General description

Method: colorimetric with color card and comparator block with short test tubes 0.10 - 0.20 - 0.30 - 0.45 - 0.6 - 0.8 - 1.0 - 1.3 - 1.6 mg/l Cr 0.22 - 0.45 - 0.67 - 1.0 - 1.3 - 1.8 - 2.2 - 2.9 - 3.6 mg/l CrO MQuant^®

The MQuant^® Chromate test (formally MColortest^®) measures chromium(VI) present in the sample as chromate or dichromate ions in wastewater and percolating water, groundwater and surface water, industrial water and drinking water. MethodIn weakly phosphoric solution chromium(VI) ions react with diphenylcarbazide to form chromium(III) and diphenylcarbazone, which form a red-violet complex. The chromate concentration is measured semiquantitatively by visual comparison of the color of the measurement solution with the color fields of a color card. The unique brilliance of the print and their fine color graduation allow precise analyses, even at the lower end of the concentration range. Using the refill pack 1.18456 containing all the reagents, the original test kit can be used for a very long time, making it a particularly economical and ecological system.
