EXTENDING LIFE TIME
Generally, when a heated getter alloy based purifier reaches or gets close to its end of life, the first impurities to break through will be N2 followed by CH4. The technology allows the reduction of the N2 and CH4 load on the getter alloy by reacting them in a plasma reactor pre-stage doped with H2O. They are transformed into NOX, H2O, CO, and CO2 that are more easily trapped in an intermediate chemical trap. This way the getter alloy sees considerably less impurities and its life time is extended. As all those features can be integrated at a very low cost and in a compact design. It makes this technology a must have for every purification systems and render obsolete competing ones.
