Carbon Molecular Sieve

Carbon Kwayoyin cuta ta siee suna amfani da sifa mai sihirin da za su cimma rabuwa da oxygen da nitrogen. Babban bangaren shine carbon na asali, tare da baƙar fata mai kauri mai ƙarfi (diamita 1-2mm, tsayi 2-5mm). Saboda kasancewar babban adadin micropores (tare da diamita na 4 angstroms) tare da ƙaƙƙarfan kusanci ga kwayoyin oxygen, yawanci ana amfani da su don ware iskar oxygen da nitrogen daga iska, sa'an nan kuma samar da nitrogen ta hanyar na'urar adsorption na matsa lamba.
