Carbon da aka kunna: shine nau'in adsorbent mara iyaka da ake amfani da shi da yawa.Gabaɗaya, ana buƙatar wanke shi da acid dilute hydrochloric, sannan a bi shi da ethanol, sannan a wanke shi da ruwa.Bayan bushewa a 80 ℃, ana iya amfani dashi don chromatography shafi.Carbon da aka kunna granular shine mafi kyawun zaɓi don chromatography shafi.Idan yana da kyau foda na carbon da aka kunna, ya zama dole don ƙara adadin diatomite daidai a matsayin taimakon tacewa, don guje wa jinkirin gudu.
Carbon da aka kunna shine adsorbent mara iyaka.Its adsorption akasin zuwa silica gel da alumina.Yana da alaƙa mai ƙarfi ga abubuwan da ba na iyakacin duniya ba.Yana da ƙarfi mafi ƙarfi a cikin maganin ruwa kuma yana da rauni a cikin sauran ƙarfi.Sabili da haka, ƙarfin haɓakar ruwa shine mafi rauni kuma mai ƙarfi mai ƙarfi ya fi ƙarfi.Lokacin da abin da aka ƙaddamar da shi ya ɓace daga carbon da aka kunna, polarity na ƙaura yana raguwa, kuma ƙarfin adsorption na solute akan carbon da aka kunna yana raguwa, kuma ana haɓaka ƙarfin haɓakar eluent.Abubuwan da ke narkewar ruwa, kamar su amino acid, sugars da glycosides, an ware su.
