Resumo(s)
A method for analysis of heavy sulphur compounds in wines, based on gas chromatography (GC) with flame photometric detection, is
reported. Wine samples preparation includes a dichloromethane liquid–liquid extraction followed by concentration under a nitrogen atmosphere.
The extracted fraction was also analysed by GC–mass spectrometry. The method enables high recovery of sulphur compounds in wine
and satisfies the requirements of repeatability and sensitivity. Applications of the method to red, white and Port wines are reported.
