The K-9610W Sulfite Kit was designed to accurately measure the levels of Sulfite from 10-100 ppm. K-9610W uses the Ripper MethodCHEMetrics' sulfite test kit is based on the Ripper method, which the wine industry has used for years as a standard for rapid sulfite analysis. Sulfite is titrated with an iodide-iodate solution, using a starch end point indicator. Phosphoric acid is used to adjust the pH of the sample. Results are quantified using direct-reading titration cells. The test determines free sulfite as ppm (mg/L) SO2.

Results for this test kit are acceptable for white wines (although they can have an error of up to 10 ppm).  *This test kit is not recommended for use with red wines or white wines containing ascorbic acid or tanninThese wines often give false high test results.
