General description

This multiple bed trap removes hydrocarbons, moisture, oxygen, carbon monoxide, and carbon dioxide from helium gas streams. The amount of highly effective, high capacity adsorbent material in each bed is optimized so that breakthrough of each contaminant is as close to simultaneous as possible. This avoids the costly replacement observed with other broad-spectrum traps that have exhausted their capacity for one contaminant, but still have capacity for other contaminants. This trap will easily purify 99.997% purity helium to a cumulative level of 100 ppb (hydrocarbons + moisture + oxygen + carbon monoxide + carbon dioxide).Specifications: Output Purity: 99.99999% Output Efficiency (total): ﹤100 ppb Output Efficiency (hydrocarbons): ﹤20 ppb (as methane) Output Efficiency (moisture): ﹤10 ppb Output Efficiency (oxygen): ﹤2 ppb Output Efficiency (carbon monoxide): ﹤20 ppb Output Efficiency (carbon dioxide): ﹤1ppm Capacity (hydrocarbons): 30 g (as methane) Capacity (moisture): 46 g Capacity (oxygen): 1200mg Max. Flow Rate: 8 L/min. Max. Pressure: 500 psi Max. Temp.: 100 °CDimensions for both purifiers16.5 in. (41..91 cm) long × 2 5/16 in. (6.3 cm) diameter
