Merck, 1146700001, Chlorine Test in freshwater and seawater

MQuant® Chlorine Test is a visual colorimetric kit for determining chlorine concentrations in freshwater and seawater. Its measurement scale covers 0.10–2.0 mg/L expressed as Cl₂, supporting routine checks of aquatic systems and water-treatment performance. The test can be applied in monitoring programs where a compact wet-chemical method is preferred over an electronic photometer. Operators develop a color reaction in the prepared sample and compare the result with the appropriate reference scale. The 1146700001 configuration contains reagents for 100 tests and is specified for storage at 15–25°C. Applications include aquaculture-related water checks, drinking-water investigations, and environmental water analysis where the measurement range and sample composition are appropriate. The result should be reported as chlorine equivalent in mg/L Cl₂.
