The characterisation chain for volatile organic compounds implemented in our analytical chemistry laboratory consists of a thermodesorption or headspace injector coupled to a gas chromatograph and a mass spectrometer or FID.
The approach is both qualitative and quantitative, and identifies volatile compounds.
Emissions analysis coming from complete part are performed using an emission test chamber VCE1000. The compounds emitted by the whole part are collected by sampling the air in the chamber and is analyzed (GC/MS, GC/FID) by liquid (HPLC) or gas chromatography for the VOC, and by the sensory panel SERCOVAM for the smell.
Those analysis are in accordance with requirements of standards as VDA 276, VDA276-1 (VDA276 et VDA 276-1), ISO 16000-9 (ISO 16000 9), …
Automotive manufacturers have developed test methods to assess emissions from parts of the vehicle interior (seats, carpets, dashboard, door panel, headliner ...) Renault VOCs D493027 (D49 3027), Odor D493046 (D49 3046) and aldehydes and ketones D493085 (D49 3085), (1027 2769 or VCS 1027,2769), Volkswagen PV 3942 (PV3942), BMW GS97014-3. For the others markets, the determination of the Emission of Volatile Organic Compounds are performed according to ISO 16000-3 or ISO 16000-6.
