These analyses fit in with the framework of validations on car parts (cab) for manufacturers like Volkswagen and PSA to answer to ever more severe legislative requirements.
They are conducted by Gas Chromatography (GC). In principle, the sample is placed in a sealed vial then gently heated in order to partially vaporise the volatile organic compounds it contains. A fraction of these vapours is then separated by Gas Chromatography and quantified using an FID detector or by Mass Spectrometry (MS).
Calibration of the device is performed using standard acetone solutions in butanol. The content of Total Organic Composites (TVOC) is calculated in relation to the mass of the sample and the surface of peaks appearing on the chromatogram.
