Product Description:
Cleanert NH2 (amino) is an amino propyl extraction column based on silica gel. It has a polar stationary phase and a weak anion exchanger, which can achieve retention through weak anion exchange (aqueous solution) or polar adsorption (non-polar organic solution), thus having a dual effect. When used in non-polar solutions (such as n-hexane) for pretreatment, it can react with - OH, - Molecules with NH or - SH functional groups form hydrogen bonds. Amino pKa=9.8; The interaction with anions is weaker than that of SAX. In aqueous solutions with pH<7.8, it can be used as a weak anion exchanger to remove strong anions such as sulfonic acid ions from the sample.
