Thermal Desorption Tube, Carbosieve S-III/Anasorb GCB1/Anasorb GCB2, Unconditioned, 1/4in OD x 3 1/2in size stainless steel tube, 3 sections, 250/150/100 mg sorbent, 60/80 mesh

SKC offers single and multiple-bed Thermal Desorption Tubes that meet the requirements of EPA Method TO-17 for the determination of sub-ppb VOCs in ambient air. SKC Thermal Desorption Tubes are designed for compatibility with Perkin Elmer or Markes International thermal desorbers.   SKC sorbent technology research has produced superior materials for the collection of organic compounds for thermal desorption. To be suitable for thermal desorption, sorbents must meet exacting specifications that include low contaminant background, high thermal stability, and sufficient adsorptive strength to retain components of interest, yet release them quickly when heat is applied. Thermal desorption techniques offer the advantage of greatly improved analytical sensitivity. Because solvents are not used for desorption, the collected sample is not diluted and, in most cases, analytical recovery is so close to 100% that desorption efficiency corrections are not required.
