T
he Cryo-Trap consists of a small heating/cooling cham-
ber. In the center of the chamber is a small stainless
steel capillary through which the capillary column freely
passes. Capillary columns up to megabore (0.53mm I.D.) diame-
ters can be used. Around the stainless steel capillary tube a heat-
ing coil is wound to provide for the rapid heating of the capillary
tube. A thermocouple provides accurate measurement of both the
cooling and heating temperatures. Either Liquid CO2 or Liquid
Nitrogen for cooling is introduced into the Cryo-Trap, and is
exhausted through the outlet which can either be vented into the
GC or a tube can be attached to vent external to the GC oven.
The control of the Cryo-Trap is provided via output signals of
the SPTD Model TD-5. Both the Cryo-Cooling and heating
temperatures are set SIS software.
For other systems see the Cryo-Trap Systems listed in the
GC section of this catalog.
Application Notes on the Cryo-Trap
Application - See pages in the GC section of this catalog for
the GC Cryo-Trap for use with the Headspace Sampler and other
Thermal Desorption Systems.
A large number of application notes on the Cryo-Trap and its
use with Headspace and Thermal Desorption Systems are avail-
able from S.I.S. at no charge. Call or write for your FREE copies
of these application notes.

minute.
Cryo-Trap Installation Packages for TD-5
Depending on the make and model of Gas Chromatograph one
of the installation packages must be ordered for the installation of
the Cryo-Trap.The Cryo-Trap installation kits include the relays,
mounting hardware, cables and other parts required to mount the
Cryo-Trap into the particular model of gas chromatograph. The
install kit is required for all GC's except the Agilent 6890.
See page C38 - C39 for additional details.
