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 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.
