Micro Cryo-Trap

T

wo models of the Micro Cryo-Trap are now available.

The Model 971 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 Micro Cryo-Traps™, both models can heat the Micro Cryo-

Trap™ at temperatures up to 400°C at a heating ramp rate in

excess of 400°C/minute. Most users prefer to use the CO

2

version of the Micro Cryo-Trap (Model 971) 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 Micro Cryo-Trap (Model 981) must be used. The

liquid nitrogen delivery lines are larger than the CO

2

lines and the

liquid nitrogen lines must be insulated. This makes installation

somewhat more cumbersome. In addition the Liquid Nitrogen

version uses more cooling gas and is slightly more audible.

Depending on the make and model of your GC, a Micro Cryo

Trap can be ordered as described below.

First you must decide

which model of Micro Cryo-Trap is required for your application;

the Model 971 for use with CO

2

, or the Model 981 for use with

liquid Nitrogen. Although the Cryo-Trap can be used for both CO

2

and LN

2

, the electronics are not interchangeable for the two

systems.

You must then select which installation kit is required based

on the make & model of your gas chromatograph. Either of the

two Micro Cryo-Trap models will fit the same installation kits

listed below.

Model 971 Micro Cryo-Trap

for use with Liquid CO

2

The Model 971 Micro Cryo-Trap™ is designed for use with liquid

CO

2

tanks with a DIP tube. The minimum cooling temperature is

-70°C. This model comes with the Micro Cryo-Trap™, the dual

temperature electronics controller, connecting cables and stainless steel

connecting line.

Model 981 Micro Cryo-Trap for use with Liquid Nitrogen

The Model 981 Micro Cryo-Trap™ is designed for use with liquid nitrogen

tanks (low pressure). The minimum cooling temperature is

-180°C. This model comes with the Micro Cryo-Trap™, the dual

temperature electronics controller, connecting cables and a copper con-

necting 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.
