Kvasny Prum., 38(4): 106-108. (in Czech, English abstract). The whole content of sulphur dioxide was determined by the method of flow injection analysis (FIA) using malachite green. In the sample preparation the distillation procedure using Kjeltec 1002 Tecator (the distillation time is 3 min) and the extraction with tetrachloromercuric agent (TCM) were tested. The FIA method is rapid and reliable. The analyseis lasts 90 s without a sample preparation. Sorbic acid was determined by a rapid and simple HPLC method.
