In a wide ph range
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.
