Manufacture of High Purity Gases
Synthetic air, N2, O2, H2, noble gases, etc. are typical industrial gases which are often required in high purities.
By using HeraPur® catalysts all common impurities, such as H2, O2, CO and hydrocarbons can be removed efficiently even at low temperatures. In many cases the residual concentrations of the impurities amount to only a few ppb.
