Sive molekụla bụ adsorbent siri ike nke nwere ike ikewapụta ụmụ irighiri ihe dị iche iche. Ọ bụ SiO2, Al203 dị ka kristal aluminom silicate na isi akụrụngwa. Enwere ọtụtụ oghere nke otu nha na kristal ya, ma enwere ọtụtụ oghere nke otu dayameta n'etiti ha. Ọ nwere ike ịgbanye ụmụ irighiri ihe dị ntakịrị karịa dayameta pore n'ime oghere ahụ, ma wepụ ụmụ irighiri ihe karịrị oghere n'èzí, na-arụ ọrụ sieve.
Molecular sieve nwere ikike nnabata mmiri siri ike, yana ihe fọrọ nke nta ka ọ bụrụ ihe mgbaze niile enwere ike iji kpoo ya, yabụ a na-eji ya na ụlọ nyocha na ụlọ ọrụ. Molecular sieve adsorption usoro bụ usoro akpịrị ịkpọ nkụ na obere ume ike na arụmọrụ dị elu, usoro ahụ dị mfe, dabara adaba maka mmiri mmiri mmiri na gas miri emi, ojiji nke nha nke molecular sieve aperture nhọrọ adsorption nke mmiri, nke mere na nweta nkewa.
