CRS ZPure™ 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.

Features and benefits

High efficiency in-line traps with outstanding capacity.
High quality activated adsorbents for long purifier life and efficient contaminant removal.
Various size and fitting configurations to fit existing installations.
Filter lifetime is dependent on quality of incoming gas, and the flow rate.
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).

1) Oxygen capacity is a function of flow rate - the nominal oxygen capacity is determined using the nominal flow rate. The maximum oxygen capacity is determined using 30% of the nominal flow rate.
2) The nominal water capacity is determined for an inlet impurity level of 200 ppm H₂O. The maximum water capacity is determined for an inlet impurity level of 10000 ppm H₂O.
3) The nominal hydrocarbon capacity is determined for an inlet impurity level of 500 ppm pentane. The maximum hydrocarbon capacity is determined for an inlet impurity level of 2300 ppm pentane.
4) Nominal flow rate is the recommended flow rate for an estimated gas purifier life of 1 year. This assumes the following inlet impurities: 1 ppm O₂, 1 ppm H₂O, and 1 ppm HC (C5 and heavier). The maximum recommended flow rate is recommended for intermittent use only.
