NH2 SPE
I-B & M NH2 (i-amino) yikholomu yokukhutshwa kwe-aminopropyl kunye nejeli ye-silica. Inobuthakathaka be-polar stationary phase kunye ne-anion exchanger, ngokusebenzisa i-anion exchanger ebuthakathaka (isisombululo samanzi) okanye i-polar adsorption (isisombululo se-organic non-polar) ukufikelela kwisiphumo, ngoko ke inendima emibini. Xa kulungiswa kunye nezisombululo ezingezizo, ezifana ne-n-hexane, inokwenza iibhondi ze-hydrogen kunye neemolekyuli ezine-oh, -nh okanye -sh, kunye ne-amino PKa = 9.8; I-7.8 isisombululo se-aqueous, sinokusetyenziswa njenge-arhente yokutshintshiselana kwe-anion ebuthakathaka, engasetyenziselwa ukususa i-anion enamandla njenge-sulfonic acid kwisampuli.
Ibhondi ye-aminopropyl i-adsorbent ye-polar inamandla kwi-nonpolar organic solutions kwaye inokugcinwa kwe-anion-exchange ebuthakathaka kwisisombululo esimanzi.NH2 isebenza kakuhle kwiintlobo zesampulu zesampulu kwaye ingasetyenziselwa ukutya, indawo, amayeza kunye neyeza.
