NH2 (amino) is aminopropyl extraction column ine silica gel. Iyo ine isina kusimba polar stationary phase uye anion exchanger, kuburikidza isina simba anion exchange (aqueous solution) kana polarity adsorption (isina-polar organic solution) kuti isvike pamhedzisiro, saka ine basa rehuviri. Paunenge uchigadzirira nenonpolar solutions, senge n-hexane, inogona kuumba hydrogen bonds nemamorekuru ane -oh, -nh kana -sh, uye amino PKa = 9.8; Mhedzisiro yeanion haina simba kupfuura yeSAX, uye muPH 7.8 aqueous solution, inogona kushandiswa seasina simba anion exchange agent, iyo inogona kushandiswa kubvisa anion yakasimba yakadai se sulfonic acid mumuenzaniso.
Iyo aminopropyl bond yakasimba kwazvo polar adsorbent mune nonpolar organic solutions uye ine isina simba anion-exchange retention in aqueous solution.NH2 inoita zvakanaka mumhando dzakasiyana-siyana dzesample substrates uye inogona kushandiswa mukudya, zvakatipoteredza, mishonga yemishonga uye mishonga.
