The development of automated analysis of sulphur dioxide has proven a major breakthrough in wine analysis. With the WineScan SO2 solution it is now possible to accurately analyse free and total sulphur dioxide in parallel with other parameters in just over two minutes. Turnaround time for results is dramatically improved and workload and risk of human error is reduced.
Using innovative technology, the WineScan SO2 provides robust and documented performance. In addition to routine analysis of sulphur dioxide, an increasing number of wine laboratories around the world have achieved accreditation of the use of the instrument as part of their laboratory services. The instrument uses Fourier transform infrared (FTIR) for testing parameters such as Ethanol, pH, sugars, organic acids and many more. For SO2 analysis, phosphoric acid is used as a hydrolysing agent to release SO2 gas from the wine sample, that is subsequently scanned using FTIR.
How it works
Time-to-result compares favourably with around 15 minutes per test with existing routine methods or longer for laboratory reference methods. The system is also considerably more convenient, reducing manual work and associated risks of operator error. Results are delivered alongside the many other quality parameters provided by the WineScan analyser. This gives you a convenient on-screen comparison against parameters, such as pH and ethanol, of potential interest in combination with sulphur dioxide.
WineScan SO2 has been approved as a method for the official final analysis of wines in Germany. Further to this approval, positive results from a ring test by top German wine laboratories and a similar study by FOSS gives yet more indication of the reliability of the WineScan against standard methods. One main difference remains though. The WineScan is much faster.
