Carbon Dioxide Trap

  • Removes carbon dioxide from inert gases He, Ar, N2, H2, and clean dry air (CDA) to low ppb levels.
  • Functions by consuming carbon dioxide in a reaction with highly dispersed NaOH on a silicate support (reaction produces water that remains adsorbed in the purifier).
  • In highly critical applications, consider using an additional moisture trap after the CO2 trap as a safety measure.

Indicating Moisture Trap

  • Reduces water to less than 10 ppb. Indicator changes from yellowish green to blue at 5% relative humidity (suitable for general use).
  • Pre-purged for fast stabilization.
  • Reduces noise from high-sensitivity detectors.
  • Heavy-walled glass body prevents oxygen and water infusion.
  • 10 μm frit prevents microparticulate damage to needle valves and flow controllers.
  • Maximum operating pressure: 100 psi (689 kPa).

Indicating Oxygen Trap

  • Removes oxygen to low ppb levels from He, Ar, N2, or methane.
  • Indicator changes from green to gray when adsorption capacity is depleted.
  • Can be used with nonoxidizing gases such as He, Ar, N2, H2, or CH4.
  • Heavy-walled inner glass tube is protected by a sealed outer plastic tube to prevent oxygen and water infusion.
  • Prepurged for fast stabilization.
  • 100 psi (689 kPa) maximum operating pressure.
  • Reduces oxygen to 100 ppb.
  • 10 μm frits at inlet and outlet.
  • Optimal flow rate: < 150 mL/min.

Indicating Detector Gas Purifier

  • Removes moisture and hydrocarbons (C5 and heavier) from dry air or inert gases.
  • Indicator signals breakthrough by changing from yellowish green to blue at low relative humidity to warn of leaks in the gas stream.
  • The inner glass tube contains activated carbon, moisture indicator, and molecular sieve.
  • 10 μm frits at both ends of the filter.
  • Heavy-walled inner glass tube is protected by a sealed outer plastic tube to further protect against leaks.
