Determination of Acephate, Dinotefuran, and Emamectin Benzoate in a Pesticide Formulation: A Single-Laboratory Validation.

Background: The advantage of simultaneous separation and quantification is the reduction of analysis time and consumption of solvents and reagents.

Objective: The objective of the present investigation was to optimize and validate a novel, rapid, and simple reverse-phase high-performance liquid chromatographic method for the simultaneous determination of acephate, dinotefuran, and emamectin benzoate in a pesticide formulation.

Method: The chromatographic separation and quantification were accomplished by using Kromasil CN column (250 mm × 4.

A novel validated simple derivatization liquid chromatographic method with diode array detection for the simultaneous determination of mancozeb, azoxystrobin and difenoconazole in pesticide dosage form.

A novel, rapid and simple reverse-phase high performance liquid chromatography (RP-HPLC) method for the simultaneous determination of three pesticides - mancozeb, azoxystrobin and difenoconazole by derivatization with ethyl iodide is presented. Analysis was performed on a C18 column (Agilent Eclipse plus, 150 mm × 4.6 mm; 5 μ) with the mobile phase consisting of acetonitrile + methanol (90 + 10 v/v) - water (0.

A simple derivatization RP-HPLC method for the simultaneous determination of zineb and hexaconazole in pesticide formulation using a PDA detector.

A simple derivatization reverse-phase high performance liquid chromatographic method for the simultaneous analysis (separation and quantification) of zineb and hexaconazole has been optimized and validated. The method was carried out on an Agilent Eclipse plus C18 column (150 × 4.6 mm; 5 μm), with a mobile phase comprising acetonitrile + methanol (80 + 20 v/v): water (0.
