Siffar kwayoyin halitta wani tsayayyen adsorbent ne wanda zai iya raba kwayoyin halitta masu girma dabam. Yana da SiO2, Al203 azaman silicate na aluminium crystalline tare da babban bangaren. Akwai ramuka da yawa masu girman ƙima a cikin lu'ulu'unsa, kuma akwai ramuka da yawa na diamita ɗaya a tsakanin su. Yana iya haɗa ƙwayoyin da ke ƙasa da diamita na pore zuwa cikin ramin, kuma ya ware ƙwayoyin da suka fi girma fiye da buɗewa zuwa waje, suna taka rawar sieve.
Molecular sieve yana da ƙarfin shayar da danshi mai ƙarfi, kuma kusan dukkanin kaushi ana iya amfani dashi don bushe shi, don haka ana amfani dashi sosai a cikin dakin gwaje-gwaje da masana'antu. Molecular sieve adsorption Hanyar ita ce hanyar bushewa tare da ƙarancin amfani da makamashi da inganci, tsarin yana da sauƙi, mafi dacewa da zurfin dehydration na ruwa da iskar gas, yin amfani da girman buɗaɗɗen ƙwayar ƙwayar ƙwayar ƙwayar cuta ta zaɓi adsorption na ruwa, don haka cimma rabuwa.
Ƙarfafawar thermal na sieve kwayoyin yana da kyau, wanda zai iya tsayayya da gajeren zafin jiki na 600C ~ 700C, kuma zafin jiki na farfadowa bai kamata ya wuce 600C ba, in ba haka ba zai shafi aikin sieve kwayoyin, kuma za'a iya fitar da shi (babu farfadowa na thermal). Siffar kwayoyin halitta ba mai narkewa a cikin ruwa ba, amma an narkar da shi a cikin acid mai karfi da alkali, don haka ana iya amfani dashi a cikin matsakaici na pH5 ~ 11. Molecular sieve yana da sauƙi don sha ruwa, ya kamata a rufe ajiyar ajiya, amfani ya kamata a duba ko abun ciki na ruwa ya wuce misali, ajiya na dogon lokaci shayar da danshi, ya kamata a yi amfani da shi bayan amfani, aikinsa bai canza ba. Molecular sieve yana da halaye na sauri adsorption gudun, da yawa farfadowa sau, high murkushe da lalacewa juriya, da karfi gurbatawa juriya, high amfani yadda ya dace, dogon sabis rayuwa, da dai sauransu, wanda shi ne fĩfĩta desiccant ga gas da ruwa lokaci zurfin bushewa.
