TI  - Comparison of methods for extraction of ethyl carbamate from alcoholic beverages 
      in gas chromatography/mass spectrometry analysis.
PG  - 1048-51
AB  - A procedure to analyze ethyl carbamate (EC) by gas chromatography/mass 
      spectrometry was optimized and validated. Deuterated EC (d5-EC) was added to the 
      samples as an internal standard followed by extraction with polystyrene 
      crosslinked polystyrene cartridges using minimal volumes of ethyl acetate. The EC 
      response was measured in selective ion monitoring (SIM) mode and found to be 
      linear in the range between the limit of quantitation (10 micro/L) and 1000 
      microg/L. EC recoveries varied from 92 to 112%, with the average value of 100 +/- 
      8%. The procedure compared well (r2 = 0.9970) with the existing AOAC Official 
      Method with the added benefits of minimal solvent usage and reduced matrix 
      interferences.
