Abstract
<jats:p>A fast, simple, precise and accurate reversed-phase high-performance liquid chromatography (RPHPLC)method with UV-DAD for simultaneous determination of desmedipham, phenmedipham and ethofumesate in the pesticide formulation “Inter OF” has been developed. The analysis was performed on a LiChrospher 60 RP-select B (25 cm × 0.4 cm, 5 μm, Merck) analytical column, with mobile phase of methanol/water (60/40, V/V), flow rate of 1 ml/min, UV-detection at 230 nm and constant column temperature at 25 ºC. The following parameters were determined for the developed method: retention factor, separation factor, limit of detection (LOD), limit of quantification (LOQ), precision of obtained results for peak area, linearity, recovery of analyte and active ingredients quantity in a pesticide formulation.</jats:p>
