SEOH Analytical Test Strips for Determination of Sulphites and Sulphur Dioxide

This test paper is recommended for the rapid detection of sulphites and gaseous sulphur dioxide. The white paper turns pink to brick-red in the presence of sulphite or free sulphur dioxide. The paper does not react with sulphites in acidic solutions. These have to be neutralized with solid sodium acetate. Thio-sulphates only interfere with the determination of gaseous sulphur dioxide.Limit of sensitivity: 10 mg/l Na 2 SO 3Note: sulphite test paper can also be used for medical-diagnostic purposes as a rapid test for sulphite oxidase deficiency.
