AB  - A method for the determination of ethephon, thidiazuron and diuron in cotton 
      samples has been developed by high performance liquid chromatography-tandem mass 
      spectrometry (HPLC-MS/MS). The sample was extracted with methanol-water. The 
      separation was carried out on a C8 column (150 mm x 4.6 mm, 5 microm) with 
      methanol-water (6:4, v/v) as mobile phase at a flow rate of 0.4 mL/min, and the 
      injection volume was 20 microL. Then the sample solution was analyzed by 
      HPLC-MS/MS in negative ion mode with multiple reaction monitoring (MRM). There 
      were one precursor/two product ion transitions for each pesticide. The results 
      showed that the working curves were linear in the range of 0-10 microg/L for 
      ethephon and thidiazuron, and 0-1 microg/L for diuron. The correlation 
      coefficients (r) were all over 0. 999. The limits of quantitation (LOQ) of 
      ethephon, diuron were 40 microg/kg, that of thidiazuron was 4 microg/kg. The 
      average recoveries varied from 89.4% to 100.2% with the relative standard 
      deviations (RSDs) of 5.7%-11.5% at three spiked levels (LOQ, 2LOQ and 4LOQ). The 
      method is simple, rapid and accurate, and can meet the requirements of the 
      domestic and international legislation. The method adapts to confirm the residues 
      of ethephon, thidiazuron and diuron pesticides in cotton samples.
