The operation of the device for the purification of argon and other inert gases "Inerta 50" is based on the process of high-temperature destruction of oxygen-containing, hydrogen-containing, as well as carbon and nitrogen-containing compounds with their subsequent absorption by temperature-activated sorbents and molecular sieves.
The device is intended for the preparation of gases used in technological installations and rooms, sealed chambers (boxes), gas chromatographs, emission and absorption spectrometers and other research and production equipment with high requirements for the quality of an inert gas used as: a protective environment for a plasma-forming, sample-carrying or shielding gas.
INERTA 50 provides a deep degree of purification of inert gases (Argon, Helium, Neon, Krypton) thanks to a highly efficient three-stage system for the absorption of impurity substances. The residual level of inert gas contamination at the outlet is less than 1 ppm.
There is a possibility of supplying INERTA 50 in a version for nitrogen purification. In this case, the absorber cartridge, which is responsible for cleaning the gas from nitrogen and oxygen, is replaced by an absorber cartridge, which removes only oxygen from the gas.

Note: when using a device for additional purification of dirtier welding, for example, argon "B" (99.95% argon and 0.05% contaminants) to the level of spectrally pure 99.998% argon (99.998% argon and 0.002% contaminants) significantly ( more than an order of magnitude), the resource of absorbing cartridges decreases. As a result, the profitability of the installation is significantly reduced. Please note that the given example is by no means a recommendation for the use of this grade of argon, but only illustrates the irrationality of using welding argon for spectral analysis in conjunction with argon post-treatment units!
