## Abstract Sulfonylurea herbicides have been studied using negativeβion desorption chemical ionization (DCI) mass spectrometry (MS) and DCIβMS/MS techniques. Both [M ο£Ώ H]^β^ and M^βΒ·^ ions were observed in the DCI mass spectra. The collisionally activated dissociation (CAD) spectra were characteri

Identification of sulfonylureas in serum is important in the diagnosis of hypoglycemic crisis of unknown origin. Methods based on HPLC with UV or fluorescence detection may give false positive results. Mass spectrometry may successfully avoid this problem. The described method allows the simultaneou
