Application of high-performance liquid chromatography to the determination of pesticides included in the European Economic Community Directive on fruit and vegetables

Residue determination of some insecticides and fungicides on grapes by reversed-phase high-performance liquid chromatography

“…The major advantages of HPLC have been frequently pointed out; we want to emphasize, for our field of application, the reduced cleanup in comparison to GLC and the possibility of monitoring many chemically different pesticides (carbamate or organophosphorus or organochlorine) simultaneously (Seiber, 1974). Reversed-phase HPLC, moreover, is considered likely to give most efficient separation of pesticides when the mobile phase is wateracetonitrile or water-methanol (Seiber, 1974;Hoodless, 1978;Sparacino and Hines, 1976;Aten and Bourke, 1977).…”

“…It has been successfully employed in the determination of residues of pesticides (Cabras et al, 1979a,b; Hoodless et al, 1978). So far only few HPLC simultaneous quantitative determinations of different pesticides, currently used on vineyards to control insects and fungine disease, have been reported (Lawrence and Turton, 1978).…”

A sub-second fast Fourier transform-adsorptive voltammetric technique for the nano-level determination of guthion at a gold microelectrode in flowing solutions

“…These methods are time consuming because of the lengthy extraction, column cleanup and/or derivatization steps. The HPLC procedures are not readily applicable to fruit and vegetable [10][11][12][13].…”

Development of an Experimental Plot Sprayer

“…Scientists have mounted sprayers on small vehicles such as garden tractors, all-terrain vehicles, or specially designed carriers (1,2,5). Hergert 3 designed and built a self-propelled sprayer in 1972 to meet the requirements of Agriculture Canada's weed scientists. Sprayer pres sure was provided by an air compressor mounted on the vehicle.…”
