"Online Photochemical Derivatization And Flow Injection Spectrophotometric Determination Of Ergonovine Maleate"
Anal. Chim. Acta 1993 Volume 282, Issue 1 Pages 95-100
A. Mellado Romero and G. Gomez Benito, J. Martínez Calatayud

Abstract: A stream of sample solution was merged with a stream of 8.4 mM 4-dimethylaminobenzaldehyde (I)/89.5 mM Fe(III) in 30% H2SO4 (both at 2.05 ml/min) and the mixture was passed into a cell (2008 µL) in which it was irradiated with a Hg lamp under stopped-flow conditions for 1 min. The mixture was then transported to the flow cell by a carrier stream of 4.2 mM I/44.7 mM Fe(III) in 30% H2SO4 (4.85 ml/min) and the absorbance was measured at 542 nm. The calibration graph was rectilinear for 3-74 µg/ml of ergometrine. The RSD (n = 7) at 29 µg/ml was 1.7% and the sample throughput was 34/h.

"Flow Injection Determination Of Ergonovine Maleate With Amperometric Detection At The Kel-F-graphite Composite Electrode"
Talanta 1986 Volume 33, Issue 5 Pages 448-450
F. Belal* and J. L. Anderson

Abstract: Tablets containing ergometrine maleate(I) were powdered and dissolved in the mobile phase [methanol - 0.01 M phosphate buffer - 2% Na acetate (pH 7) (1:4)] and subjected to flow injection analysis with amperometric detection with a Kel-F - graphite electrode at +0.85 V vs. silver - AgCl. The calibration graph was rectilinear for 1 to 20 µg mL-1 of I and the detection limit was 50 ng mL-1. The coefficient of variation were 1%, and the results agreed well with those obtained by the official USP method.
