CRS ZPure™ Glass PolyGas gas purifiers

Find out more about Chromatography Research Supplies (CRS), now part of the Trajan family of brands.

Pure gas is a critical requirement in gas chromatography, spectroscopy, optics, lithography, and numerous other applications in manufacturing and analytical laboratories. The ZPure™ PolyGas purifiers remove a wide range of contaminants to trace levels. It can be used as a stand alone filter or to provide end-point detection.

Features and benefits

High efficiency in-line traps with outstanding capacity.
High quality activated adsorbents for long purifier life and efficient contaminant removal.
Filter lifetime is dependent on quality of incoming gas, and the flow rate.
Highly sensitive indicators.
Double safety seal and individually leak-tested.

Recommended applications

It can be used to purify inert gases, He, Ar, N₂, and H₂, making it ideal for use with GC and GC/MS carrier gas lines. It is also recommended for any application requiring ultra-pure gas free from oxygen, water and hydrocarbons (heavier than butane).
