The tar content of product gas is one of the major problems of biomass gasification. In this work, two methods for sampling and analyzing tars were compared: The wet chemical method according to the tar protocol and a solid phase adsorption (SPA) method with Tenax® TA followed by thermal desorption. Both methods are analyzed with gas chromatography (GC) coupled with mass spectrometry (MS). The aim of this paper is to show the feasibility and usefulness...
