We offer the highest quality thermal desorber (TD) kits and supplies including TD tubes and conditioning ovens.
Thermal Desorber Tubes
For your convenience, our TD tubes are offered in both stainless steel and glass. Each tube maintains its unique serial number which is etched for easy identification. Tubes are offered with a variety of sorbent packing materials for many GC applications including indoor and outdoor air monitoring, analysis of flavors and fragrances, and the analysis of outgassing from packaging, polymers, pharmaceuticals, and semiconductor material. These tubes are available conditioned and unconditioned and ship with end caps for short-term storage.
Condition tubes faster and easier with our ATD tube conditioning oven. Condition any number or combination of stainless steel and glass tubes simultaneously without wasting gas.
The Carbotrap 349 is conditional at 350 °C. The recommended temperature is a maximum temperature of 400 °C for this sample tube with a desorption temperature of 330 °C. The tubes approximate analyte volatility range is n-C3 to n-C16 and the typical analytes for the Carbotrap 349 are NIOSH Method 2549.
The Tenax® TA is conditioned at 320 °C. PerkinElmer recommends a maximum temperature of 350 °C for this sample tube with a desorption temperature of 300 °C. The tubes approximate analyte volatility range is n-C7 to n-C26 and the typical analytes for the Tenax® TA are aromatics except benzene, apolar compounds (BP>100 °C) and less volatile compounds.
This tube is a multifunctional combination tube which allows detection of 3 compounds. The SS tubes are compatible with pumped and diffusive air monitoring. Suitable for direct sampling of solids and liquids. PerkinElmer tubes are manufactured to the tightest spcifications to ensure trouble free operation and high quality analysis results.
The Carbopack™ B is conditioned at 350 °C. PerkinElmer recommends a maximum temperature of 400 °C for this sample tube with a desorption temperature of 330 °C. The tubes approximate analyte volatility range is n-C5 to n-C12 and the typical analytes for the Carbopack™ B are a wide range of VOCs.
