Method

The analyser, with the SO2 electrode and reagents provided, can be used to determine sulfite (or SO2) levels in wine, musts, and other samples. It relies on the Ripper titration based on the quantitative reaction of the SO2 with iodine (generated during the titration) which oxidises the SO2 in the sample under acid conditions.

When all the SO2 is titrated at the end point, excess iodine appears in solution. This is detected as current with the SO2 electrode and signalled by audible and visual indicators. The endpoint is much more sensitive than the starch colour change commonly employed for Ripper titration, and it is sharp and clear, even when titrating red wines and musts. From the known concentration of the titrant and its volume required to reach the end point, the free SO2 is simply calculated.
