WebThe typical pH range for reversed-phase separations on silica-based columns is between 2 to 8. The buffer must have a pKa close to the desired pH, since buffers control pH best at their pKa. As a rule of thumb, it is ideal to choose a buffer with a pKa value <2 units of the desired mobile phase pH. WebCheck the pH slope in pH 7 buffer regularly. The slope should be greater than 92% (53.5 mV/pH @ 20°C or 54.4 mV/pH @ 25°C).The offset (as measured in fresh pH 7 buffer) should be +/- 30 mV for new electrodes and +/- 59 mV for aged electrodes to enable auto-buffer recognition during calibration..
