Type MS – Molecular Sieve
Molecular sieves respectively Zeolites are alumino-silicates, metal crystalline structure. In comparison with other adsorbing agents they vary according to defined pore size. These molecular sieves adsorb selectively, ie. only adsorb molecules of defined size, the other adsorption is excluded, since not pass through the pores. Molecular sieves are still good adsorption capacity even at high temperatures and low relative humidity. When drying is achieved by a very low residual moisture (less than 1 ppmv).
