Depending on the make and model of your GC, an installation
kit must be ordered separately as described below. First you must
decide which model of Cryo-Trap is required for your application;
the Model 951 for use with C0
2
, or the Model 961 for use with
liquid Nitrogen. Neither the GC Cryo-Trap or its related electronics
are interchangeable between the two cooling gases. You must
then select which installation kit is required based on the make
and model of your gas chromatograph. Either of the two Cryo-Trap
models use the same installation kit listed below.
Custom I.D. Manufactured Cryo-Traps
O
ur standard GC Cryo-Trap can handle up to megabore
capillary columns (1.0mm O.D.). In response to
specific customer requests for larger trapping
capabilities, we have designed and produced Cryo-Traps that can
handle either 1/16" O.D. tubes or 1/8" O.D. tubes. To
accommodate these size tubes, the inside capillary tube in the
cryo-trap is manufactured with either 1/16" I.D. or 1/8" I.D.
stainless steel capillary tube. These traps can be used either
inside or outside the GC oven depending on the users
requirements. These larger I.D. traps have been used by several
users for high flow applications and trapping of analytes outside
the GC oven. Call SIS with your specific requirements or for
custom mounts or other modifications.

GC Cryo-Trap
T
wo models of the GC Cryo-Trap are now available. The
Model 951 is designed for liquid CO
2
for cryo-trapping
temperatures down to -70°C. The Model 981 is designed
for Liquid Nitrogen for cryo-trapping temperatures down to -180°C.
Each model can maintain any cooling temperature within ±3°C from
its minimum temperature up to room temperature. In order to release
the trapped volatiles from the GC Cryo-Traps, both models can heat
the GC Cryo-Trap at temperatures up to 400°C at a heating ramp rate
in excess of 800°/minute. Most users prefer to use the CO
2
version of
the GC Cryo-Trap (Model 951) due to the ease of handling liquid CO
2
and for applications where -70°C is an acceptable lower temperature
limit.
If lower temperatures are required, then the liquid nitrogen
version of the GC Cryo-Trap (Model 961) must be used. The liquid
nitrogen delivery lines are larger than the CO
2
lines and the liquid
nitrogen lines should be insulated. This makes installation somewhat
more cumbersome. In addition the Liquid Nitrogen version uses more
cooling gas and is slightly more audible.
Model 951 GC Cryo-Trap for use with Liquid C02
The Model 951 GC Cryo-Trap is designed for use with liquid CO2 tanks
with a DIP tube. The minimum temperature of cooling is -70°C. This model
comes with the GC Cryo-Trap, the dual temperature cables and stainless
steel connecting line.

Model 961 GC Cryo-Trap for use with Liquid Nitrogen
The Model 961 GC Cryo-Trap is designed for use with liquid nitrogen
tanks (low pressure). The minimum temperature of cooling is -180°C. This
model comes with the GC Cryo-Trap, the dual temperature cables and cop-
per connecting line.

Cryo-Trap Installation Packages
Depending on the make and model of Gas Chromatograph one of the
installation packages must be ordered for the installation of the GC 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.
