Strengths / Weaknesses

Glass Beads 60:80

Semi-volatiles, solids at room temperature



Thermally stable, inert, low surface area. Acts as a filter at tube inlet, segregating higher boiling compounds from more tenacious adsorbents.Suitable only for large molecules.

Silica Gel 60:80 80:100

Low-boiling polar compounds, esp. chlorinated and sulfur groups



Within optimum range, good adsorption / desorption qualities. Especially useful for separating chlorinated or sulfur compounds from matrices with hydrocarbon interferences.Retains water.

Porous Polymers

Tenax-TA™ 20:35  60:80

C6 to C30s, C2 to Cdepending on functional group



Within optimum range, will readily release what it adsorbs. Does not react with materials. Low affinity for water.May form some artifacts when heated, typically CO2 , benzene, and toluene.

Tenax- GR™20:35 60:80

Volatile organic compounds



An alternative to other carbon based adsorbents for low boiling compounds. Lower affinity for water than Tenax-TA.Lower breakthrough volumes, typically, than carbon molecular sieves

HayeSep D™ 60:80

Low molecular weight compounds, esp. halogen and sulfur groups



Good backup for Tenax where carbon based adsorbents are unsuitable. Retains many low boiling compounds that breakthrough Tenax, esp. in saturated atmospheres.Moderate artifact level at upper temperature limit. High pressure drop.

Chromosorb 106™ 60:80

Low molecular weight, volatile compounds.



An alternative to other polymeric and carbon based adsorbents for low boiling compounds.Low temperature limit, high artifact level. Batch to batch variations.

Carbonaceous Materials


C5 to C12



High thermal stability. Low back-pressure. Hydrophobic.Lower desorption efficiency than Tenax for higher molecular weight compounds when used for sampling in saturated atmospheres, i.e. during thermal stripping.

Carbotrap CJ20:40

Heavy organics: PCBs, PNAs, other large molecules



Same as Carbotrap

Coconut Charcoal 60:80

C2 to C5 volatile organic compounds



High capacity / breakthrough volume for low boiling compounds. Greater retention capability than Carbosieve SIII.Lower desorption efficiency than Carbosieve SIII. Tendency to retain water

Carbon Molecular Sieves

Ambersorb XE-340J (Carboxen-563J)20:45

C3 to C5 volatile organic compounds



High capacity / breakthrough volume for low boiling compounds. Low back-pressure. Hydrophobic.Low desorption efficiency for  polar compounds. May produce sulfur compounds as artifacts, typically SO2.

Carbosieve SIIIJ60:80

C2 to C6 volatile organic compounds



High capacity / breakthrough volume for low boiling compounds. Less water retentive than charcoal. Better desorption efficiency than charcoal for low-boiling hydrocarbons.Low desorption efficiency for polar compounds. Less retentive capability than charcoal.

Carboxen 1000J60:80

C2 to C6 volatile organic compounds



Better desorption efficiency than Carbosieve SIII.Not as retentive as SIII. May produce sulfur compounds as artifacts, typically SO2.
