Kaasusuodattimet ,Gas purifying system

A high-capacity gas purifying system designed to reduce contaminants in gases commonly used in laboratory applications to low-ppb levels, available in two models. The AFS Purifier I removes oxygen, mositure and hydrocarbons, (greater than C4) from inert gases and hyrdogen. It contains high-sensitivity oxygen and moisture indicator. When cartridge is depleted the oxygen indicator changes from GREEN to GREY. The Moisture indicator changes from BLUE to BROWN. Both AFS Purifier I and AFS Purifier II have a very high capacity and can be expected to supply four GC’s for at least one year when used with 99.995% pure gas supplies (provided reasonable care is taken during tank changes). The Advanced Filter System Complete Kit includes the AFS Cartridge, Manifold, and the wall and bench mounting brackets.

AFS Purifiers I & II The highest quality and safest gas purifier for GC applications
Features • Very high capacity – for long life and lower operating cost • Double-seal construction for safety, especially when using hydrogen gas • Decrease baseline noise and increases GC and GC/MS sensitivity • Reduce gas contaminants to low ppb levels

FID Gases (Dry Air, Hydrogen)
The Advanced Filter System from Chromatography Research Supplies offers a high-capacity and safe technology for purifying supply gases for Gas Chromatography applications. Because of its very high capacity, the AFS also offers a low overall cost of operation for supply gas purification. With reasonable care in use, the AFS will purify approximately 45 cylinders of gas at 99.995% purity, meaning that it will only have to be changed one-tenth as often as small-cartridge systems.
The AFS comes in two versions, the AFS I for carrier gas and ECD make-up gas, and the AFS II for FID supply gases.
