More Details
Cobalt is an essential micronutrient for all multicellular organisms as the active center of cobalamin, such as vitamin B-12, which is essential for plants and animals. Cobalt is also a micronutrient for bacteria, algae, and fungi. Despite being an important micronutrient, excess cobalt in the environment can be deleterious to life leading to cardiomyopathy in humans and necrosis in plants.Simple, direct, and automation-ready procedures for measuring cobalt concentrations find wide applications in research and environmental monitoring. BioAssay Systems’ cobalt assay kit is designed to measure total cobalt directly in aqueous samples without any pretreatment. The intensity of the color, measured at 485nm, is directly proportional to the cobalt concentration in the sample.Do other ions interfere with the detection of Cobalt ions?
The metal ions Fe2+, Cu2+, Zn2+, Mn2+, Mg2+, Al3+, Mo2+, Pb2+ and W2+ exhibit less than 10% interference in this assay. Ni2+ concentrations >10% of Co2+ concentration should be avoided. Excessive Ca2+ may cause precipitation to occur.
Will increasing the incubation time with the Detection Reagent increase the sensitivity of the assay?
No, increasing the incubation time beyond about 15-20 minutes will only result in the formation of a precipitate. The color formation with Cobalt ion is almost instantaneous, so a longer incubation time is not required.
