The Total Sulfite (Enzymatic) test kit is a simple, highly specific and reliable, enzymatic method for the measurement and analysis of total sulfite (as SO2) in wines, beverages, foodstuffs and other materials.
Extended cofactors stability. Dissolved cofactors stable for > 1 year at 4oC.
Suitable for manual, auto-analyser and microplate formats.
UV-method for the determination of Total Sulfite (SO22-) in
beverages,foodstuffs and other materials
Principle:
(sulfite oxidase)
(1) SO32- + O2 + H2O ? SO42- + H2O2
(NADH - peroxidase)
(2) H2O2 + NADH + H+ → 2 H2O + NAD+
