Thermal Desorption Unit Tubes
(Unconditioned and Conditioned & Capped)
Thermal Desorption Unit (TDU) Tubes
• 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.
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.
