One more significant component is definitely the cellular phase pH as it can alter the hydrophobic character of your ionizable analyte. For this reason most strategies make use of a buffering agent, such as sodium phosphate, to control the pH. Buffers serve various purposes: Charge of pH which influences the ionization condition in the ionizable an
