Innovations in routine sample analysis for volatile content using purge and trap technique: conserving helium and improving laboratory throughput Gas chromatography for VOC analysis As stated previously the most common technique used to detect, identify and quantitate VOC is gas chromatography with flame ionization (FID) , electron capture (ECD ) or mass spectrometry (GC-MS) detection.
VOC vials and bottles used to store samples should be prepared prior to transferring the sample to thecontainer. That is, methanol (or other chemical preservative) and surrogate compounds should bepresent in the container, and the tared weight recorded prior to introduction of the sample.
