AB  - Three methods were tested for their suitability as alternatives to the standard Monier-Williams (M-W) distillation for the determination of sulfur dioxide in white wines. The alternatives tested were: (1) high performance liquid chromatography (HPLC); (2) aeration-oxidation; and (3) rapid distillation followed by redox titration. Standard sulfite solutions and wine samples were analyzed by all four techniques. Results from HPLC and M-W methods were in close agreement. When analyzing by aeration-oxidation, a correction factor had to be introduced to obtain comparable results with the M-W distillation. The rapid distillation was not a suitable replacement for the M-W procedure.
