Free and total SO2 in Beverages

This application is used for the free and total sulfur dioxide (SO2) content determination in beverages. The titration is monitored by voltametric measurement with a current-polarized double Platinum pin sensor. The titration is terminated at a predefined potential.

Sulphur dioxide in wine is found in three different forms SO₂, bisulphite HSO₃^- ion and sulphite SO₃^2- ion. The total content of all these forms can be determined in wine using the given technique using Easy autotitrator.
