CRS ZPure™ HC (Hydrocarbon) gas filters

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™ line of filters 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 remove hydrocarbons heavier than butane from inert gases, He, Ar, N₂, H₂, and clean dry air (CDA) to low ppb levels. It is recommended for most applications requiring hydrocarbon-free gas.

Product specifications

ZPure HC
Volume	Function	Capacity (nominal-max)	Outlet concentration at nominal flow rate	Flow rate (nominal-max)	Max pressure	Dimensions	Fittings
130 cc	Removes hydrocarbons (C5 and heavier)	11 - 36 g	< 5 ppb	1 - 10 SLPM	68.9 bar / 1000 psi	3.2 cm x 28 cm	1/8" and 1/4" brass and stainless steel compression
475 cc		40 - 131 g		3.7 - 36 SLPM	68.9 bar / 1000 psi	3.8 cm x 57 cm
500 cc		42 - 137 g		3.8 - 38 SLPM	13.8 bar / 200 psi	5 cm x 35 cm
750 cc		63 - 206 g		5.8 - 57 SLPM	13.8 bar / 200 psi	5 cm x 50 cm

1) The nominal hydrocarbon capacity is determined for an inlet impurity level of 500 ppm pentane.
2) The maximum hydrocarbon capacity is determined for an inlet impurity level of 2300 ppm pentane.
3) The 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 hydrocarbons (C5 and heavier)
4) The maximum recommended flow rate is recommended for intermittent use only.
