ʻO NH2 (amino) he kolamu hoʻoheheʻe aminopropyl me ka gel silica. Loaʻa iā ia ka nāwaliwali polar stationary phase a me ka anion exchanger, ma o ka hoʻololi anion nāwaliwali (aqueous solution) a i ʻole polarity adsorption (non-polar organic solution) e hiki ai i ka hopena, no laila he ʻelua kuleana. I ka hoʻomākaukau ʻana me nā haʻina nonpolar, e like me ka n-hexane, hiki iā ia ke hana i nā paʻa hydrogen me nā molekole me -oh, -nh a i ʻole -sh, a me amino PKa= 9.8; ʻoi aku ka nāwaliwali o ka hopena o ka anion ma mua o ka SAX, a ma PH < 7.8 aqueous solution, hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻololi anion nāwaliwali, hiki ke hoʻohana ʻia e wehe i nā anion ikaika e like me ka sulfonic acid i ka hāpana.
ʻO ka aminopropyl bond he polar adsorbent i nā nonpolar organic solutions a he nāwaliwali ka paʻa ʻana o ka anion-exchange i loko o ka wai.
