Significance of Topic
Understanding and controlling volatile organic compound (VOC) and semi-volatile organic compound (SVOC) emissions from automotive interiors is critical for passenger health, regulatory compliance and perceived vehicle quality. Thermal desorption coupled with gas chromatography–mass spectrometry (TD-GC/MS) enables sensitive, high-throughput profiling of interior material emissions, supporting both product development and quality assurance.
Objectives and Study Overview
This work demonstrates a complete TD-GC/MS workflow to identify, quantify and characterize VOC and fogging substances emitted by non-metallic automotive materials. Key aims include:
- Compliance with major automotive industry standards (VDA, ISO 12219 series, JAMA, OEHHA-based limits).
- Establishment of a rapid micro-chamber screening protocol for both surface and bulk emissions.
- Evaluation of instrument performance for full-scan and selected-ion monitoring (SIM) acquisition modes.
Methodology and Instrumentation
Sample preparation and analysis follow defined micro-chamber and direct desorption procedures:
- Micro-chamber testing (ISO 12219-3): samples equilibrated at 65 °C for 20 min, air flow rates of 50 ml/min for VOC and 250 ml/min for formaldehyde, sampling on sorbent tubes for 15 min.
- Direct thermal desorption: 30 min at 90 °C for VOC value, 60 min at 120 °C for fogging value with two split ratios (high and low) and 2-stage graphitized carbon trap (–30 °C to 300 °C).
- GC parameters: Trace GC, RTX-5 ms capillary column (30 m × 0.25 mm × 0.25 µm), oven ramp from 40 °C to 280 °C in multi-segment program, constant He flow of 1.5 ml/min.
- MS detection: Thermo Fisher ISQ single quadrupole, electron ionization scan m/z 29–370 at ~200 ms/scan, optional SIM for high sensitivity on target ions.
- Autosampler and sorbent tubes: Markes TD-100 with electrically cooled focusing trap, cryogen-free cooling, capacity for up to 100 tubes and optional canister sampling modules.
- Calibration and QC: liquid standard mixtures of normal alkanes (C7–C16) and aromatic VOCs injected via standard loading rig; quantitative routines based on VDA 278 toluene and hexadecane equivalents.
Main Results and Discussion
Instrument performance and emission testing yielded the following highlights:
- Efficient capture and desorption of compounds from C2 to n-C40, including reactive VOC such as H2S and N2O.
- High scan speeds (up to 70 amu/s) with excellent repeatability and sensitivity, S/N ratios exceeding 5 × 10^4 in full-scan and SIM modes.
- Correlation of micro-chamber results with longer-term bag and small chamber studies, validating rapid screening against established methods.
- Leather sample emissions: total VOC value of 81.3 µg/g and fogging contributions assessed using hexadecane equivalents, identifying 17 major peaks between 9.35 and 19.84 min.
Benefits and Practical Use
The combined Markes TD-100 and Thermo Fisher ISQ GC/MS platform offers:
- Versatility across low to high concentrations and a wide compound range without cryogens.
- High throughput with automated leak test, purge-to-vent, backflush trap and split flow control.
- Fully software-controlled workflows enabling repeat injections, precise tube tagging and robust automation.
- Compliance with automotive regulatory and voluntary programs, including VDA 270–278, JAMA and ISO 12219 series.
Future Trends and Opportunities
Advances likely to shape interior emission analysis include:
- Integration of ultra-fast GC columns and high-resolution MS for enhanced speciation.
- Real-time cabin air monitoring using online TD modules and direct sampling interfaces.
- Expanded data analytics and machine learning to predict long-term emission profiles from rapid screening data.
- Harmonization of global regulatory limits and adoption of portable TD-GC/MS units for end-of-line quality control.
Conclusion
Thermal desorption GC/MS using a cryogen-free focusing trap and single-quadrupole MS provides a robust, flexible and compliant solution for automotive interior emission testing. The workflow described meets major industry standards, delivers high sensitivity across a broad volatility range and supports rapid screening and detailed compound identification in a single platform.

Analysis Goal
• The analysis procedure serves to indentify the emissions from
non-metallic materials that are used in Automobiles. For example:
• Textile
• Carpets
• Adhesives
• Sealants
• Foams
• Leather
• Plastics
• Transparancies
• Paint
• Combination Materials
31
Description of the method- VOC
• The samples are thermally extracted and the emissions analyzed using
GC/MS
• There are two half-quantitative summation values determined that
determine the emission levels for
• volatile organic compounds (VOC-Value) and
• The portion of condensable substances (Fogging-Value)
• The VOC value according to VDA 278 is the sum of high to medium
volatile substances and is reported as toluene equivalent results.
Substances with vapor point or retention times for substances up to
Eicosan (C20) are determined and reported.
• The sample is analyzed for 30 minutes at 90°C
32
Description of the method determination- Fogging
• The Fog value is the sum of the heavy
volatile substances that occur after the
elution time for n-Hexadecane. This will
be reported as the Hexadecane
equivalents.
• These are the substances in vapor
pressure range from n-
Alcanes „C16“ up
to „C32“ are reported
• These substances can condensate at
slightly warmer than room temperatures
and can be seen as “Fog Film” on the
inside portion of windshields
