Micro Cryo-Trap - Ordering Information

Electronics Contoller Model 971 (CO2 coolant) or 981 (LN2 coolant)

New Programmable Micro Cyro-cooling and heating trap for the Cryo-focusing of volatiles and semivolatiles at the head of GC capillary columns.

Two models of the Micro Cryo-Trap are now available. The Model 971 is designed for liquid CO₂ use only for cryo-trapping temperatures down to -70 °C. The Model 981 is designed for Liquid Nitrogen use only 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 1200 deg/minute. Most users prefer to use the C0₂ version of the GC Cryo-Trap (Model 971) due to the ease of handling liquid C0₂ 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 981) must be used. The liquid nitrogen delivery lines are larger than the CO₂ 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, 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 971 for use with C0₂, or the Model 981 for use with liquid Nitrogen. Although the Cryo-Trap can be used for both CO₂ and LN₂, the electronics are not interchangeable for the two systems.

You must then select which installation kit is required based on the make and model of your gas chromatograph. Either of the two Micro Cryo-Trap(tm) models will fit the same installation kits listed.

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 relays, mounting hardware, cables and other parts required to mount the Cryo-Trap into the particular model of gas chromatograph.
