GAS PURIFIERS - FROM CRS
Advanced Filter System:  All NEW from CRS, this 2-part Advanced Filter System includes a small stainless steel manifold and a high capacity filter cartridge.
Oxygen Traps:  Oxygen is the leading cause of column degradation.  These oxygen traps use a copper-based catalyst to remove oxygen to sub-ppm levels.
Moisture Traps:  Water which can be present in the carrier gas stream can hydrolyze common silanized supports which leads to stationary phase degradation.
Moisture/Oil/Dust Traps: These traps are ideal for general purpose filtering such as fuel gases for FID's.
Hydrocarbon Traps:  These traps use activated charcoal to remove all hydrocarbons except methane.  Some hydrocarbon traps are available with Indicating Drierite^TM for simultaneous water removal.
Specialty Traps:  The Split Vent Trap keeps detector emissions from contaminating your laboratory air.
