  • A Guide to HPLC and LC-MS Buffer Selection

    BufferSelection.pdfIf a low-pH mobile phase is all that is important, 0.1% v/v phosphoric acid (Table 2) provides reasonable buffering at pH 2 for LC-UV applications. Trifluoroacetic acid (TFA) also generates a mobile phase pH of ≈2 at 0.1% v/v (Table 2), and for many years was the additive of choice for LC-MS at low pH.
