Abstract 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 (SDM) were confirmed In bovine or swine liver residues by tandem mass spectrometry (MS/MS). Bovine or swine liver tissues were extracted by using either the Tlshler or the Manuel-Steller cleanup. The methylated residues containing ST, SM, SCP, and SDM were separated by GC prior to MS/MS daughter ion analysis. Control tissue, control tissue fortified at 0.1 ppm, and Incurred tissue residues at approximately 0.1 ppm were analyzed for these 4 sulfonamides. A Flnnigan Model TSQ-46 operating in the chemical ionization mode was used to perform the MS/MS daughter Ion experiments. The Identities of all 4 sulfonamides were confirmed In a single GC/MS/MS analysis.

Hardness Ratio

Absolute Extreme Ultraviolet emission cross-sections have been measured for collisions between C 5 + and H 2 O in the range of 0.113 to 3.75 keV/amu (170–979 km/s). These results are used to derive velocity-dependent triplet-to-singlet ratios and emission cross-sections of the Cv K-series following single-electron capture. Comparison with existing measurements of integral charge-changing cross-sections indicates that auto-ionizing multi-electron capture is a significant reactions channel. This reaction may indirectly populate the n = 2 states and thus add strength to the K α emission of Cv ions thereby co-determining the hardness ratio of K-series emission of Cv.
