Evaluation and Application of Stationary Phase Selectivity for Drug Analysis [PDF]
Despite the wide range of HPLC stationary phases available for reversed-phase high-performance liquid chromatography (RP-HPLC) and the in-depth studies using probes to highlight differences between them, there is very little in the way of stationary ...
