Jaj. Garcia et al., USE OF DERIVATIVE SPECTROPHOTOMETRY IN THE RESOLUTION OF OVERLAPPED PEAKS IN LIQUID-CHROMATOGRAPHY AND ITS APPLICATION IN THE ANALYSIS OF ACTIVE COMPONENTS IN INSECTICIDE FORMULATIONS, Journal of liquid chromatography, 17(2), 1994, pp. 277-285
A procedure for the determination of active components in insecticide
formulations showing overlapped peaks in liquid chromatography has bee
n devised. The procedure is based in the use of derivative spectra of
the components obtained by a diode-array spectrophotometer around the
maxima signal of the chromatographic peak, and has been applied to the
analysis of mixtures of piperonyl butoxide, neopynamine and fenitroth
ion with satisfactory results.
