- For over a decade, Markes International has pioneered and commercialised enhancements to analytical TD instrumentation and associated sampling apparatus. The following examples of key technical advances have all been introduced by Markes since 1997 and now set the standard for TD instrumentation:
- SecureTD-Q™ (quantitative re-collection of ALL split flows for repeat analysis), which overcomes the historical one-shot limitation of TD methods and simplifies method/data validation
- 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
