I-B&M NH2(amino) iyikholomu yokukhipha i-aminopropyl enejeli ye-silica. Inesigaba esintekenteke se-polar kanye ne-anion exchanger, ngokushintshisana okubuthakathaka kwe-anion (isixazululo esinamanzi) noma i-polarity adsorption (isixazululo semvelo esingeyona indawo ezungezile) ukuze sifinyelele umphumela, ngakho-ke sinendima ekabili. Uma ulungiselela ngezixazululo ezingezona ezimhlophe, njenge-n-hexane, ingenza izibopho ze-hydrogen nama-molecule ane--oh, -nh noma -sh, kanye ne-amino PKa= 9.8;Umphumela we-anion ubuthakathaka kunalowo we-SAX, futhi ku-PH < 7.8 isixazululo samanzi, singasetshenziswa njenge-ejenti yokushintshanisa i-anion ebuthakathaka, engasetshenziswa ukususa ama-anion aqinile njenge-sulfonic acid kusampula.

Isibopho se-aminopropyl sinamandla we-polar adsorbent ku-nonpolar organic solutions futhi sinokugcinwa okubuthakathaka kwe-anion-exchange kusisombululo esinamanzi.NH2 yenza kahle ezinhlobonhlobo ze-substrates zesampula futhi ingasetshenziswa ekudleni, endaweni, emithini yemithi nasemithi.

Isicelo:
Umhlabathi;Amanzi;Uketshezi lomzimba(i-plasma/umchamo njll.);Ukudla
Izicelo Ezijwayelekile:
Ama-anion aqinile, njenge-sulfonate, akhona
kukhishwa ku-pH <7.8 isixazululo esinamanzi
Ukukhishwa nokuhlukaniswa kwama-isomer
Phenol, phenolic pigments, imikhiqizo yemvelo
I-petroleum fraction;Sugar;Izidakamizwa kanye nazo
ama-metabolites
