The development of a new drug substance and its dosage forms demands the establishment and implementation of suitable analytical methods. Through the application of chemometrics, "intelligent" laboratory systems and integrated data handling systems, considerable progress is being made in automating both the development and routine use of analytical methods in pharmaceutical analysis.
An optimised high-performance liquid chromatographic separation developed for the assay of tioconazole and its potential impurities has been applied to real-world samples where tioconazole is in excess. As severe peak tailing interferes with the assay of two of the impurity peaks, changes in detection wavelength have been examined as a means to discriminate between this interference. The resulting enhancement of resolution has been exploited in the optimisation of analysis time.
