Abstract

Apparatus for the detection of an analyte in air comprising: (a) an air sampling system for collecting an air sample comprising a mouthpiece (10) and a fan connected (13) to the back of the filter; (b) a first enrichment stage (11) for enrichment of the analyte comprising a thermal adsorption/desorption filter creating a non-laminar gas flow for adsorption of the analyte on the filter surfaces encased in a housing having a gas inlet and outlet connected to valves and a heat source for heating the filter to a temperature high enough to evaporate the analyte but low enough to avoid decomposition of the analyte; (c) means for transport of the desorbed analyte from the filter to a second enrichment stage for the further enrichment of the gaseous analyte comprising a cold trap (32) for condensing the analyte; (d) means for extraction of the condensed material with a solvent; (e) means for collecting the solution enriched in analyte from the cold trap; (f) means for transport of the collected liquid sample to an analytical detection system for the detection of the analyte. Also claimed is the adsorption/desorption filter of the first enrichment stage and a method of detecting an analyte.
