AB  - A rapid, selective and effective method of extraction, clean-up and concentration 
      of organophosphorous pesticides from wheat followed by electrospray (ESI) 
      LC-MS/MS analysis was developed. The mu-SPE (micro-solid-phase extraction) 
      procedure resulted in good analytical performance and reduced at the same time 
      matrix effects, analysis time and solvent consumption. Limits of detection (LODs) 
      and quantification (LOQs) were in the range of 0.3-10 and 1-30 mug kg(-1), 
      respectively, with good reproducibility (RSD </= 13.8) and recoveries between 75% 
      and 109%. Coefficients of determination (r(2)) were greater than 0.996 for the 
      studied pesticides. Despite the reduced sorbent bed mass of mu-SPE tips (4.2 mg), 
      the analytical data showed that no saturation phenomena occurs in the tested 
      range of concentration both for single compounds and mixtures. Several real 
      samples were analysed and the concentrations of the selected pesticides were 
      found to be below the respective maximum residue limit (MRLs).
