B&M NH2(amino) ole aminopropyl extraction column with silica gel. O loʻo i ai le vaega vaivai polar stationary ma le anion exchanger, e ala i le vaivai o le anion exchange (aqueous solution) poʻo le polarity adsorption (non-polar organic solution) e oʻo atu i le aʻafiaga, o lea e iai se vaega lua. Pe a sauniuni i vaifofo e le polar, e pei o le n-hexane, e mafai ona fausia ai le hydrogen faʻatasi ma molelaʻau ma -oh, -nh poʻo -sh, ma amino PKa= 9.8; O le aʻafiaga o le anion e sili atu le vaivai nai lo le SAX, ma i le PH < 7.8 vaifofo vai, e mafai ona faʻaaogaina e avea o se sui sui o le anion vaivai, lea e mafai ona faʻaaogaina e aveese ai le malosi malosi e pei o le sulfonic acid i le faʻataʻitaʻiga.
O le aminopropyl bond o loʻo malosi faʻapipiʻi i totonu o vaifofo faʻalaʻau nonpolar ma o loʻo i ai le faʻamauina o le anion-exchange vaivai i le vai vaifofo. NH2 e faʻatino lelei i le tele o faʻataʻitaʻiga substrates ma e mafai ona faʻaaogaina i meaʻai, siosiomaga, vailaʻau ma vailaʻau.
