Air Adsorption Tubes and Sorbents

Thermal Desorption Sampling Tubes AERO TD Tubes

AERO TD Packed Tubes

AERO TD Packed Tubes are adsorbent tubes packed with sorbent(s) and thermally conditioned for CP4010/4020 and MSTD. Please select 3 mm I.D. or 4 mm I.D. tubes depending on the sorbent mass. Ordering malt-bed type sampling tubes, please select sorbent name and mass. Adsorbent tubes of Spelco is available thermally conditioned type only.

Representative Sorbents

Tenax TA

Tenax TA is a heat resistant resin with 2,6-diphenyl-p-phenylene oxide structure. It is suitable for sampling of volatile and semi-volatile compounds, and it is not susceptible in air because of its low affinity to water and alcohol. It cannot capture highly volatile compounds, so generally I is used combined with carbon type adsorption. Take care that repeatedly usage around the maximum operation temperature makes the effect to blank.

Tenax GR

Tenax GR is made by adding 23 % graphite carbon at the polymerization of Tenax. It has higher breakthrough volume than conventional, due to the addition.

Carbotrap (Supelco)

Carbotrap is graphite carbon black with 100 m2/g surface area and suited to adsorption for C5-C8 compounds in air. Produced under high temperature, this has high thermal stability and less bleeding by thermal desorption. Because of its large pore size (20/40 mesh), the residence of sampling is low and the back pressure does not increase

Carboxen 1000 (Supelco)

Carboxen 1000, a carbon molecular sieve type adsorbent, have high hydrophobicity and enables accurate sampling even under high temperature. This adsorbent have large surface area and its pore size is optimized to highly volatile compounds like vinyl chloride, so this adsorb smaller size molecular compounds well.

Carbopack B (Supelco)

Carbopack B is a graphite carbon black material as same as Carbotrap, but its mesh size is smaller : 60/80 mesh and is used as loaded in narrower sampling tubes. The adsorption flow is relatively slow, the recommendation is under 20 mL/min. This is a spherical carbon molecular sieve type adsorption, its surface area is big, approximately 820 m2/g, the pore size is 15 Å - 40 Å. This is suited for adsorption of low molecular weight compounds like chloromethane in air.
