A getter-based purifier for light hydrocarbon measurements

The PureGas reduces outlet impurity levels for oxygen, moisture, carbon monoxide, carbon dioxide, hydrogen, methane and nitrogen to low parts-per-billion (ppb) levels or below. The patented getter alloy, operated at elevated temperatures, removes impurities by forming irreversible chemical bonds. When the purifier is operated within specification, these impurities will not be released under any circumstances.

The benefits of getter-based purification

The PureGas is designed to further purify inert sample gases which already have a minimum purity of less than 10 parts per million (ppm).

Stable operation

The PureGas’s deep blue anodized exterior maintains a 45oC (113oF) surface temperature. The unit has efficient ceramic fiber insulation with an encapsulated heater coil. It is designed to operate continuously, without the need for servicing, throughout its rated capacity as long as the gas flowing is the carrier gas.

Reliable getter technology

When gas molecules strike the PureGas’s getter material, they combine with it chemically or by absorption, removing small amounts of gas from the evacuated space. No moving parts are required.

The right fittings for your needs

The purifier arrives fully assembled with either 1/8 compression fittings or Vacuum Coupling radiation (VCR) fittings available, depending on your purity needs. Purity levels from … <10ppb to <1ppb.

Standard Features

  • Deep blue anodized exterior maintains a 45oC surface temperature
  • Efficient ceramic fiber insulation with encapsulated heater coil
  • 20 μm sintered filter on inlet and outlet
  • 1/8” compression fittings (Optional 1/8” VCR)

The PureGas purifies inert gases such as argon, helium, neon xenon, and krypton, using a getter alloy to remove a range of impurities from the sample gas.
