Analysis of odors in vehicle cabins
and prediction of related VOC concentrations
Koichiro Iwai
In recent years, the comfortableness has become a significant factor in
development of automobile. The odor in vehicle cabin is the first contacting
factor when a user gets in a car. Therefore, it is considered that the odor in
vehicle cabin should be preferable. Odor is composed of many odorous
compounds, which might be emitted from interior parts and/or be introduced
by user with food and body odor, etc. In this dissertation, in order to improve
the conditions in vehicle cabins, we developed fundamental technologies for
the analysis and assessment of complex odors and prediction of the
concentrations of the related volatile organic compounds (VOC) emitted from
vehicle parts. Firstly, we tried to develop the optimization testing method of
thermal
desorption-gas
chromatography-mass
spectrometry/olfactometry
(TD-GC-MS/O) which is the useful analytical instrument to specify the
odorous compounds in the complex odor. After that, highly-sensitive
measurement method of short-chain fatty acids using a detector tube is
discussed. Short-chain fatty acids are the significant compounds of the odor in
in-use automobile. In this study, odor from the livestock excretion is addressed
as the model odor sample. Finally, we studied a method to predict the
concentrations of odorous compounds in vehicle cabins based on the
relationship between obtained and predicted values for different methods of
evaluation. Focusing on the VOC as the model of odor compounds, a novel
method for prediction, called the labeled compound addition method was
developed.

Chapter 1 briefly describes the odors in vehicle cabins. First, the olfactory
receptive mechanism and the feature of a smelling sense such as the
relationship between the concentration of odorous compounds and odor
intensity are stated. Then, typical methods for evaluating odors in vehicle odor,
e.g. sensory evaluation method, detector tube method and instrumental
analysis including TD-GC-MS/O are discussed. In addition, general tendencies
in the concentrations of the odor compounds in vehicle cabins are also
described. Focusing on the VOC as the model of odor compounds, the efforts
to reduce the VOC concentration in vehicle cabins in Japan and the other
nations are reviewed. Finally, the objectives of this study are explained.
In Chapter 2, GC-MS/O optimization testing method is described.
TD-GC-MS/O is a useful method to specify the odorous compounds in the
complex odor. However, a number of odorous compounds are chemically
unstable and adsorptive, odor quality often changes by thermal decomposition,
oxidation and/or adsorption of the odorous compounds in multistep analytical
procedures. In this work, to minimize the change in odor quality, 3 steps of
test methods were examined; Test 1: Determination of the most appropriate
temperature at the thermal desorption process, Test 2: Confirmation of optimal
analytical conditions of TD-GC-MS/O, and Test 3: Verification of the detected
odors in TD-GC-MS/O analysis. To achieve these test methods, the specific
odor of new Tenax TA (2.6-diphenyl-p-phenylene oxide) porous polymer
beads produced by heating at 280 ºC (Tenax TA odor) was used. Both the most
appropriate temperature at the thermal desorption process and the maximum
temperature in the instrument were estimated to be 250 ºC by Test 1 and 2.
Under the optimized conditions, twelve element odor compounds in Tenax TA
odor were specified by three panels using TD-GC-MS/O, among which seven
odor
compounds

identified

These

demonstrated that the 3 steps of the proposed test methods were suitable for
the optimization of TD-GC-MS/O analytical conditions.
In Chapter 3, highly-sensitive measurement method of short-chain fatty
acids was discussed. Short-chain fatty acids (especially C4 and C5) are
involved in the critical components of the odor from the livestock excretion.
However, the concentrations of the short-chain fatty acids are often too low to
analyze even when it strongly smells. In this work, a highly-sensitive
measurement method of short-chain fatty acids was developed using detector
tube. In this method the short-chain fatty acids were concentrated in the
adsorbent prior to the detector tube measurement. In this experiment, four
kinds of adsorbents, Tenax TA (60/80 mesh), multi-bed carbon (carbopack B
and carbopack C; 60/80 mesh, respectively), carbopack Y (graphitezed carbon
black; 60/80 mesh), carbopack F (graphitezed carbon black; 60/80mesh) and
quarts powder, were tested. Then it was verified that quarts powder was the
most suitable adsorbent for this method, which also made it possible to use the
circumambient air for the carrier gas of the thermal desorption from the
adsorbent. The temperature fluctuation and the condensation of the water
vapor were compensated by installing the U-tube between adsorbent and a
detector tube. The influence of the interferential species was negligible in this
method mainly because of their irreversible adsorption on the quartz adsorbent.
Finally it was demonstrated that the concentration of short-chain fatty acids
were able to be determined in the headspace gas from composting pig dung.
In Chapter 4, a method for predicting the concentration of odor
compounds in vehicle cabins was studied with considering VOC as the
representative of odor compounds. In Japan, the Japan Automobile
Manufacturers Association, Inc. (JAMA) announced voluntary guidelines in
vehicle cabin for the concentrations of 13 types of VOC in 2005. Vehicle cabin

VOC concentrations are officially evaluated using a defined method (e.g., the
JAMA method), but those in small size of parts (e.g., test pieces (TP),
assembly parts) are often evaluated by other methods (e.g., sampling bag
method (bag method), chamber method) depending on the type and the size of
sample. Therefore, the parameters in evaluation including sample size, amount
of gas, and ventilation frequency vary according to the method used. Owing to
these variable conditions, it is difficult to predict VOC concentration in
vehicle cabin from the evaluated VOC values of component parts. To address
this, we have studied the relationship between obtained and predicted values
of the VOC concentrations for different methods of evaluation. In this chapter,
we present the results for measurement of toluene using the bag method.
As a first step, we investigated the effect of evaluation condition (heating
time, sample size, gas volume, and heating temperature) to the toluene
concentration. As a result, the following four points were found, 1) a toluene
concentration reaches a stable level after 4.5 h, which corresponds the heating
period for a standard measurement method, 2) the amount of volatilized
toluene is not proportional to the number of samples in the bag, 3) the amount
of volatilized toluene increases with increasing the gas volume in the bag, and
4) the amount of volatilized toluene increases with rising the heating
temperature.
On the basis of these results, we assumed that the VOC emitted from a
new sample (RG) can be described by the VOC contained in the new sample
(RA) and adsorptive capacity (K) of the parts when the VOC concentration in
the bag reaches equilibrium. We defined K as the proportion of adsorbed
amount of VOC in the sample (RS) to emitted amount of VOC from the sample
(RG). RA can be thus expressed as the sum of RS and RG. Then, we developed
a novel method, called the labeled compound addition method, incorporating a
iv
㻭㼎㼟㼠㼞㼍㼏㼠
labeled compound to predict RA and K. In this method, we added a specific
amount of a labeled compound (e.g., deuterium-labeled VOC) (RA’) with
entering nitrogen gas the bag. The labeled compound should behave similarly
to VOC in the bag. Quantitative analysis revealed the amount of VOC emitted
(RG) and that of the labeled compound not adsorbed into the sample (RG’).
The adsorptive capacity of the labeled compound (K’) was calculated by total
amount of the labeled compound (RA’) and the amount of the labeled
compound in gas phase of bag (RG’). It is possible for K’ and K to be of equal
value. Thus, RS and RA can be calculated by estimated value of adsorptive
capacity (K) and the emitted amount of VOC from the sample (RG). And it was
cnsidered that adsorptive capacity varies in inverse proportion to the amount
of gas present and exhibits additivity with respect to sample amount.
We then tried to estimate the amount of VOC emitted from multiple
samples. The K and RA values for sample-A and sample-B were estimated by
the labeled compound addition method as follows: Sample-A: K = 7.70, RA =
2.77 μg/TP, RG = 0.32 μg/Bag, Sample-B: K = 1.24, RA = 0.17 μg/TP, RG =
0.08 μg/Bag. One piece of sample-A and four pieces of sample-B were used
for the estimation. The integrated values of K and RA were calculated as 12.7
and 3.45 μg, respectively. The value of RG predicted using K and RA was 0.25
μg/bag, and that measured by using the bag method was 0.27 μg/bag. Thus, the
predicted and measured values of RG were in good agreement with each other.
This suggests that the method proposed in this study can be successfully
applied for estimating the amount of VOC (RG).
In Chapter 5, the entire study is reviewed and the results of this study and
the matters to be examined in the future are summarized.
