Thermal Desorption
Thermal desorption (TD) is used to analyze volatile and semi-volatile organic compounds (VOC and SVOC) in environmental, food, forensics, defense, consumer, and other application areas. It combines sample preparation, extraction, and injection into a single automated process.
TD systems from Markes International, combined with Agilent GC and GC/MS systems, offer the sensitivity and dynamic range you need to to meet current regulations and future needs.

Product Details
Features
- Quantitative sample re-collection of all split flows enables repeat analysis of critical samples, easy method validation, and overcomes the one-shot limitation of conventional TD systems
- Electronic tube tagging (TubeTAG™): RFID tags are available for industry standard sorbent tubes
- Diffusion locking (DiffLok™) for enhanced sample integrity and robust (mechanically simple) automation
- Patented inert valving for compatibility with every TD application on a single analytical platform - ultra-volatiles, semi-volatiles (up to n-C40) plus reactive species such as mercaptans, CS gas, etc. - all on one TD system
- Automated internal standard introduction onto blank as well as sampled tubes
- Electronic pneumatics control (EPC) of carrier gas through the thermal desorber ensures consistent compound retention time independent of split flow
- Electrically-cooled sorbent trapping with uniquely fast trap heating rates for splitless capillary GC operation and optimum sensitivity without risk of ice formation
- Off-line conditioning for multiple tubes without the need to blank-off unused tube connections
- Specialized sorbent tubes: Certified reference standards, SafeLok™ tubes, Silcosteel tubes
- A range of unique sampling tools for measuring VOC and SVOC in challenging matrices: liquids/solids/emulsions, breath, in-situ soil, polymers, natural products, construction products, etc.
