General description
The MQuant® Color test (formally MColortest®) is used for the visual comparison of yellow tinted waters with simulated platinum-cobalt standards according to Hazen.
Method
The color of the liquid under investigation is measured semiquantitatively by visual comparison of the measurement solution with the color fields of a color card. The result obtained when measuring an unfiltered sample corresponds to the “apparent color”, which is caused by dissolved substances and suspended matter. When the sample is filtered prior to the measurement, the result corresponds to the “true color”, which is caused only by dissolved substances. The two results are identical in the case of clear samples. The color of water samples depends strongly on the pH. When measuring the color, it is hence advisable to also determine the pH of the water sample under investigation (e.g. with MQuant® pH indicator strips). The unique brilliance of the print and their fine color graduation allow precise analyses.
This test is suitable for testing the color in
