Tenax Sorbent Tubes
Tenax® TA is a traditional sorbent (porous polymer) for trapping medium to high boiling compounds; it is especially useful for low concentrations because of its low background. Tenax TA is hydrophobic and is suitable for use in EPA Method TO-17 or IP-1B and other thermal desorption applications.
Tenax® GR is a Tenax/graphite composite which extends the range of Tenax to lower boiling compounds. It retains the ability of Tenax to be cleaned easily to a very low background and is widely used in thermal desorption applications.
To select a tube for a specific compound refer to the SKC Sampling Guides or use our SKC online Hazard Database
Note that thermally purged sorbent tubes are for immediate use in the field. Unpurged tubes are purged by a laboratory as needed.

Anasorb® GCB1 - Graphitised Carbon Black for sampling aliphatic and aromatic hydrocarbons and is equivalent to Carbotrap® B (20/40) and Carbopack B (60/80). This sorbent has proven to be valuable for sampling compounds of intermediate to high volatility.
Anasorb® GCB2 - Graphitised Carbon Black for sampling less volatile compounds. This sorbent has a low surface area and is equivalent to Carbotrap® C (20/40) and Carbopack C (60/80), and is useful in collecting semi-volatile organic compounds (SVOCs).
Note that thermally purged sorbent tubes are for immediate use in the field. Unpurged tubes are purged by a laboratory as needed.
