Abstract
The influence of different laboratory set-ups on HPLC retention index values of selected acidic and basic drugs was investigated. The RI values of drugs were calculated using the alkyrarylketone scale. Two columns filled with different batches of the same Hypersil ODS phase were consecutively used in two laboratories under identical conditions, but using different instrumentation. The study showed that the different laboratory set-ups influence the precision of RI values, and the differences in column filling affect the accuracy. Es wird über den Einfluß unterschiedlicher instrumenteller Bedingungen in zwei verschiedenen Laboratorien auf die in der HPLC mittels Alkylarylketonen berechneten Retentionsindices ausgewählte Arzneistoffe berichtet: Zwei Säulen wurden mit verschiedenen Chargen Hypersil ODS Phase gefüllt und jeweils nacheinander in zwei Laboratorien unter identischen Bedingungen aber verschiedener Instrumentenausstattung eingesetzt. Die Untersuchung zeigt, daß das Säulenfüllungsmaterial die Richtigkeit und die apparative Komponente die Genauigkeit der Retentionsindex-Werte beeinflußt.This publication has 3 references indexed in Scilit:
