HPLC Determination of Lysine on Primesep 200 column in MS-compatible conditions Chromatogramm

High Performance Liquid Chromatography (HPLC) Method for Analysis of Lysine , D-Lysine

Lysine is an essential amino acid used in the synthesis of proteins. In biological conditions, it is a basic, charged molecule. Lysine can be retained on Primesep 200 mixed-mode column which has embedded weak acidic ion-pairing groups for retention of basic analytes in HPLC. The mobile phase consisting of acetonitrile (ACN) and water with ammonium formate (AmFm) makes this method analysis MS-compatible.
