Colorimetric testing is a method of determining the concentration of a chemical element or compound (organic or inorganic) in a solution with the aid of a colour reagent.

Our test kits measure the strength or weakness of a chemical presence according to the degree of colour saturation. Ie – if it is pale in colour, then the chemical concentration is low. If the colour is strong, then the chemical concentration is high. Simply add the reagent to the compound to be tested and match the colour gained against a colour chart included in the kit.

  • Phosphates are widely introduced into the environment from such sources as agricultural fertilisers, cleaning and laundering products, boiler water conditioners and drinking water treatment aids. At high levels, phosphates stimulate the growth of photosynthetic organisms which may contribute to eutrophication of lakes, rivers and ponds. This makes it important to monitor and control phosphate discharges into the environment.
