Determination of cymiazole residues in honey by liquid chromatography.

A liquid chromatographic method is described for the determination of cymiazole residues in honey. This acaricide is determined on a reversed-phase (C18) column, with a CH3CN-0.001N HCl-NaCl mixture (950 mL + 50 mL + 0.

High-performance liquid chromatographic determination of dinitroaniline herbicides in soil and water.

A high-performance liquid chromatographic method for the simultaneous determination of the dinitroaniline herbicides dinitramine, ethalfluralin, trifluralin, pendimethalin and isopropalin in soil and surface water is reported. The soil was extracted with diethyl ether and analysed without any clean-up. The water was analysed after purification and concentration on a C18 cartridge.
