Descripción general
Method: colorimetric with color-matching vessel 0.1 - 0.3 - 0.5 - 1.0 - 2.5 - 5.0 - 7.5 - 12.5 - 25 - 50 mg/l Fe MQuant®
The MQuant® Iron test (formally MColortest®) measures bivalent and trivalent iron in its dissolved form and also fresh colloidal e.g. in
We also recommend this as a pretest for the oxygen determination with MQuant® Oxygen 1.11107 to check for iron interferences in the sample.
This 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 matching vessel 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 by hydroxylammonium chloride. In a buffered medium these react with 2,2′-bipyridine to form a red complex. The iron concentration is measured semiquantitatively by visual comparison of the color of the measurement solution with the color zones of a color matching vessel.
Without the addition of hydroxylammonium chloride (reagent Fe-1), the test measures only iron(II). so a differentialtion is possible.
Using the refill pack 1.08023 containing all the reagents, the original test kit can be used for a very long time, making this a particularly economical and ecological system.
- Groundwater and surface water
- Waters from aquaculture
- Drinking water and mineral water
- Industrial water
- Wastewater and percolating water
- Boiler and boiler feed water, cooling water
- Food (e. g. wine) after appropriate sample pretreatment

The test measures bivalent and trivalent iron in its dissolved form and also fresh colloidal iron(III)hydroxide in e.g. groundwater and surface water, drinking water, industrial water and wastewater, whereas a differentiation between iron(II) and iron(III) is possible.
