A rapid, simple, reliable and accurate method for the measurement and analysis of total sulfite (sulphite) and free sulfite in wine, beverages, foodstuffs and other materials. Supplied as a “ready to use” liquid stable formulation that is suitable for manual, auto-analyser and microplate formats.

Suitable for manual, auto-analyser and microplate formats.

Colourimetric methods for the determination of Total and Free
Sulfite in wine, fruit juice, foodstuffs and other materials

Principle:
The Total Sulfite assay is based on the reaction principle
between thiol groups and Ellman’s reagent

The Free Sulfite assay is based on the reaction principle of
SO₂, fuchsin and aldehyde binding
