Adds Cryo-Cooling Capabilities to your GC.
Programmable cryo-cooling and heating trap for the cryo-focusing of volatiles and semi-volatiles at
the head of GC capillary columns.
The GC Cryo-Trap is used to cryo-focus volatiles at the front of the GC column in a narrow band for subsequent heating and release. We offer multiple sizes, with both CO2 cooling gas or (for lower molecular weight volatiles) liquid nitrogen.
SIS 4-Inch GC Cryo-Trap
(Model 951/961)4-in long cryo-trap for cryo-cooling and heating (cryo-focusing) of volatiles and semivolatiles at the head of GC capillary columns.
SIS 1-Inch Micro Cryo-Trap
(Model 971/981)1-inch micro cryo-traps for cryo-cooling and heating (cryo-focusing) of volatiles and semivolatiles at the head of GC capillary columns.
SIS 2-Inch CryoTrap for the AutoDesorb® System and TD5 CryoTrap for the AutoDesorb System
Applications
- Thermal Desorption Sample Trapping
- Purge and Trap Systems

Theory/Notes
Sizes
- 4-inch cryo-trap - 4" long. For high flow applications (1 to 50 mL/min). Variety of Custom I.D.'s Available.
- 1-inch ("micro") cryo-trap - Only 1" long. Best for Microbore GC Capillary Columns. Easily installs inside GC Oven without interfering with column connectors. Uses smallest volume of cooling gases.
- 2-inch cryo-trap for the AutoDesorb - TD5 Thermal Desorption.
