YMC-Pack NH2

YMC-Pack NH2 Analytical HPLC Columns

YMC-Pack Amino is frequently used for the analysis of mono-, oligo- and polysaccharides as the amine functionality provides retention and allows the separation of polar compounds under aggressive normal phase elution conditions (acetonitrile/water eluents). They can also be used in place of silica for conventional normal phase chromatography using non-polar solvents. YMC-Pack Amino can also be used for the separation of isomers of tocopherols and other organic soluble compounds such as paraffins, olefins and aromatics under conventional normal phase conditions. In aqueous, low pH buffers the amino phase becomes a weak anion exchanger capable of separating negatively charged molecules.
