Abstract (en)
[origin: WO02095392A2] The invention relates to a method and test kit for detecting, in particular, free sulfite in aqueous samples. The sample is introduced into a closeable receptacle, is preferably rendered slightly acidic with acid, and a test strip is used to determine the sulfite content in the gas phase above the sample. The analysis can ensue visually or reflectometrically. The inventive test kit for carrying out the method comprises a closeable receptacle and a test strip for analyzing sulfite.
