ʻO PSA ka ethylenediamine - N-propyl extraction kolamu me ka silica gel, a he ʻelua pūʻulu amino ka PSA, a ʻo ka pKa ka 10.1 a me ka 10.9. Ua like kona koho me ka amino. Ma keʻano he kūlana maikaʻi a iʻole ke kolamu anti-phase, uaʻoi aku ka ikaika o ka polarity ma mua o ka C18 a me ka nāwaliwali ma mua o ka silica gel, aʻo nā pūhui likeʻole me ka laulā o ka medium polarity a iʻole ka polarity he koho maikaʻi i nā pūnaewele likeʻole.
Hiki ke hoʻohana ʻia ka PSA me nā ion metala e unuhi i nā ion metala. Hoʻohana pinepine ʻia ia i ka hoʻomākaukau ʻana i nā laʻana o nā koena mahiʻai, e komo pū me nā waikawa organik, nā puaʻa, nā ion metala a me nā phenols.
