- Model 75-802 - Carrier Gas Purifier



The AGC Model 75-802 Carrier Gas Purifier ensures a stable supply of purified gas for efficiency and costeffectiveness in gas chromatography systems. The original version of this refined instrument is the Bench Mount Purifier from AGC Instruments which is easily integrated with new or existing set-ups to work in tandem with numerous applications. This configuration links seamlessly with the AGC family of Gas Chromatographs and TrendVision PLUS Chromatography Software units for a comprehensive gas analysis system.

By having a low ppb impurity level in carrier and detector gases, longer instrument life spans and better sensitivities are achieved, thus saving companies both time and money. This high quality gas is also essential for the operation of sensitive Ionisation Detectors such as the AGC Discharge Ionisation Detector (DID) and the AGC Argon Discharge Detector (ADD). These two detectors require pure Helium and pure Argon respectively.

The Model 75-802 is based on the heating of purifying pellets which have been coated with a thin oxide layer. When these pellets are heated, impurities in the gas stream passed over them are trapped. By continuously diffusing the impurities into the purifying material, a fresh reactive surface is maintained. This reaction will ensure that the output gas is produced at least 2 grades better than the input gas.
