  • Title: High pressure liquid chromatographic determination of methomyl and oxamyl on vegetable crops.
    Author: Thean JE, Fong WG, Lorenz DR, Stephens TL.
    Journal: J Assoc Off Anal Chem; 1978 Jan; 61(1):15-7. PubMed ID: 621190.
    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.
