Thermodesorption analysis VDA 278 2011-09
Thermal desorption analysis of organic emissions for the characterization of non-metallic automotive materials.
The emissions of non-metallic materials used for molded parts in motor vehicles are determined according to the VDA 278 standard. For this purpose, two semi-quantitative total values are determined that enable an estimate of the emission of volatile organic compounds (VOC value) and the proportion of condensable substances (fog value).
The analysis includes thermal extraction of the samples, gas chromatographic separation of the emissions and their mass spectrometric detection. In contrast to VDA 277, the individual volatile components are identified and semi-quantitatively determined.
We often use thermal desorption GC-MS (VDA 278 or a modified version) to investigate damage to plastic parts. It is a very sensitive measuring method and allows the detection of the smallest contamination.
