ABSTRACT ionic strength of mobile phase can significantly affect the peak shape of ionogenic compounds such as antibiotics in reversedphase high performance liquid chromatography. The influence may be attributed to overloading of ionogenic analytes in lower ionic strength mobile phase. In such phase, peak becomes increasingly rightangled triangle in shape with increasing sample load together with increasing peak width and tailing.
