Purespark Argon Purifier

Designed and manufactured in Germany

The rare gas purification system for any type of optical emission spectrometers

The rare gases are obtained from using different methods and afterward transfer to tankers or cylinders to distribute among various applications. The inert gases in every step of production, transfer and distribution might be contaminated by oxygen, nitrogen, moisture, or other impurities.

More than 30 years of experience on 2000 arc/spark optical emission spectrometers and vacuum chambers led to develop the purification system to remove argon gas impurities as an independent portable system at the consumption point for any application which requires high purity of argon gas.

Purespark argon purifier is used to meet the requirementsof metallurgy laboratories for spark optical emission spectrometry for the metal analysis, inductively coupled plasma analysis and gas chromatography analysis as carrier gas with high purity, flushing/filling vacuum chambers for keeping at near atmospheric pressure and the 3D metal printing process which takes place in an inert protective gas atmosphere for manufacturing metallic components made of titanium alloy.

Principle & Process

The argon gas purifier equipped with two independent furnaces each of which has a specific and separate function.

The main impurities in argon gas such as oxygen, nitrogen, hydrocarbons, carbon monoxide and hydrogen absorb at temperature between 450°C and 800°C by furnace one. The chemical reactions occur through 2 in 1 absorbent tube which contains zirconium + aluminum-oxide.

The moisture and carbon dioxide absorb at the ambient temperature by the molecular sieve tube. The moisture absorbent tube is embedded in second furnace which makes the regeneration process possible for many times.

Control panel

Automatic temperature controller consists of thermocouples and thermal sensors which grant multiple safety alarm levels.

The LCD indicator displays the temperature of each furnace at every second.


Quick connect couplings made of 316L stainless steel provide secure sealing for purification system.

Just push the plug into the socket for simple and safe connection. This reduces connection time and avoid any leakage.


High volume of absorbent tubes increased the capacity of removing impurities.

The lifetime of absorbent tubes estimates 5 years continuously by following Greensilver recommended rules.
