The identification of organic compounds in wood using thermal desorption GC-MS - possibilities and limitations
P Jüngel, E Melcher
There is a clear need for the analytical characterisation and identification of organic compounds and their derivatives in different phases especially in timber. In this context the paper describes a rapid and powerful gas chromatographic method for the determination of insecticides, biocides and "other" organic substances in treated and/or modified wood. The main advantage of this procedure is that wooden material can be analysed directly without any further sample preparation. In principle the technical equipment using a mass selective detector is suitable for identifying as well as quantifying thermal desorbable compounds in only one analytical run. The main emphasis of this contribution, however, is to show the possibilities and limitations of this technique.
