THE SIGNIFICANCE OF DIFFERENT CHROMATOGRAPHIC METHODS IN THE EUROPEANPHARMACOPEIA

The usage frequency of chromatographic methods has been analyzed on th e basis of 1008 monographs of the European Pharmacopoeia. Using this d atabase the 'popularity-order' of the main chromatographic techniques was compared in the pharmacopoeial analyses and in the analytical lite rature of the world. It was established that the application order of the three leading chromatographic techniques in this somewhat special field of analyses is contrary to their position in the analytical lite rature of the world. The trend-analysis has shown that this discrepanc y will be weakened in the future.
