Our Cryo Traps purify the helium carrier gas being supplied to a Gas Chromatograph (GC) significantly improving the GC performance especially for PPM or PPB analysis. The Cryo Trap Purifier uses an activated carbon or molecular sieve bed immersed in a liquid nitrogen bath. It will remove impurities by freezing and plating out contaminants on the bed material. The helium will not freeze out and continue to flow to the gas chromatograph providing better analysis.
The gas purifier uses low temperature deposition of impurities in Helium to trap out gases such as Nitrogen, Argon, and CO2 as well as trap out moisture and hydrocarbons
This is a simple, low cost, highly effective way to increase the purity level of the helium carrier gas
Will purify helium to a very low PPB level of contaminants providing a good background gas as close to zero as possible for better analysis results
The purifier bed material can be regenerated to allow years of use without media replacement
Each unit is shipped fully assembled and pre-tested.
