Abstract
The paper describes the analysis of nine sulfonamides, chosen as the most widely used representatives of an important class of antibacterial drugs. Atomic emission detection has been found to allow simultaneous quantification and identification of the N 1-methylated derivatives, which are resolved efficiently by conventional capillary gas chromatography. Results are given concerning the linearity of the response and the characterization of the individual compounds by the elemental ratio of their carbon, nitrogen and sulfur content. The method looks promising for the quantitative analysis and confirmation of sulfonamide residues in complex mixtures.
