摘要：

A novel small enrichment unit based on the trap and thermal desorption technique was used in combination with a portable electronic nose. A better detection limit. is achieved due to the trapping procedure during sampling. A better selectivity is achieved by means of degradation of disturbing compounds from the analysis. Especially, the extraction of ethanol is important for the analysis of alcoholic beverages. Influences to water changes are minimized. Selected examples with use of this enrichment unit show the possibilities for enhanced measurement with known and new applications. (C) 2000 Elsevier Science S.A. All rights reserved.
