General description

The MQuant^® Phosphate test (formally MColortest^®) can be used for the determination of orthophosphate in: Groundwater and surface water, seawater Drinking water and mineral water Waters from aquaculture Industrial water Boiler water Process water Wastewater Electroplating wastewater Nutrient solutions for fertilization Soils after appropriate sample pretreatmentMethodIn sulfuric solution orthophosphate ions react with ammonium vanadate and ammonium heptamolybdate to form orange-yellow molybdovanadophosphoric acid. The phosphate concentration is measured semiquantitatively by visual comparison of the color of the measurement solution with the color fields of a color disk. 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. Using the refill pack 1.18466 containing all the reagents, the original test kit can be used for a very long time, making it a particularly economical and ecological system.

Method: colorimetric, VM, with color-disk comparator 1.5 - 3 - 6 - 9 - 12 - 16 - 20 - 40 - 100 mg/l PO₄-P MQuant^®
