Molecular Sieve Beads

Molecular sieves are synthetically produced crystalline metal alumino silicates that have been activated for adsorption by removing their water of hydration. Unlike other adsorbents, molecular sieves have a precise uniform size and molecular dimension. According to the size of these pores, molecules may be readily adsorbed, slowly adsorbed or completely excluded. This sieve-like selectivity, based on molecular size, plus a selectable preference for polar or polorizable molecules, gives molecular sieves an extremely high level of adsorption efficiency, and permits close tailoring of the adsorbent to the specific use.
