Tenax® GR Breakthrough Volume Data |
The new 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 samples. Using thermal desorption techniques such as the S.I.S. Purge and Trap system in conjunction with the Short Path Thermal Desorption System, detection of volatile organics in the ppb and ppt level is feasible. Due to its low affinity for water, Tenax GR is especially useful for the purging of volatiles from high moisture content samples including the analysis of volatile organic compounds in water. Since its density is twice that of Tenax TA, this enables a larger amount of the Tenax GR resin to be placed inside the desorption tube, thereby increasing the ability to retain volatiles on a small resin bed.
Before use it is recommended that Tenax GR be thermally conditioned
with a high purity gas at elevated temperatures to remove any
residual components using the following procedure. It is important
that no oxygen be permitted to enter the Tenax TA material when
it is at elevated temperatures. See Conditioning Instructions.
