General description

Method: colorimetric with color-disk comparator 0.1 - 0.3 - 0.5 - 0.7 - 1 - 2 - 3 - 4 - 5 mg/l S MQuant^®

The MQuant^® Sulfide test (formally MColortest^®) can be used for the determination of sulfides in e.g. •Groundwater and surface water•Drinking water and mineral water•Waters from aquaculture•Wastewater•Soils after appropriate sample pretreatmentThis test is not suited for seawater.MethodIn the acidic range, in which practically only dissolved hydrogen sulfide is present, this reacts with dimethyl-p-phenylenediamine and iron(III) ions to form methylene blue. The sulfide concentration is measured semiquantitatively by visual comparison of the color of the measurement solution with the color fields of a color disk. The test evaluates the color reaction based on the transmitted light method. So even turbid and colored water samples can be analyzed without further preparation. The color disk is made of very durable, lightfast plastic, thus suitable for industrial areas and wet environments. Using the refill pack 1.18468 containing all the reagents, the original test kit can be used for a very long time, making it a particularly economical and ecological system.
