Kolorimetern

Kolorimetern is an analytical technique used to measure the concentration of a substance in a solution by analyzing the amount of light absorbed or transmitted by the solution. The principle behind kolorimetern is based on the Beer-Lambert Law, which states that the absorbance of light by a solution is directly proportional to the concentration of the absorbing species and the path length of the light through the solution.

In kolorimetern, a sample solution is placed in a cuvette, a small transparent container, and exposed to light of a specific wavelength. The light that passes through the solution is measured by a detector, and the amount of light absorbed is compared to a reference solution. The difference in absorbance between the sample and the reference is used to calculate the concentration of the substance in the sample.

Kolorimetern is widely used in various fields, including chemistry, biology, and environmental science, for quantitative analysis of substances such as proteins, enzymes, and pollutants. It is a simple, rapid, and cost-effective method for determining the concentration of a substance in a solution. However, it requires careful selection of the wavelength of light and the reference solution to obtain accurate and reliable results.
