T
enax-TA is a porous polymer resin based on 2.6-
diphenylene oxide. It has been specifically designed for
the trapping of volatiles and semi-volatiles from air or
which have been purged from liquid or solid sample 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 and has replaced Tenax-GC, which was distributed in
the past. Tenax-TA can be applied both as a column packing mate-
rial and for traps for organic volatile and semi-volatile compounds.
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-TA is especially
useful for the purging and trapping of volatiles from high moisture
content samples including the analysis of volatile organic com-
pounds in water.

-TA & Tenax-GR
Tenax is a porous polymer resin based on 2,6-diphenylene
oxide. It is widely used for trapping VOC's from air and liquids
for subsequent analysis. Tenax is especially beneficial in trap-
ping volatile organics from high moisture content samples, and
used in conjunction with the Short Path Thermal Desorption
System. Low level detection of VOC's in the ppb and ppt is pos-
sible.
Tenax-TA replaced the previous polymer Tenax-GC which
has been discontinued. Tenax-TA which is a specially
processed Tenax is designed primarily as a trapping agent, and
has very low levels of impurities. Tenax-GR is a composite of
Tenax-TA with 30% graphite as an integral part of the mixture.
The added graphite increases the breakthrough volume for
many organic volatiles while still maintaining the low affinity for
water.
Applications include the following:
•
Purge and Trap of Volatiles from Water
•
Trapping of Volatiles from Environmental Air
•
Trapping of Volatiles from Human Breath
•
Trapping of Flavors and Fragrances from
Plants and Commercial Products
•
Trapping of Volatiles from Soils
•
Personal Exposure Monitoring
Before use it is recommended that Tenax-TA/Tenax-GR be
thermally conditioned with a high purity gas at elevated tem-
peratures to remove any residual components using the follow-
ing procedure. It is important that no oxygen be permitted to
enter the Tenax-TA/Tenax-GR material when it is at elevated
temperatures.
Conditioning of Tenax-TA & Tenax-GR
Traps for Thermal Desorption
1. The Tenax-TA/Tenax-GR should be packed in the sam-
ple tube between two silanized glass wool or quartz wool plugs.
2. High purity helium or nitrogen (less than 1 ppm oxygen)
should be passed through the sample tube with Tenax-
TA/Tenax-GR at a flow of 10 to 50 ml/min.
3. Begin to heat the sample tube with Tenax-TA/Tenax-GR
from room temperature up to 300 - 340° C at a temperature
ramp of 4 to 10° per minute.
4. When the maximum temperature is reached, maintain
the sample tube at this temperature for 2 to 4 hours with con-
stant gas flow thru the Tenax-TA/Tenax-GR.
5. Cool the sample tube with continued gas flow. As soon
as it is cool, seal the tubes until ready for use. Do not use plas-
tic or rubber seals. PTFE seals in the caps can be used for stor-
age.

T
he new Tenax-GR is a composite material of Tenax and
30% graphite. The resulting material gives higher break-
through volumes for most volatile organics, yet still has a
low affinity for water. In addition Tenax™-GR maintains its high
temperature stability to 350° 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.
™

tem in conjunction with the

Due to its low affinity for

ly useful for the purging and

ples including the analysis of
