High-quality thermal desorption tubes by Markes International. These sorbent tubes are suitable for ppt to ppm concentrations of volatile organic compounds (VOCs) in ambient, indoor, and industrial hygiene environments. Available in both stainless steel and glass (for thermally labile VOCs), they fit Markes ULTRA-UNITY™, PerkinElmer, and Shimadzu thermal desorbers. Packed tubes come with a report detailing the total mass of sorbent in the tube; conditioned tubes also include a blank chromatogram.

Variety of sorbents to collect a wide range of VOCs, including Tenax® and carbon sorbents.
Use glass tubes for maximum inertness in active sampling.
Choose stainless steel tubes for either active or passive sampling. No sampling pump necessary for passive sampling with diffusion caps!
Individually etched with unique serial number for convenient sample identification.
Available unconditioned or preconditioned and ready to sample. Tubes are reusable after thermal desorption.
