    Specifications

    MARKES Thermal Desorption

    Thermal desorption (TD) provides unique analyses in applications for forensics, defense, and general emissions testing.

    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
