TI  - Ultrasound-assisted emulsification microextraction for determination of 
      2,4,6-trichloroanisole in wine samples by gas chromatography tandem mass 
      spectrometry.

AB  - A fast and effective microextraction technique is proposed for preconcentration 
      of 2,4,6-trichloroanisole (2,4,6-TCA) from wine samples prior gas chromatography 
      tandem mass spectrometric (GC-MS/MS) analysis. The proposed technique is based on 
      ultrasonication (US) for favoring the emulsification phenomenon during the 
      extraction stage. Several variables influencing the relative response of the 
      target analyte were studied and optimized. Under optimal experimental conditions, 
      2,4,6-TCA was quantitatively extracted achieving enhancement factors (EF) > or = 
      400 and limits of detection (LODs) 0.6-0.7 ng L(-1) with relative standard 
      deviations (RSDs) < or = 11.3%, when 10 ng L(-1) 2,4,6-TCA standard-wine sample 
      blend was analyzed. The calibration graphs for white and red wine were linear 
      within the range of 5-1000 ng L(-1), and estimation coefficients (r(2)) were > or 
      = 0.9995. Validation of the methodology was carried out by standard addition 
      method at two concentrations (10 and 50 ng L(-1)) achieving recoveries >80% 
      indicating satisfactory robustness of the method. The methodology was 
      successfully applied for determination of 2,4,6-TCA in different wine samples.
