Abstract

A rapid, reliable method (60 samples/h) for the simultaneous determination of free and total sulfur dioxide (SO 2 ) in wine has been developed employing a third-generation continuous flow analyzer, the TRAACS 800. Continuous flow analysis measured 75-100% free SO 2 compared to the Ripper method. Recoveries from sulfite-spiked wine samples ranged from 62 to 104%, with an average precision of 4.5%
