[Determination of sulfonamides in livestock products and seafoods by liquid chromatography/tandem mass spectrometry using glass bead homogenization].
A simple and rapid method using liquid chromatography coupled with tandem mass spectrometry (LC/MS/MS) was developed for the determination of 25 kinds of sulfonamides in livestock products and seafoods. The sulfonamides were extracted with acetonitrile by glass bead homogenization and cleaned up with a tandem-connected ODS and basic alumina column. The quantification limits of 25 kinds of sulfonamides were 0.0025-0.005 microg/g. When two sulfonamides of specific samples were excluded, the recoveries and relative standard deviations were 70 to 120% and less than 15%. These results show that the developed method, which minimizes the matrix effect, offers high precision and should be useful for the determination of sulfonamides in livestock products and seafoods.
