Project Summary
Response Factors of VOC
Analyzers Calibrated with
Methane for Selected
Organic Chemicals
G. E. Brown, D. A. DuBose, W. R. Phillips, and G. E. Harris
This report presents a summary of
the results of a laboratory study on the
sensitivity of portable Volatile Organic
Compound (VOC) analyzers to a vari-
ety of organic chemicals. This type of
analyzer is commonly used in monitor-
ing for fugitive emissions, with most
previous work having been done on
the Century Systems OVA-108, OVA-
128, or the J.W. Bacharach TLV Sniff-
er. The OVA-108 and the TLV were
chosen for testing in this study.
The sensitivity of the analyzer was
characterized by a response factor,
which was defined as the ratio of the
actual chemical concentration to the
observed instrument response. Bag
samples of known concentration were
prepared by introducing a measured
weight (or volume) of the subject
chemical into a Tedlar bag containing
a known volume of hydrocarbon-free
air.
Such response factors were deter-
mined for 168 organic chemicals at a
minimum of three concentrations.
These data points were fitted to a
predictive model to allow estimation
of the instrument response at any
concentration. This summary report
presents the coefficients of the predic-
tive equation for each chemical as well
as the fitted response factor at an
actual concentration of 10,000 parts
per million by volume (ppmv).
This Project Summary was devel-
oped by EPA's Industrial Environmen-
tal Research Laboratory in Research
Triangle Park, N.C. to announce key
findings of the research project that is
fully documented in a separate report
of the same title (see Project Report
ordering information at back).
Introduction
This report presents the results of a
laboratory study on the sensitivity of two
types of portable hydrocarbon detectors
to a variety of organic chemicals. The
introductory section briefly discusses
the background, objectives, and proce-
dures used in the project.
The study of fugitive VOC emissions
has rapidly gained emphasis over the
past several years. Several research
efforts designed to measure fugitive
emission levels and to assess the effec-
tiveness of proposed control schemes
are in various stages of completion. The
development of regulations to control
fugitive emissions has begun at both the
State and Federal level.
As a result of this research, a roughly
quantitative method for leak detection
has been developed which is commonly
called "screening." The screening
process is simply the measurement of
the VOC concentration at a point close
-------
to the potential leak site (valve stem,
pump seal, etc.). The measurement is
made with a portable VOC detector.
While many instruments could poten-
tially be used for this service, the bulkof
the existing data has been taken using
either the J. W. Bacharach "TLV Sniffer,"
the Century Systems "OVA-108," or
the "OVA-128."
While these instruments will respond
to almost any combustible material,
they exhibit different sensitivities to
various types of hydrocarbons and
substituted organic chemicals. The
"response factor" is a correction factor
which quantifies these differences in
sensitivity.
The primary objective of this work
was to experimentally determine the
response factors for a large number of
commonly encountered chemical spe-
cies. Such response factors are present-
ed here for both the OVA and the TLV.
Two instruments of each type (one old
and one new) were tested to check for
instrument-to-instrument variations.
Each chemical was tested at several
concentrations to assess variations in
the response factor over the range of
interest.
The experimental determination of a
response factor simply requires reading
the observed concentration on the
instrument when testing a gas sample
of known concentration. The response
factor is then calculated by:
Actual
Response JRPJ = Concentration
Factor Observed
Concentration
The standard gas samples were pre-
pared by one of two methods, depending
on the volatility of the subject chemical.
Liquids with low to medium volatility
were injected into a Tedlar bag contain-
ing a measured volume of hydrocarbon-
free air. The maximum concentration
tested was limited to 90 percent of the
saturated concentration at lab conditions
to prevent condensation or incomplete
vaporization. The chemical was injected
with a microliter syringe, which was
weighed before and after injection on an
electronic balance to get a precise
measure of the chemical introduced
into the bag.
Standard gas mixtures for gases and
highly volatile liquids were prepared
volumetrically. A cylinder of standard
gas was purchased at, or above, the
highest concentration to be tested.
Dilutions of this purchased gas with
zero air were made on a manifold with
the flows controlled by needle valves
and the flowrate of each gas measured
on bubble meters.
Response data were collected for 168
organic chemicals at a minimum of
three concentrations each. The response
factor of most of these chemicals varied
significantly with concentration, which
made it difficult to characterize the
response of a chemical with a single
figure. Accordingly, a correlation was
developed between response and actual
concentration that would estimate the
response at any concentration. This
predictive equation was used to generate
a table of estimated response factors at
10,000 ppmv, as shown in Table 1.
The user can generate estimates of
the response factor at any concentration
by the following equation:
Response Factor = C/IRC
IRC = exp (a + b • «hC + Se2/2)
where IRC is the instrument response to
a concentration of "C" ppmv, and "a,"
"b" and "Se" are constants given for
each chemical in Table 2 and Table 3 for
the OVA and TLV, respectively. The 95
percent confidence intervals bounding
this response factor estimate can be
calculated by:
and
(Cu) =
(CL) =
(IRC) + t
i (IRC) - t
S,RC
SIR°
where Cu is the upper confidence inter-
val, CL is the lower confidence interval, t
is the tabulated student's t with N-2
degrees of freedom for 95 percent
confidence, and
S,RC=
where Se, n, X, and SSx are constants
for each chemical given in Tables 2 and
3.
Conclusions
Response factors were determined al
a minimum of three concentrations foi
168 organic chemicals. The response
factors of most of these compounds
cannot be adequately represented by s
single number, as they vary significantly
with concentration. This report provides
estimates of the response factors at e
concentration of 10,000 ppmv, and a
correlation to estimate response factor:
for other concentrations of interest.
Recommendations
The complete document provides i
large body of data on the sensitivity o
response of VOC analyzers, but much
work is left to be done. All of the wor
reported here is on individual chemicals
yet such pure streams are rare in thi
industrial processes which will bi
surveyed for fugitive emissions. Data oi
the response characteristics of chemice
mixtures are essential to accurate fiel
measurements. Further work could als
be justified to try to develop a method t
predict the response factor of chemical
not yet tested based on their functions
groups and carbon numbers. This effoi
would probably be facilitated by th
development of a mechanistic, rathe
than an empirical, model of response.
