HPLC Analysis of Citrulline and Arginine on Primesep Columns

Two underivatized amino acids, citrulline and arginine, are separated by mixed-mode chromatography on Primesep 100 and Primesep 200 HPLC columns with LC/MS compatible mobile phase. Method can be used for retention and separation of underivatized amino acids without ion-pairing reagent in the mobile phase.
