Oxygen Traps

Oxygen is the leading cause of column degradation. These oxygen traps use a copper-based catalyst to remove oxygen to sub-ppm levels.



The Model 1000 high capacity oxygen trap is specifically designed for the bulk removal of oxygen for capillary use, especially with ECD and GC-MS systems.

NOTE: The active catalyst in this high capacity oxygen trap becomes hot when exposed to air. According, this Trap MUST ship as HAZARDOUS GOODS.

  • Over 2.5 liter O2 capacity from 500cc's of adsorbent
  • Removes O2 to less than 70ppb oxygen levels at the outlet
  • Nickel plated steel construction rated to 1000psig
  • Maximum flow of 1L/min recommended
  • Can be regenerated (instructions are included)
  • Delivered filled with high purity helium - ready for use
  • Approx. dimensions: 5 x 37cm
