摘要：

A sampling unit for a combustion reaction apparatus is described. With this unit it is possible to collect the entire product gases from the combustion experiment in fractions of different volatilities. The sampling unit consists of two Tenax cartridges and a molecular sieve cartridge connected in series. The ethanol eluate of Tenax is analysed qualitatively and quantitatively with GC/MSD and GC/IRD. This solution is also used for microbiological toxicity testing after appropriate dilution. The fraction of highest volatility is desorbed from the molecular sieve and analysed directly via headspace-GC/MSD. The efficiency of this sampling procedure is demonstrated with a styrene polymer and a sample of beech wood.
