Chromatographic determination of phenylurea herbicides and their corresponding aniline degradation products in environmental samples. I.

Determination of phenylurea herbicides via direct derivatisation with heptafluorobutyric anhydride

Separation of six phenylureas and chlorsulfuron standards by micellar, mixed micellar and microemulsion electrokinetic chromatography

The determination of urea pesticides is difficult by means of gas chromatography because they undergo thermal decomposition when applying standardized chromatographic conditions as used in multiresidue analysis. A method is therefore described to make possible the detection of these compounds by gas chromatography after derivatization with HFBA using either electron capture and nitrogen-phosphorus detection or a mass spectrometer as detector.
