Merck, 1111480001, Sulfite Test

Sulfite Test is designed for titrimetric determination of sulfite in water samples using an MQuant® iodometric workflow. The test determines the sulfite concentration through a chemical titration rather than membrane filtration, visual test strips or photometric measurement. It is suited to wastewater, boiler water and water circulating in heating systems, where sulfite measurement forms part of water chemistry monitoring. The titration is performed with the corresponding MQuant® titration pipette system, enabling sulfite concentration to be obtained from the delivered titrant volume. This product contains sufficient materials for 200 tests and is supplied in a plastic box. Store the kit at 15–25 °C. Because the determination is specifically titrimetric, it is appropriate for laboratories and operators that use a manual iodometric method rather than instruments requiring a calibrated light detector. The package format supports repeat monitoring of sulfite in utility and process-water streams with the same reagent system. This is a sulfite assay; it should not be confused with tests measuring sulfate or other sulfur species.
