Tenax Sorbent Tube

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

Tenax GR Sorbent Tubes

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.
