Preferred term

TD-GC-MS  

Definition

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