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.
Applications include
- Thermal Desorption Sample Trapping
- Purge and Trap Systems
- GC Headspace Sample Analysis
- Multi-dimensional GC applications
- Improve Chromatographic Resolution of Early Eluting Peaks
