NH2 SPE
B&M NH2 (amino) bụ kọlụm mmịpụta aminopropyl nwere gel silica. Ọ nwere akụkụ na-adịghị ike pola na anion Exchanger, site na anion mgbanwe adịghị ike (aqueous ngwọta) ma ọ bụ polarity adsorption (na-abụghị polar organic ngwọta) iru mmetụta, ya mere nwere a dual ọrụ. Mgbe nkwadebe na ngwọta ndị na-abụghị polar, dị ka n-hexane, ọ nwere ike ịmepụta njikọ hydrogen na ụmụ irighiri ihe na-oh, -nh ma ọ bụ -sh, na amino PKa = 9.8; Mmetụta nke anion adịghị ike karịa nke SAX, na na PH < 7.8 ngwọta mmiri mmiri, enwere ike iji ya dị ka onye na-agbanwe agbanwe nke anion na-adịghị ike, nke a pụrụ iji wepụ anions siri ike dị ka sulfonic acid na nlele.
Njikọ aminopropyl bụ ike pola adsorbent na nonpolar organic ngwọta na-adịghị ike anion-exchange njigide na aqueous solution.NH2 na-arụ ọrụ nke ọma na a dịgasị iche iche nke sample substrates na ike ga-eji na nri, gburugburu ebe obibi, ọgwụ na nkà mmụta ọgwụ.
