Merck, 1.14406, Manganese Test

General description
Method: colorimetric with color card and comparator block with long test tubes 0.03-0.06-0.10-0.15-0.20-0.25-0.3-0.4-0.5 mg/l Mn MQuant®
The MQuant® Manganese test (formally MColortest®) measures bivalent manganese in its dissolved form.
It can be used for e.g.
Groundwater and surface water, seawater
Drinking water and mineral water
Spring water and well water
Boiler and boiler feed water, cooling water
Wastewater
Electroplating wastewater
Nutrient solutions for fertilization
Soils after appropriate sample pretreatment

Method
In alkaline solution manganese(II) ions react with an oxime to form a red-brown complex. The manganese 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.
Due to the long test tubes a sensitive measurement range can be covered.
Using the refill pack 1.18460 containing all the reagents, the original test kit can be used for a very long time, making it a particularly economical and ecological system.
The test measures bivalent manganese in its dissolved form. The manganese concentration can be measured semiquantitatively by visual comparison of the colour of the measurement solution with the colour fields of the color disk.
