ZPure™ CO2 Filter - Metal

The ZPure CO2 Filter removes carbon dioxide from inert gases, He, Ar, N2, H2 and clean dry air (CDA) to low ppb levels. The filter functions by consuming carbon dioxide in a reaction with highly-dispersed NaOH on a silicate support. The reaction produces water which remains adsorbed in the purifier. It is available in 4 sizes of stainless steel cylinders ranging from 130cc to 750cc.

Model 1000 02 Purifier - Metal

ZPure Smodel 1000 02 Purifier

The Model 1000, O2 high capacity oxygen purifier is for long term protection of capillary column stationary phases against oxidation at GC operating temperatures. It is also recommended for packed column carrier gases. It has a capacity of 2.5 litres of oxygen at room temperature and is also effective for removing sulfur compounds, such as hydrogen sulfide and mercaptans. The Model 1000 is intended for use with non-oxidizing gases such as He, Ar, N2, H2 or CH4, containing less than 1% oxygen. It will remove oxygen to below 70 ppb from these gases at flow rates normally encountered in GC operation. The Model 1000 Oxygen Purifier is a high-pressure metal cylinder filled with 500cc of active oxygen adsorbent. The adsorbent binds covalently with oxygen; no gas is generated from this reaction. It is delivered in the active state, filled with high-purity helium

Efficiency: O2: <10ppb
