WebMar 1, 2007 · Peaks do split when the analyte pKa is close to the mobile phase pH. This happens when there is inadequate buffering capacity. The sample is at a pH that elutes earlier than the mobile phase and some of it runs ahead until the mobile phase catches up. This is a variation on the "strong solvent" effect.
