Flow injection determination of ergonovine maleate with amperometric detection at the Kel-F-graphite composite electrode.
The Kel-F-graphite electrode was used for the electrochemical detection of ergonovine maleate in a flowing stream. It was found useful in the analyte concentration range 0.5-20 mug ml , with a detection limit of 50 ng ml (1.1 x 10(-7)M). A procedure was developed for assay of ergonovine maleate in tablets, and the results obtained agreed with those given by the official U.S. Pharmacopeia method.
