembly prior to each run (Figure 1). The diluent
air coming into the tube was filtered by means of a Dri-Pak.
Series 1100 Class II PIN 114-110 020 untreated cotton filter
assembly. This filter assembly was 24" x 24" and had 36
filter socks which extended to 36 inches in length. This
filter will pass particles 0.3 u in size and smaller. Pres-
sure drop at 6 00 cfm flow rate is minimal. The flow rate of
dilution air in the tunnel was set at 550 cfm for all tests.
Exhaust was delivered to the tube via a tailpipe extension
which was brought into the bottom of the tube downstream
of the filter assembly. The extension was bent 90 degrees
inside the tube, thus allowing the introduction of the
exhaust stream parallel to the tube axis. Within the
dilution tube, along the perpendicular plane of the end
of the exhaust extension was a mixing baffle which has an
8-inch center hole and was attached to the inside diameter
of the tube. The baffle presented a restriction to the
incoming dilution air in the same plane as the end of the
exhaust extension and performed three essential functions.

a)	Provided a turbulent mixing zone of exhaust gas and
dilution air.
b)	Eliminated engine exhaust pulsations in the tube.
c)	Caused the tube to perform as a constant volume device
over a wide range of engine exhaust output volumes.
B. Sampling Devices
The particulate sampling zone for particles smaller than
15p was located at the exhaust end of the dilution tube.
Four isokinetic sample probe elbows were located in the
exhaust-air stream. One probe was connected to an Andersen
Impact Sampler Model 0203, a filter assembly, and a vacuum
pump, in that sequence. The probes were 0.754 inch ID stain-
less steel tubes which were located as shown in Figure 1.
A mercury manometer was connected between the dilution tube
probe and the exhaust side of the filter assembly, to mea-
sure the pressure drop across the filter. A flow meter was
used to monitor and regulate the flow through the Andersen
Sampler during the course of each run. Two sample probes
were both connected to 1 cfm Millipore filter holder (142
mm) _fitted with Gelman Type A glass fiber filter pads and
vacuum pumps. The fourth filter was a 47 mm, 1 cfm glass
fiber.
Prior to use, all the filters were stored in an instrument
room which is temperature- and humidity-controlled. The
filters were placed on the tray of the Mettler Analytical
Balance, allowed to reach equilibrium, and then weighed out
to 0.1 milligram (mg).
After the test, the filters were removed from the holders
and again allowed to reach equilibrium, noted by no further
change in weight, and then weighed to 0.1 mg. This was done
in the same room in which the papers were stored. The

-------
-7-
Millipore filter pads used were 142 mm Type AAWP 0.8y. The
fiber filter pads used were Gelman 0.3y Type A.
Andersen Sampler Model 0203 with a back-up 142 mm Millipore
filter was used as the basic particle collection device for
determining mass size distribution. Sample probes sized
to deliver an isokinetic sample from the dilution tube were
connected to the Andersen Sampler through which a proportional
sample was drawn at 1 cfm. The	cut-off values for the
Andersen stages are listed in Table 1. The D^q value is
the size at which 50% of those particles are collected,
while the remaining 50% pass on through to be collected on
the next stage.
Preweighed glass collection plates were used in this study.
Back-up filters were either Millipore Type AAWP 0.8y or
Gelman 0.3y Type A 14 2 mm diameter. Gelman glass fiber
filters were routinely used while the Millipore filters
were used for special analytical applications. Particulate
larger than 15y was evident as gravimetric fallout in the
dilution tube, but was not weighed or analyzed in this
study.

C. Condensate Collection
Exhaust gas condensate was collected for aldehyde and NH^
analyses. A tap was placed into the raw exhaust gas stream,
as close to the tailpipe of the vehicle as practical (about
12 inches). Raw exhaust was drawn through a three-stage cold
trap at the rate of 1 cfm. The cold trap consisted of
three flasks connected in series containing 40 grams each
of DI water, immersed in an ice water bath. The exhaust gas
flow bubbled through the water in the flasks. Condensate was
collected for 41 minutes during a Modified Federal Cycle Cold
Start, and for 23 minutes during a Federal Cycle Hot Start.
Sampling was terminated at ~25 minutes during steady-state
runs.
The condensate from the exhaust gas was analyzed for ppm of
HCHO and NH^. It was felt desirable to express this analysis
in volume percent to compare to the other components analyzed
in the exhaust gas. The procedure for this calculation is
as follows:
The "Ideal Gas Law" was used:	PV = n RT
v = n RT
P
The total liters of exhaust that was put through the con-
denser was known, the liters of the aldehyde can be calculated
from the formula above, so the volume percent can be calculated.
This volume percent is reported as volume parts per million
in the exhaust.

2. Exhaust Gases
Engine exhaust gases were analyzed routinely several times
during sampling runs. Schematically, exhaust gas sample
points were shown earlier in Figure 1. The engine exhaust
gas was analyzed for oxygen, nitrogen,,carbon monoxide,
carbon dioxide, and total unburned hydrocarbons. These
analyses were done by gas chromatography, chemical absorption,
and a total hydrocarbon analyzer. Data reduction was via
an IBM 1800 computer through a Bell Telephone ASR 33 Teletype
interface.
A. Hydrocarbons, CO, CC^, Nitrogen and Oxygen
Total unburned hydrocarbons were obtained from a Beckman
Model 109A FID Total Hydrocarbon Analyzer. A Fisher Gas
Partitioner was used for the analysis of oxygen, nitrogen,
carbon monoxide, and carbon dioxide. The partition column
consisted of a 6-foot section containing hexamethyl phos-
phoramide and a 6 1/2-foot section containing 13x molecular
sieves in series.
The output of the gas chromatograph was coupled with a
Hewlett-Packard Model 3370A Digital Intergrator which has
an ASCII coded output to drive an ASR 33 Teletype and punch
paper tape.
Sampling
A Neptune Dyna-Pump was used to draw the sample from the
exhaust pipe sampling point through 1/4" OD stainless steel
tubing and transfer it to the total hydrocarbon analyzer
and the gas sampling valve of the gas chromatograph through
1/8" OD stainless steel tubing. A manifold system was pro-
vided to allow the operator to calibrate the equipment with
the appropriate standards.

-------
-11-
Standardization
A gas mixture containing known concentrations of oxygen,
nitrogen, argon, carbon monoxide, carbon dioxide, and
n-hexane was used as a reference standard for the total
hydrocarbon analyzer and the Fisher Gas Partitioner.
Operation
The operator typed the proper computer code and program num-
ber on the teletypewriter, injected the reference standard,
and pressed the integrator start button. As the peaks emerged,
the time and area information was encoded and stored on punched
paper tape. Each succeeding exhaust gas was identified along
with the total hydrocarbon level, and run in the same manner
as the standard. When the series was finished, the punched
tape was sent to the computer by teletype over regular tele-
phone lines.
Data Reduction
A typical output format for the gas analysis is shown in
Figure 2. Identification of the components in the standard
was based upon each peak size in descending order. Estimated
retention time was the updated time of each peak in the
standard. Retention time windows were 4 seconds plus 2
percent of the retention time. Actual percent was a direct
ratio of the area counts in the unknown sample to the area
counts in the standard times the volume percent in the
standard. The total percent actual is normally 97-98 per-
cent since water is removed from the saturated sample after
the sampling valve.
A correction for the unresolved argon in oxygen was made
based upon response factors and the amount of argon found
in a number of exhaust gas samples by mass spectroscopy.

-------
-12-
The actual percent was normalized to 100 percent in the
next column on a moisture free basis, and an Exhaust Gas
Analysis report was issued (Figure 2). The air-to-fuel
ratio was calculated from this analysis, the total hydro-
carbon content, and the percent carbon in the fuel.
B. Oxides of Nitrogen
Equipment
a.	Prototype built by EPA of Research Triangle Park, N.C.
b.	Model A Thermo Electron Unit.
Calibrating Gases
a.	Zero air nitric oxide, 51 ppm and 208 ppm.
b.	These standard gases were purchased from Scott Research
Inc.
c.	Nitrogen was used as zero calibrating gas.
Procedure
a. Before making N0-N02 measurements the instrument was
warmed up. Flow through the loop was balanced according to
the operating procedures described in a report "A Method for
Analysis of Oxides of Nitrogen (NO, N02) in Auto Exhaust"
by John Sigsby, Frank Black, Tom Bellar, and Don Klosterman
of EPA.
The instrument was calibrated as described in the above
report. The zero standardizing was done using zero air and
the up-scale calibration was done using a series of cali-
brating gases with varying levels of NO.
After calibration, the auto exhaust gases were passed through
the analyzer at the same flow rate as used during standardi-
zation. The NO and NO values were read from a digital
x	*
read out meter and recorded.

b. As in the prior procedure, the Thermal Electron Model A
analyzer was standardized as prescribed by the manufacturer.
After calibration, the exhaust gases were passed through at
the same flow as used during the standardization and the
values in ppm of NO and NO were read from the indicating
X
meter and recorded.
3. Exhaust Particles
The collection and classification techniques employed allowed
the calculation of mass emission rates in grams/mile of
exhaust particulate. Additionally, cumulative mass distri-
bution data can be calculated. The specific techniques for
chemical analysis of particulate matter follow:
A. Carbon and Hydrogen
The percentage of carbon and hydrogen in the particulate
was determined by pyrolysis and collection of the combustion
products. An entire 142 mm glass fiber filter containing
the particulate was placed in a large platinum boat. The
boat was then transferred to a combustion tube, and the
sample was combusted at 1100C for 3/4 hour. Carbon dioxide
i
and water were absorbed in micro absorption tubes and weighed
in the conventional manner. The C and H values were then
calculated from the increase in weight using the given weight
of the particulate.
In general, this technique is quite accurate for carbon and
hydrogen analysis. However, the small sample sizes generated
in a 23-minute cycle make it difficult to obtain precise
results. The inherent inaccuracy of weighings (even using
a 5-place balance) plus the large blank size make the results
of a small sample only meaningful in a gross comparative
sense.

-------
-15-
B. Benzo-g-pyrene
Samples of exhaust particulate were collected on Gelman
142 mm glass fiber filter pads in a Millipore filter holder
operating at 1 cfm. The samples on the glass filter pads
were analyzed for benzo-a-pyrene in the following manner.
When available a sample of at least 10 mg (on either one or
two filter papers) was used for analysis. The filters were
folded and rolled with the particulates toward the inside
of the roll and tied with copper wire. The rolls were
Soxhlet extracted for at least 6 hours (with siphoning four
to six times per hour) with 7 5 ml of benzene. The extracts
were evaporated under a stream of filtered air at room
temperature to approximately 3 ml. This concentrate was
filtered through a M-fritted glass filter into a tared vial.
The flask and filter were washed three times with approxi-
mately 2 ml of benzene for each wash. The combined filtrates
were evaporated to dryness at room temperature with a stream
of filtered air.
The .residues obtained from both sample and blank filters
were weighed and the difference between them designated
"benzene soluble weight" for each sample. The residue was
dissolved in 0.2 ml of methylene chloride and a 10-40 yl
aliquot was spotted in 2 yl increments on a pre-conditioned
Alumina TLC plate along with a known standard of benzo-a-
pyrene in methylene chloride. The TLC plates were condi-
tioned by heating at 120C for 1.5 hours and desiccating
overnight in a 45 percent relative humidity chamber (satu-
rated aqueous zinc nitrate). The TLC plate was developed in
an unsaturated tank containing 20 ml of ethyl ether in 200 ml
of n-pentane to a height of 15 cm (approximately 45 minutes).

-------
-16-
The benzo-a-pyrene spots were identified by comparison of
's with that of the standard spot under an ultraviolet
lamp. The spots, marked with a pencil, were circumscribed
with a #15 cork borer and scraped from the plate into vials.
All TLC work was performed as much as possible in a dimly
lighted area to avoid decomposition of the benzo-a-pyrene.
Five ml of 5 percent acetone in n-pentane was added to the
alumina in the vial and it was agitated for 15 minutes on a
mechanical shaker. The slurry was filtered through a F
sintered glass filter into a vial, washing the alumina four
times with approximately 2 ml of 5 percent acetone in n-pentane
with a 45-second soak period between each wash. The com-
bined filtrates were evaporated to dryness at room temperature
using a stream of filtered air. The benzo-a-pyrene residue
was taken up in 2.0 ml of concentrated sulfuric acid. This
solution was evacuated for five minutes to remove trapped
air bubbles and its fluorescence was measured in a one-cm
cell at 54 0 nm while exciting at 470 nm on an Amino-Bowman
Spectrophotofluorometer using a #4 slit arrangement and a
sensitivity of 30.
Standard and blanks were carried through the entire TLC
procedure. The blanks were subtracted from all fluorescence
readings and the net fluorescence values for each sample
were used to calculate the amount of benzo-a-pyrene present.
Throughout all steps in the procedure the samples were
refrigerated when not actually being processed and exposure
of the samples to light was kept at a minimum.
C. Trace Metals
Emission spectrometry (ES) and x-ray fluorescence were used
for determination of metals in the particulate. Trace metals
were determined by ES on Millipore filters while lead was
determined as a percent of the particulate collected on
the 142 mm, 1 cfm fiberglass filter.

Emission Spectrometry
a.	Principle
Organic matter in the sample was destroyed by wet ashing in
sulfuric, nitric and perchloric acids. The resulting solu-
tion was taken to dryness and the resi.due taken up in a
spectroscopic buffer solution containing the internal refer-
ence element, palladium. A portion of the solution was dried
on pure graphite electrodes. The electrodes thus prepared
were excited in an a.c. arc discharge and the spectrum is
photographed. The intensity ratios of selected lines were
determined photometrically and the concentration of each
element read from an analytical curve relating intensity
ratio to concentration.
b.	Apparatus
1.	Excitation - Excitation was obtained by the use of a
2400 volt a.c. arc discharge, Jarrel-Ash Custom Varisource
or equivalent.
2.	Spectrograph - Baird 3 meter grating spectrograph.
Reciprocal dispersion was 5.55 A/mm in the first order.
3.	Developing equipment - Jarrel-Ash Company. Plates were
developed in a thermostatically controlled developing machine,
washed and dried over heat in a stream of air.
4.	Densitometer - Spectral lines were measured with a non-
recording projection-type densitometer. Densitometer Com-
parator, Baird Associates Inc.
5.	Calculating equipment - A calculating board was employed
to convert densitometer readings to log intensity ratios.

6. Wet ashing equipment - A micro Kjeldahl digestion rack
was used for wet ashing the organic solvents.
c.	Reagents and Materials
1.	Distilled nitric and perchloric ac.ids. Perchloric acid
is an intense oxidizing agent. Organic matter should not
be heated in perchloric acid unless in the presence of sul-
furic or nitric acid.
2.	Sodium nitrate, reagent grade (NaNO^)
3.	Palladium diamine nitrite, PdtNH^^ (NC^^-
4.	Water soluble salts of the elements Al, Ca, Cu, Fe, Mg,
Mn, Ni, Pb, Sn, and Zn.
5.	Electrodes, high purity graphite, 1/4" diameter by
3/4" length. Ultra Carbon Corporation.
6.	Photographic plates - Eastman Spectrum Analysis No. 3.
7.	Kjeldahl flasks, 10-ml.
d.	Calibration
1.	0.2182 gm of palladium diamine nitrite Pd(NH^)22
were dissolved in water. Ten ml of concentrated reagent
grade nitric acid were added and the mixture diluted to
volume with water in a 100 ml volumetric flask. This solu-
tion contains 1 mg Pd per ml.
2.	A buffer solution was prepared by dissolving 20 gm of
sodium nitrate in water. 5.0 ml of the palladium solution
above and 7.5 ml of concentrated reagent grade nitric acid
were added and the whole diluted to 100 ml.

-------
-19-
3.	A stock solution containing 0.01% (0.1 mg/ml) each of
the elements Al, Ca, Cu, Fe, Mg, Mn, Ni, Pb, Sn, and Zn was
prepared. Two aliquots of this solution were diluted ten-
fold and one hundred-fold to provide 0.001% and 0.0001%
solutions.
4.	Standard additions of the impurity elements were made
to Kjeldahl flasks as shown in Table 3.
5.	0.5 ml of concentrated reagent grade sulfuric acid was
added to the Kjeldahl flasks and the solution evaporated
to dryness. After cooling, 1 ml of concentrated nitric acid
was added and the mixture was evaporated to dryness again.
The residue was taken up in 5 ml of buffer solution, warming,
if necessary, to put the salts into solution.
6.	The end of the 3/4" graphite electrodes was polished
on filter paper and placed in a stainless steel drying tray.
A drop of kerosene was placed on the top of each electrode
to seal the porosity and the electrode allowed to dry. One
pair of electrodes was prepared for each of the standard
addition solutions by pipetting 0.03 ml of the solution onto
the end of each electrode. The electrodes were dried slowly
over micro burners in a gas drying oven and stored in a
desiccator until run.
7.	The samples were excited in water-cooled electrode
holders using the following conditions:
a)	Current, 4.0 amps, a.c. arc.
b)	Spectral region, 2150-3550A.
c)	Slit width, 50 p.
d)	Electrode gap, 2 mm.

-------
-20-
e)	Pre-burn period, 10 seconds.
f)	Exposure period, 90 seconds.
8.	The emulsion was calibrated by use of a stepped filter
or by other recommended methods described in the "Recommended
Practice of Photographic Photometry in Spectrochemical Ana-
lysis" A.S.T.M. designation: E116, Methods for Emission
Spectrochemical Analysis, (1964).
9.	The emulsion was processed according to the following
conditons.
a)	Developer (D19, 20.5C), 3 1/2 minutes.
b)	Stop bath (SB-4), 1 minute.
c)	Fixing bath (Kodak Rapid Fixer), 2 minutes.
d)	Washing, 3 minutes.
e)	Drying, in a stream of warm air.
10.	The relevant analytical line pairs were selected from
Table 4. The relative transmittances of the internal stand-
ard line and each analytical line were measured with a
densitometer. The transmittance measurements of the analyti-
cal line pairs were converted to intensity ratios by the use
of an emulsion calibration curve and a calculating board.
11.	Analytical curves were constructed by plotting concen-
tration as a function of intensity ratio on log-log graph
paper. For best results, the average of at least four
determinations recorded on two plates were plotted.
e. Procedure
The available sample was weighed directly into a Kjeldahl
flask. Wet oxidation was carried out with nitric and per-
chloric acid only. Extreme caution was exercised in the use

of this technique. Concentrated nitric acid was added
dropwise, a few tenths ml at a time, to the hot mixture to
aid in oxidation. A few drops of concentrated perchloric
acid may be added to the hot solution after most of the free
carbon has been destroyed, to hasten complete oxidation.
When the solution became water clear, it was evaporated to
dryness. After cooling, 0.5 ml of nitric acid was added
and the mixture evaporated to dryness. The addition of 0.5
ml of nitric acid was repeated and the solution evaporated
to dryness again. The inorganic residue was dissolved in
dilute nitric acid and the volume adjusted to a known concen-
tration, usually 10 mg/ml. If the original sample size was
below 30 mg, a less concentrated solution was usually made
up. Aliquots of this solution were taken to dryness and
then the buffer solution (d2) added in an amount to give a
dilution factor of lOOx. One sample was analyzed by the
direct reader while a second was examined photographically.
Some samples had to be run at factors larger than lOOx in
order to get the concentration for some elements to fall
within the range of the analytical curves. By varying the
sample to buffer ratio any number of concentration or
dilution factors could be achieved. A blank of the acids
used was carried through in the same manner as the sample.
f.	Calculations
The intensity ratios were converted to concentration by
use of the analytical curve.
g.	Precision and Accuracy
Representative precision and accuracy of the method are
given in Table 5. Each of the twelve samples A^,	A^,

Induced Electron Emissions
The samples were analyzed for sulfur using IEE (Induced
Electron Emission, also known as ESCA "Electron Spectro-
scopy for Chemical Analysis"). In this method of analysis,
the sample was irradiated with x-rays, which produce photo-
electrons, the energies of which are dependent on the
elements present and the valence states of the elements.
The electrons are energy analyzed and counted.
The electron spectrons were measured using a Varian IEE-15
spectrometer. The region of the electron spectrum con-
taining the sulfur 2p line (binding energies from 159 e.v.
to 179 e.v.) was scanned for a total of 1000 seconds (100
ten second scans), using an x-ray power of 1 KW and an
analyzer voltage of 100V, for maximum sensitivity.
Standard Sample Handling: A piece .75" by 1.18" was cut
from the center of each filter and mounted on a 3/8"
diameter by 3/4" long aluminum cylinder with double-stick
scotch tape.

-------
-25-
X-Ray Fluorescence
The samples were received on filter discs measuring 3.5 cm
in diameter. Weight of the samples ranged from 25 mg to
0.3 mg. Due to the small mass of sample on the discs,
data measurements and interpretation was approached with
the idea that each element of interest present on the discs
was as an infinitely thin sample. An infinitely thin sample
is a sample containing the element of interest only on the
surface of the bulk material and having a mass/area concen-
tration less than the experimental relationship of 0.1/p/p
(regult in g/cm ); p/p being the total mass absorption co-
efficient of the sample with respect to the element of
interest. Usually y/p is the mass absorption of the major
element present in the bulk matrice; carbon in the case of
the filter disc, unless large amounts of some metal are
present on the filter disc. Having an infinitely thin
sample, direct comparison may be made on the amount of sur-
face mass "without taking in account matrices effects, greatly
simplifying the data interpretation.
The samples were analyzed by wavelength dispersive x-ray
fludrescence, using a Norelco Philips spectrometer and
associated electronics, at an operating voltage of 50 kilo-
volts and current of 20 milliamps. A tungsten x-ray tube,
LiF crystal, and Nal scintillation detector were used for
the Pt, Pd, Ni, Cu analysis, while a chromium x-ray tube,
EDDT crystal (ethylene diamine d-tartrate) crystal, and
proportional flow counter was used for the sulfur analysis.
For each element analyzed, the radiation was scanned
and measured. Net peak heights for each element were com-
pared with known infinitely thin standards of Pt, S, Ni,
Cu and Pd. In the case where the samples turned out not
to infinitely thin, infinitely thick standards were used
for the comparison with corrections made for sample size
and matrice.

Turbidimetric Determination of Inorganic Sulfate
a.	Scope
The method is applicable to the determination of 1 to 10
mg of Na^SO^j. See Note 10(a) for types of samples which
can be analyzed.
b.	Principle
An acid solution of the sample is treated with a barium
chloride-gelatin solution and the resulting turbidity is
measured on a spectrophotometer.
c.	Interferences
The interferences would be those which cause a turbidity
in the solution that could not be filtered prior to adding
the gelatin mixture, by highly colored solutions and those
which would normally be encountered in gravimetric analysis.
d.	Safety Precautions
Use caution when handling concentrated acids and wear
appropriate safety equipment.
e.	Apparatus
Klett-Summerson colorimeter equipped with a No. 40 filter
and a 4-cm cell, or a Dow Diagnostest colorimeter equipped
with a 420 nm filter and a digital read-out concentration
meter.
f.	Reagents
1.	Hydrochloric acid (1:1) . Carefully mix equal volumes
of concentrated hydrochloric acid and distilled water.
2.	Barium chloride-gelatin mixture. Heat about 9 00 ml
of distilled water to boiling and transfer the beaker to
a steam bath. Add 25 grams of purified calfskin gelatin

-------
-27-
to the beaker and heat and stir until the gelatin is
dissolved- Add 100 grams of reagent grade barium chloride
dihydrate to the beaXer and dissolve. Cool and dilute to
1000 ml. Add 3 crystals of Thymol as a preservative. See
Note 10 (b) -
3. Sodiu^i sulfate solution/ 1 ml = 1 mg Na^sO^  Dissolve
1.000 gram of anhydrous sodium sulfate in water and dilute
to 1 liter.
g.	Preparation of Calibration Curve
1.	Transfer 0.0, 1.0, 2.0, 4.0, 6.0, 8.0, and 10.10 ml
of sodium sulfate standard solution (1 ml = 1 mg Na^SO^)
into lOO^ml volumetric flasks, add 1.0 ml of 1 to 1 hydro-
chloric acid solution, dilute to about 50 mis, add 2.0 ml
of barium chloride-gelatin solution and dilute to volume.
Mix well and let stand for 5 minutes.
2.	Sera the instrument on distilled water and obtain
readings on the blank and standard solutions. Subtract the
blank solution reading from the others and plot the readings
vs. concentration on graph paper. see Note 10(c).
h.	Procedure
1. Pipet a clear solution of the sample which contains
from 2.0 to 10 mg of sodium sulfate into a 100-ml volumetric
flask. see Notes 10(e), (f), and (g). Add 1 drop of
phenolphthalein solution, neutralize with 1 to 1 hydrochloric
acid solution and add 1 ml in excess. Dilute to about 50
mis, add 2.0 mis of barium chloride-gelatin solution and
dilute to volume. Mix well and let stand for 5 minutes.
See Note 10(d). prepare a blank usinq 1 ml of 1 to 1 hydro-
chloric acid and 2.0 ml of barium chloride-gelatin solution
in 100 ml.

-------
-28-
2. Zero the instrument on distilled water and read the
blank and sample solutions. Subtract the blank reading
from the sample reading and obtain the mg of sodium sulfate
from the calibration curve.
i. Calculation
% Na2S04 =	mg Na2S04
10 x grams of sample
j. Notes
1.	Samples that have been analyzed successfully are brine,
salt samples, 10% caustic samples, aqueous samples, and
Dowfax type materials after extraction.
2.	The gelatin solution is stable for at least three
months.
3.	The curve is reproducible but should be checked occasion-
ally. A new curve should be prepared for each new batch of
gela,tin.
4.	The solutions are stable for at least 30 minutes.
5. For greatest accuracy in determining low amounts of
sulfate in high amounts of other salts, standards should be
prepared from solutions containing equal amounts of these
salts.
6. Acidity appears to be very important in determining low
amounts (1 mg and less) of sodium sulfate. Therefore,
neutralize with 1 to 1 hydrochloric acid to phenolphthalein
and add only one or two drops in excess before adding the
barium chloride-gelatin mixture.

-------
-29-
7. Not more than 5 grams of 50% sodium hydroxide should
be used for analysis. 2.5 grams of 100% or 73% caustic
may be used. Prepare a curve with an equivalent amount
of ACS reagent grade caustic.
k. Precision and Accuracy
The method can be expected to yield results which are
accurate to within 1 to 2 percent relative error. Samples
analyzed gravimetrically and turbidimetrically agreed to
within 1%. Duplicate samples agreed to within 1%.
D. Condensate Analyses
Condensate was collected from the raw exhaust as described
earlier. The condensate was analyzed for aldehydes and
NH^ using the procedures outlined below.
Aldehydes
The analytical method for the determination of carbonyl
compounds in automotive exhaust emissions employed polaro-
graphic techniques. Samples for analysis were collected
from, undiluted exhaust effluent using ice-water cooled
cold traps and via a sample probe welded into the engine
or vehicle exhaust system.
The theory for the polarographic analysis of auto exhaust
condensate is described in detail in an EPA Report APTD 1567
dated March 1973 and is not included in this report. Since
that time a portable hanging drop polarograph was developed
by J. D. McLean and J. F. Holland of Dow Chemical Co. and
was used for all determinations covered in this report.
The procedure for the aldehyde measurements was as follows:

-------
-30-
Procedure
For a typical sample analysis, 0.1 ml of exhaust condensate
was pipetted into a clean, dry 10-ml volumetric flask. Five
ml of pH 4 buffer acetate and 1 ml of aqueous hydrazine
solution were added and then enough DI water was added to
make 10 ml. The preceeding mixture was shaken well and then
transferred to a clean, dry polarographic cell and deaerated
with oxygen-free nitrogen for 5 min. The nitrogen sparger
was lifted above the liquid level in the cell and a nitrogen
blanket was maintained over the sample during scanning. The
electrodes were inspected for trapped air which was removed.
A mercury drop was hung by turning the micrometer knob of
the hanging drop electrode. The first droplet was always
discarded and a new drop formed using a prescribed number of
micrometer units. The number of units for droplet formation
was kept constant. The polarograph was turned on and the
up-scale deflections shown on the digital read-out meter
were recorded. This measurement was made 3 times for each
sample with a fresh mercury drop.
The cell was lowered and 0.1 ml of HCHO (known concentration)
was 'added. The cell was again deaerated as before and a
mercury droplet was formed as before and 3 scans were made.
To correct for the effect of the reagents alone, a blank
was always run to establish the meter up-scale deflection.
These values were substracted from the values obtained
during the scanning of the condensate sample which were
then used for calculation.

b. Ammonia
Ammonia is present in the exhaust gas condensate and is
analyzed in the following manner.
A 5-10 cc aliquot of condensate is added to a 50 percent
potassium hydroxide solution. This mixture is then steam
distilled into an excess of 0.010 N hydrochloric acid.
The excess acid is determined by adding potassium iodide
and iodate and titrating the liberated iodine with 0.010 N
sodium thiosulfate.
This technique is capable of determining ammonia as low
as 0.3 ppm. Figure 3 is a sketch of the apparatus used
for the determination.
The analytical procedures given herein have been adapted
from literature sources or developed upon the basis of
experimental data which are believed to be reliable. In
the hands of a qualified analyst they are expected to
yield results of sufficient accuracy for their intended
purposes. However, The Dow Chemical Company makes no
representation or warranty whatsoever concerning the pro-
cedures or results to be obtained and assumes no liability
in connection with their use. Users are cautioned to
confirm the suitability of the methods by appropriate
tests.

diesel samples are possible because the diesel exhaust fouls
the equipment. Nitrogen was not tested for in the particulate.

VEHICLE TEST REPORT # 5
Date of test: 7-18-73
Vehicle: EPA William's Gas Turbine
Test Conditions:
Barometer	29.60
Wet Bulb	65.0F
Dry Bulb	71.5F
Rel. Humidity	49%
Procedures:
Modified Fed. Cold Start 41 Min.
Federal Cycle Hot Start 23 Min- (2)
1 Hr. SS 50 MPH Hot Start
Comments:
Only 1/2 engine exhaust was used. A 5" SS flexible tube was
used to couple exhaust pipe to exhaust inlet to dilution tube.
There was a possibility of exhaust leakage in the exhaust adapter
which was installed by the EPA people upon arrival. The fuel tank
had to be vented using a 20'1/4" rubber tube due to excess heating
of fuel tank with" exhaust adapters. Steady state run was made at
50 MPH for only 1 hr. due to the fuel tank heating problem.
Had fire department stand by during entire testing period.
NOTE: Could not maintain a 4 CFM flow through the millipore
47MM filtet for the duration of each test.

Comments:
This car was brought up on a trailer. The vehicle was a
front wheel drive Audi Fox equipped with fuel injection
EGR, special spark plugs and catalytic converter. It had
a, 4 speed transmission and radial ply tires. The humidity
was very high and there was some doubt whether a reliable
test could be lnade. There was no moisture detected in the
rotameters during the test period. The humidity monitor at
the sampling zone read very high during all phases of the
tests. Due to the tight schedule for the car, it could not
be held over to run on the following day. Two representatives
ied the car and observed the

Comments:
The vehicle was driven up from DuPont by Mr. G. W. Kunz' wh
stayed to observe the setting up and the first day of testing.
Because of the high humidity, the tests could not be completed
while he was here. The fuel, a special lead blend, was
supplied by Ann"Arbor EPA as was the driving cycle promptor.
The dilution flow was 550 CFM at 420 F/min velocity. The
particulate was sampled at 1 CFM.
