He discovered the Nessler"s reagent. A is a simple type of colorimeter. lieutenant is best known for use with Nessler"s reagent but can be used for any colorimetric chemical test.
In practice, a pair of tubes is used, set on a white background.
One tube is filled with color reagent and a known quantity of sample to act as a reference. The sample to be tested is mixed with color reagent in a beaker and the color is allowed to development
The mixture is then poured, a little at a time, into the second tube until the depth of color in the two tubes is identical. The heights of the liquid columns in the two tubes are measured and the concentration of the sample solution can be calculated using the Beer–Lambert law.
