HPLC Buffers and Reagents

Retention of ionic analytes in reversed phase HPLC (RP-HPLC) is fundamentally affected by the pH of the mobile phase. Thus, pH control of the mobile phase in HPLC is one of the most important parameters for successful separation of analytes. For this reason, high quality HPLC buffers are widely used.
