HPLC Separation of Dopamine and Epinephrine in HILIC and Cation-Exchange Modes

chr_305.gif

Dopamine and epinephrine were separated on a Primesep S2 HILIC mixed-mode column. Dopamine and epinephrine are retained by HILIC and cation-exchange mechanisms. Retention time is controlled by the amount of ACN, buffer and buffer pH. Method is compatible with LC/MS and can be used for analysis of polar metabolites in biofluids.
