Abstract
A systematic study of the retention behaviour in a C18 reversed phase liquid chromatography (RPLC) system of several inorganic salts, namely NaNO2, NaNO3, KBr, Bu4NBr and K2Cr2O7, is presented. The behaviour of the markers in unbuffered mobile phases and the marker retention dependence on the pH and ionic strength of the buffered mobile phases have been analyzed. In addition, a comparison between the retention behaviour of the markers and several ionizable analytes in buffered eluents is presented.
