his new handy wall chart can help guide you through the
determination of the adsorption and desorption properties
of Tenax TA for use with your thermal desorption
applications. This chart is the result of more than 6 months of work
in which more than 200 organic compounds were analyzed at 20
degree temperature intervals from 0°C to 300°C. The breakthrough
volume for each organic was analyzed in triplicate for breakthrough
volumes from 0.001 liter (1.0 ml) through 1.0 liter at the various
temperatures. Breakthrough Volumes greater than 1.0 liter per
gram were determined through linear regression analysis of the
breakthrough volume data from at least 7 different temperatures.
The complete description of the method utilized to determine the
breakthrough volumes is described in “The Mass Spec Source”,
Vol. XVIII, No. 4, July 1994. The breakthrough volumes for 198
organic compounds are listed on the chart at temperatures from
0°C to 300°C at 20 degree intervals. The Breakthrough Volumes
are listed in Liters of air per gram of Tenax TA resin. The chart is
color coded with Breakthrough Volumes less than 0.010 Liters (10
milliliters) indicated in red and Breakthrough Volumes greater than
10 liters indicated in blue. This makes it easy to determine the gas
volatiles which can be purged through the Tenax TA resin at a
particular temperature as well as the temperature required to elute
or desorb a particular range of organics off the Tenax TA resin. the
charts are printed on 24" x 36" heavy paper stock and are also
available laminated in plastic for extra durability and long life. The
following classes of organic compounds were analyzed:
