Anasorb Sorbent Tubes

The Anasorb^® name is used for SKC proprietary sorbents of all types.

To select a tube for a specific compound refer to the SKC Sampling Guides or use our SKC online Hazard Database

Anasorb^® 747

Anasorb^® 747 is a synthetic carbon with low ash content which studies showed as a candidate material for sampling polar organic compounds that cannot be sampled using coconut charcoal, such as ketones. Anasorb 747^® has properties similar to the best petroleum charcoals and can be used for a very wide range of polar and non-polar organic vapours. When combined with a solvent appropriate to mixtures such as dimethylformamide, successful sampling is possible for a majority of organic vapours.

Anasorb^® 727

Anasorb^® 727 is a microporous polymer for sampling less volatile reactive and polar compounds. It is derived from cross-linked styrene and similar monomers, and its sorbent properties are similar to Chromosorb^® 106. The surface area is large, very unreactive, and extremely hydrophobic.

Anasorb^® 708

Anasorb^® 708 is equivalent to Chromosorb^® 108.

Anasorb^® C300

Anasorb^® C300 sorbent is equivalent to Hydrar, Carulite.

Anasorb^® CSC

Anasorb^® CSC sorbent has a high surface area for sampling a broad range of primarily non-polar compounds.

Anasorb^® GCB1/GCB2

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.
