General Description

Method: colorimetric with color-disk comparator 0.1-0.2-0.3-0.5-0.8-1.2-2-3-5 mg/l Fe MQuant^®The MQuant^®Iron test (formally MColortest^®) measures bivalent and trivalent iron in its dissolved form as well as fresh colloidal iron(III) hydroxide in

• Groundwater and surface water, seawater
• Drinking water and mineral water
• Waters from aquaculture
• Boiler and boiler feed water, cooling water
• Industrial water
• Wastewater and percolating water

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.

Method
All iron ions are reduced to iron(II) ions. In a thioglycolate-buffered medium these react with a triazine derivative to form a red-violet complex. The iron concentration is measured semiquantitatively by visual comparison of the color of the measurement solution with the color fields of a color disk.

Using the refill pack 1.18458 containing all the reagents, the original test kit can be used for a very long time, making it a particularly economical and ecological system.
