Self-regenerating purifier for chromatography gases

26th April 2016

Posted By Paul Boughton


Asynt has introduced GasTrap gas purifiers for analytical laboratories using Gas Chromatography (GC), High Performance Liquid Chromatography (HPLC) or Mass Spectrometry (GC/MS) instrumentation.

Gas purity is essential in any GC, HPLC or GC/MS application requiring high sensitivity. Available in optimised models for Helium, Hydrogen, Nitrogen and pure air - GasTrap gas purifiers dramatically reduce the levels of contaminants, enhance the purity of lower grade helium, and help ensure instrument stability, reproducibility as well as lowering running costs.

Laboratory gases for GC, HPLC and GC/MS are typically supplied in pressurised cylinders that contain trace impurities. Even with speciality high purity gas supplies trace contaminants of up to 20ppm Oxygen, water, Carbon Dioxide, Neon and Argon are present which increase proportionately as the cylinder pressure drops.

Unlike disposable gas filters that are time consuming, costly and cannot remove gases such as Neon, Argon or Nitrogen, based upon patented Pressure Swing Adsorption (PSA) technology - GasTrap gas purifiers remove all of contaminant trace gases and self-clean every cycle.
