Superior Trapping of Volatiles
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 TenaxTM-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.
TM
Purge and Trap sys-
tem in conjunction with the
Short
Path
TM
Thermal
Desorption System, detec-
tion of volatile organics in the
ppb and ppt level is feasible.
Due to its low affinity for
water, Tenax-GR is especial-
ly useful for the purging and
trapping of volatiles from
high moisture content sam-
ples including the analysis of
volatile organic compounds
in water.
