These are the supplies you need for your Markes thermal desorber.
- Quantitative sample recollection 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 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 - ultravolatiles, semivolatiles (up to n-C40), plus reactive species - mercaptans, CS gas, and so forth - 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
The analytical technique known as thermal desorption (TD) provides the ability to measure volatile contaminants in air, toys, building materials, car cabins, and food. When the TD systems from Markes International are combined with GC and GC/MS systems, the results meet current requirements with the sensitivity and dynamic range to meet future needs. Markes International TD platforms allow analysis of single tubes, real-time air samples, and canisters with options for automated analysis. Markes has introduced several key technical advances that now set the standard for TD instrumentation.
