Abstract
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.
