- Adsorbent Resins Guide (This Page)
Adsorbent Resins are utilized by Purge and Trap (P&T) and other thermal desorption applications. A wide variety of adsorbent resins are available from many suppliers and manufacturers. In order to properly select an adsorbent resin for a particular application the user must have knowledge of the types of analytes that he wishes to analyze as well as an understanding of the physical properties of the adsorbent resins available. This is the accumulation of about 2 years work by Scientific Instrument Services to collect and compile this data.
The data herein is designed for use by the scientific community to aid in the use of adsorbent resins. As such you are free to take and use this data for you experimentation. However the tables, charts and data enclosed herein cannot be reproduced in publications or other information sources including the Internet without the written consent of SIS. SIS will grant the right to republish this data as long as it is in the best interests of SIS and that SIS receives prominent recognition as the source of this information.
| Tenax® TA | is a porous polymer based on 2,6-diphenylene oxide. It has been specifically designed for the trapping of volatiles and semi-volatiles from liquid or solid matrices. Both the EPA and NIOSH specify the use of Tenax in their standard methods. Tenax TA is a low bleeding material with a low level of impurities. Due to its low affinity for water, Tenax TA is especially useful for the purging of volatile organics from high moisture content samples including the analysis of volatiles organics in water. |
|---|---|
| Tenax® GR | is a composite material of Tenax TA and 30% graphite. The resulting material gives a higher breakthrough volume for most volatile organics, yet still has a low affinity for water. In addition Tenax GR maintains its high temperature stability to 350 degrees C. These properties make Tenax GR an ideal adsorbent for the trapping of volatiles from air, water and solid matrices. Due to its low affinity for water, Tenax GR is especially useful for the purging of volatile organics from high moisture content samples including the analysis of volatiles organics in water. |
| Carbotrap | graphitized carbon blacks are ideal adsorbents for trapping a wide range of airborne organic compounds from butane/pentane hydrocarbons through the PCB's. It is usable to 400 degrees C and due to its coarse mesh size will provide minimal backpressure in the desorption tubes. Manufactured by Supelco. |
| Carbotrap C | graphitized carbon blacks is an ideal resin for the trapping of a wide range of organic volatiles. It also has a coarse mesh size and can be used to 400 degrees C. Manufactured by Supelco. |
| Carboxen 569 | is a carbon molecular sieve which is ideal for the trapping of the smaller organic analytes. It has a low affinity for water and can be used to trap many C2-C5 volatile organics. It is often used in conjunction with Tenax TA to produce mixed bed resins. Manufactured by Supelco. |
| Carbosieve SIII | is a carbon molecular sieve that has the greatest ability for the trapping of the low molecular weight organics due to its large surface area. |
| Glass Beads | are most useful for the trapping of large molecular weight compounds. It will not retain any of the light volatiles, aromatics or other medium boilers. Therefore it is most frequently used in mixed bed applications with other adsorbent resins. Available from Supelco. |
