Product Information

Phosphorus occurs naturally in rock formations in the Earth's crust, usually in the form of phosphate.
Using the colorimetric method, this kit employs the molybdovanadic acid method. Phosphate reacts with ammonium molybdate under acid conditions and in the presence of vanadium to form a yellow product.

An ampoule is immersed in the sample and the tip is snapped off. The correct volume of sample is drawn in and a small inert gas bubble forms. Sample and reagent are mixed by tilting the ampoule so the bubble travels from end to end. In two minutes or less, the resulting color is compared to the appropriate color standards (comparators or color chart) to quantify the result.

The intensity of the color formed is directly proportional to the phosphate concentration in the sample. Approx. analysis time four minutes. Range 0–250 ppm. 0–12 and 25–250 ppm.
