Individual Gas Purifier Selection
The Moisture trap removes water from inert gases, air or hydrogen to less than 20 ppb at flow rates up to 2 L/min. The trap has a capacity for water of 15 g.
The Hydrocarbon trap removes C5 weight and heavier hydrocarbons from inert gases, air or hydrogen to low ppb levels. It has an impervious outer stainless steel casing.
• Huge 2.5 L capacity; reduces O2 to low ppb levels.
• Advanced adsorbent technology.
• Outstanding efficiency in a small, high performance design.
• Recommended for GC/MS carrier gas.
Provides an extra large 2.5 L capacity for oxygen removal for long term purifications. May be used in any application requiring zero-grade oxygen-free gas.
The Indicating O2 Trap 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 Indicating Oxygen Trap is recommended as a downstream indicator for high-capacity oxygen traps. It can be used with non-oxidizing gases such as He, Ar, N2, H2 or CH4. The adsorbents 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.
