Thermal Desorption
Thermal desorption (TD) provides unique analyses in applications for forensics, defense, and general emissions testing.
When the TD systems from Markes International are combined with Agilent GC and GC/MS systems the results meet current requirements with sensitivity and dynamic range to meet current regulations and future needs.

Product Details
Features
- Quantitative sample re-collection of all the 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 tube tags 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 - 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
- Specialist sorbent tubes: Certified reference standards, SafeLok™ tubes, Silcosteel tubes
- A range of unique sampling tools for measuring volatile and semi-volatile organics in challenging matrices: liquids/solids/emulsions, breath, in-situ soil, polymers, natural products, construction products, etc
