Confirmation of Identity by Gas Chromatography/Tandem Mass Spectrometry of Sulfathiazole, Sulfamethazine, Sulfachloropyridazine, and Sulfadimethoxine from Bovine or Swine Liver Extracts after Quantitation by Gas Chromatography/Electron-Capture Detection
Autor: James A Sphon, Jean E Matusik, Richard S. Sternal, Charlie J Barnes
Publikováno v: Journal of AOAC INTERNATIONAL. 73:529-533
Four sulfonamide veterinary drug residues were quantltated by electron-capture detection (ECD) after separation by gas chromatography (GC). The Identities of sulfathiazole (ST), sulfamethazine (SM), sulfachloropyridazine (SCP), and sulfadimethoxine (
