Thermal Desorption Systems (TD)

Thermal desorption (TD) arose out of the need to improve upon conventional sample preparation techniques such as solvent extraction, solid-phase microextraction, purge-and-trap and static headspace. It gives greater sensitivity than these techniques and can be used for a wider range of compound classes ranging in volatility from C2 to n-C44 hydrocarbons. TD is also applicable to a wide range of sample types – solids (using dynamic headspace, headspace sorptive extraction or direct desorption), liquids (using immersive sorptive extraction) and gases (using pumped sampling, passive sampling, on-line sampling or canisters). It is safer and more environmentally friendly than solvent extraction, is easily automated, easy to validate and complies with key standard methods.
