  • Title: Analysis of pesticide residues in wine by solid-phase extraction and gas chromatography with electron capture and nitrogen-phosphorus detection.
    Author: Jiménez JJ, Bernal JL, del Nozal MJ, Toribio L, Arias E.
    Journal: J Chromatogr A; 2001 Jun 01; 919(1):147-56. PubMed ID: 11459301.
    Abstract:
    A feasible and reproducible method for multiresidue analysis of several common pesticides, of different polarities, in wine samples is proposed. The method combines a solid-phase extraction on polymeric cartridges eluted with ethyl acetate and a gas chromatographic determination using electron capture and nitrogen-phosphorus detection. To avoid the matrix effect, previous washing of the cartridges with a mixture of water-2-propanol (90:10) and further clean-up of the extract on Florisil cartridges, together with a calibration using spiked extracts, are recommended.
