Detection of volatile organic compounds from wood-based panels by gas chromatography-field asymmetric ion mobility spectrometry (GC-FAIMS)

摘要

The focus of this work was to detect formaldehyde (HCHO) as a very volatile compound (VVOC) among other volatile organic compounds in the low concentration ranges that are relevant for the production control in wood processing industries. We show that a quick and easy derivatization of HCHO can be used for a reliable and straightforward identification with GC-FAIMS. Headspace samples of specimens made from wood-based panels were collected and pre-concentrated on a conventional solid phase microextraction fiber (SPME) and thermally desorbed in a split/splitless GC-injector. A standard gas-mixer generator based on the dynamical permeation principle was used to produce known concentrations of HCHO. The results are compared with gas chromatography—mass spectrometry (GC-MS).
