摘要：

A rapid, reliable method (60 samples/h) for the simultaneous determination of free and total sulfur dioxide (SO2) in wine has been developed employing a third-generation continuous flow analyzer, the TRAACS 800. Continuous flow analysis measured 75-100 % free SO2 compared to the Ripper method. Recoveries from sulfite-spiked wine samples ranged from 62 to 104 %, with an average precision of 4.5 %.
