Thermal desorption (TD) has long had a place as a high-sensitivity alternative to solvent extraction for the determination of volatile organic compounds (VOCs) in environmental health & safety applications. Recent developments have extended its application to routine quality assurance and quality control testing. Whatever the nature of the product or raw material containing the VOCs – solid, liquid, gas, emulsion, resin, etc. – thermal desorption can provide an efficient, readily-validated and cost-effective alternative to conventional laboratory sample preparation methods.

This application note highlights the versatility of thermal desorption for analysing VOCs in materials and process gas streams.

Emissions (or headspace) profiling, direct desorption and on-line sampling of industrial air/gas are covered, each with examples.
