High reputation C18 Spe - NH2 SPE – BM Life Science Detail:

B&M NH2(amino) is aminopropyl extraction column with silica gel. It has the weak polar stationary phase and anion exchanger, through weak anion exchange (aqueous solution) or polarity adsorption (non-polar organic solution) to reach the effect, therefore has a dual role. When preparation with nonpolar solutions, such as n-hexane, it can form hydrogen bonds with molecules with -oh, -nh or -sh, and amino PKa= 9.8;The effect of anion is weaker than that of SAX, and in PH < 7.8 aqueous solution, it can be used as a weak anion exchange agent, which can be used to remove the strong anions such as sulfonic acid in the sample.

The aminopropyl bond is strongly polar adsorbent in nonpolar organic solutions and has a weak anion-exchange retention in aqueous solution.NH2 performs well in a variety of sample substrates and can be used in food, environment, pharmaceuticals and medicine.

Application：

Soil;Water;Body fluids(plasma/urine etc.);Food

Typical Applications：

The strong anions, such as sulfonate, are

extracted in the pH<7.8 aqueous solution

Extraction and separation of isomers

Phenol, phenolic pigments, natural products

Petroleum fraction;Sugar;Drugs and their

metabolites
