High pressure liquid chromatographic determination of methomyl and oxamyl on vegetable crops
Journal - Association of Official Analytical Chemists
|January 1, 1978
Abstract:
A reverse phase high pressure liquid chromatographic method is presented for the separation and determination of residues of the carbamates oxamyl and methomyl on vegetables. A liquid-liquid extraction and cleanup procedure is applied to the vegetable extract. Samples are eluted from a muBondapak C18 column and quantitated by ultraviolet absorbance at 240 nm. Recovery data for vegetable samples spiked at 2 ppm are presented.
