zeolite molecular sieve is
a cubic lattice of an aluminosilicate compound having. Molecular sieve
has a uniform porous structure, the diameter of its pores of uniform
size, these cavities can adsorb molecules smaller diameter than the
internal bore, and an unsaturated polar molecules and molecules having a
preferential adsorption capacity, and thus able to very different
degree, different degree of saturation, and boiling points of different
molecular sizes of different molecules separated, that has the effect of
"screening" elements, so called molecular sieves. Since the molecular sieve dryer have a high adsorption capacity, high thermal stability other adsorbents that are not so widely applied molecular sieve.
In the field of biological macromolecules, a common bio-rad SEC sieve prepacked columns.
US
scientists have found that by adjusting the temperature, to precisely
control one titanium silicate material pore size, to create a
sophisticated molecular sieve. Some internal crystal material has a
large number of uniform pore size smaller than the molecules can pass
through the holes, while large molecules can not pass through, and thus
serves to separate different 4a molecular sieves , such materials are known as molecular sieve.
