AB  - An analytical method based on LC-MS/MS was developed for the determination of 
      asulam in livestock products. Asulam in livestock products was extracted with 
      acetone. The crude extracts were defatted by acetonitrile and n-hexane 
      partitioning. Cleanup was carried out using a combination of ethylene 
      diamine-N-propyl silylation silica gel (PSA) and octadecyl silylated silica gel 
      (C(18)) mini columns with acidic condition. The sample solution was subjected to 
      LC-MS/MS using an external solvent calibration curve. The average recovery (n=5) 
      of Asulam from four types of livestock products (bovine muscle, bovine fat, 
      bovine liver and milk) spike at the maximum residue limits (MRLs) or at a uniform 
      limit of 0.01 mg/kg was 92.7-98.7%, with a relative standard deviation of 
      3.1-11.6%. The limit of quantitation of the developed method was calculated to be 
      0.01 mg/kg.
