Adsorbent tube evaluation for the preconcentration of volatile organic compounds in air for analysis by gas chromatography–mass spectrometry

Carol A. McCaffrey,   John MacLachlan  and  Beverley I. Brookes  

Abstract

Gas chromatography–mass spectrometry is a powerful analytical technique for analysing a wide range of volatile organic compounds (VOCs). For trace amounts of VOCs a preconcentration stage is normally required. Adsorption of the components onto a solid sorbent and recovery by thermal desorption is a widely used preconcentration method. A comparison between different adsorbent materials has been carried out by generating a standard atmosphere. The problems encountered during the analysis owing to water adsorption are discussed.
