A different vital factor will be the mobile phase pH since it can change the hydrophobic character on the ionizable analyte. Because of this most solutions make use of a buffering agent, for instance sodium phosphate, to manage the pH. Buffers serve various needs: Charge of pH which affects the ionization state from the ionizable analytes, impact the charge on the ionizable silica area on the stationary period in between the bonded phase linands, and occasionally even work as ion pairing agents to neutralize analyte cost.
