AB  - A rapid, sensitive and effective supercritical fluid chromatographic-tandem mass 
      spectrometry (SFC-MS/MS) method was developed to analyze thiacloprid for the 
      first time. The SFC-MS/MS conditions were optimized with the ultra-performance 
      convergence chromatography (UPC(2)) BEH column (100 mm x 3.0 mm, 1.7 mum particle 
      size) and thiacloprid was eluted at 1.22 min in gradient mode with CO(2)/methanol 
      as mobile phase. The 0.1% formic acid in methanol (v/v) was used as postcolumn 
      compensation solution to improve sensitivity. The ABPR pressure, flow rate of 
      mobile phase and flow rate of compensation pump were set at 1800 psi, 1.8 mL/min, 
      and 0.1 mL/min, respectively. The average recoveries of thiacloprid in soil at 
      four spiking levels (5, 10, 100, 1000 mug/kg) ranged between 78.8% and 107.1% with 
      relative standard deviations (RSDs) lower than 12.2% and the limit of 
      quantitation (LOQ) was 5 mug/kg. The proposed method can distinctly improve the 
      analysis efficiency by 2-12 times and reduce the solvent consumption by 5%-95% 
      compared with reported methods. It was applied to investigate the dissipation 
      rates of thiacloprid in greenhouse vegetables and soil under different 
      application modes. The half-lives of thiacloprid in cucumber and soil were 
      9.55-20.44 days and 3.74-9.14 days separately under different application modes, 
      10.60 days in tomato under foliar spraying. The residues in vegetables under root 
      irrigation were all less than that under foliar spraying. The results could offer 
      useful data for risk assessment of thiacloprid in agricultural production.
