Oxygen Traps

High-capacity - can remove 3.5 g of O2 • Exceptional efficiency - less than 10 ppbv oxygen concentration at the outlet High capacity oxygen trap, for long term protection of capillary column stationary phases against oxidation at GC operating temperatures. 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 1% oxygen. The Model 1000 oxygen trap 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. Maximum flow rate for nominal pressure drop is 1 liter/min; maximum pressure is 69 bar (1000 psig). Approximate dimension: 5 x 37 cm with fittings. Weight is 1.2 kg. Regenerable with hydrogen treatment; instructions included. Note that sulfur compounds permanently poison the adsorbent.
