A comparison is made between the use of aluminium oxide and non-modified silica gel as cation-exchange materials for the separation of basic drugs (amines) with aqueous solvent mixtures. The retention behaviour of the amines is studied and appears to be controlled predominantly by the pH and the concentration and nature of the modifier; the nature and concentration of the competing ions and the buffer components of the mobile phase also exert some influence on the retention. Preparations with imidazoline and tetracycline derivatives have been analysed as examples of the application of these ion-exchange systems on non-modified silica gel and aluminium oxide in the analysis of pharmaceutical formulations.
