✦ Synopsis

Abstract

The pyrograms of 14 sulfonylureas, i.e. herbicides characterized by high biological activity and low application dose are discussed and the mass spectra of over 30 relevant pyrolysis products as obtained with a heated filament pyrolyzer interfaced to a capillary gas chromatograph/ion‐trap detector mass spectrometer are presented. Such a data compilation is useful for diagnostic purposes for both intact suflfonylureas and their metabolites after degradation in soil, because metabolites and pyrolysis products are often identical and most of their mass spectra are lacking in commercially available mass spectral libraries. The performance of the ion‐trap detector based on the quality of the mass spectra is briefly discussed.
