HPLC Separation of Citrulline and Arginine

               
Citrulline and Arginine are α-amino acids that differ only in one functional group. They can be separated on a reverse-phase Primesep 200 HPLC column by hydrophobic and cation-exchange mechanisms in a mobile phase of water and acetonitrile (MeCN, ACN) with a gradient buffer of formic acid. Evaporative Light Scattering Detector (ELSD) used.
