title: Isocratic multi-column high-performance liquid chromatography as a technique for qualitative analysis and its application to the characterisation of basic drugs using an aqueous methanol solvent.
abstract: A variety of high-performance liquid chromatography packing materials were prepared and their chromatographic properties compared for separating several basic drugs using a single solvent system. The three most promising packing materials (silica, a mercapto propyl modified silica and a n-propyl sulphonic acid modification) were subsequently used to provide retention volume data for a large number of drugs.
