*Model 1000 Oxygen Filter - 1/4" Brass Fittings

High capacity oxygen purifier for long term protection of capillary column stationary phases against oxidation at GC operating temperatures. It is also recommended for packed column carrier gases. 

The Model 1000 has a capacity of 2.5 liters of oxygen at room temperature. It 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 0.1% oxygen. It will remove oxygen to below 10 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 500 cc 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. It is ready for use, but we recommend that the purifier be purged with the gas you will be using.
