Solvent vapour monitoring in work space by solid

摘要

Solid phase micro extraction (SPME) is a fast, solvent-less alternative to conventional charcoal tube sampling/carbon disulfide extraction for volatile organic compounds (VOC). In this work SPME was compared to the active sampling technique in a typical lab atmosphere. Two different Types of fibre coatings were evaluated for solvent vapour at ambient concentration. A general Purpose 100 μm film polydimethylsiloxane (PDMS) fibre was found to be unsuitable for VOC Work, despite the thick coating.
