Indicating Oxygen Traps
Indicating Oxygen Traps from Agilent
This is an improved, compact indicating filter for high-efficiency oxygen removal, suitable for use with chromatography carrier gas streams. It removes oxygen to low-ppb levels, with an indicator that changes color from green to gray when adsorption capacity is depleted. The adsorbent forms copper oxide in the presence of oxygen; no gas is generated.
The Glass Indicating Oxygen Trap is recommended as a downstream indicator for high-capacity traps. It can be used with non-oxidizing gases such as He, Ar, N2, H2 or CH4, with maximum recommended flow rate of 150 cc/min. The absorbents are held in a heavy-walled inner glass tube, shielded by an outer clear plastic tube for increased safety. Maximum pressure is 6.8 bar (100 psig). Approximate dimensions are 3.5 cm x 26 cm including fittings.
Dual Seal Design: In this design the glass inner tube is protected by a sealed outer plastic tube. Even if the glass tube fails, the gas system is fully protected against leaks.
