Colorimetry is the science of measuring color, replacing subjective responses of colors with an objective numerical system. It is used to quantify and describe physically the human color perception. Colorimetry is similar to spectrophotometry, but it is distinguished by its interest in reducing. The key features of colorimetry include:
-
Measurement of color: Colorimetry is the field in which a colored compounds concentration in a solution is measured.
-
Colorimeter: A colorimeter is a device used in colorimetry that helps specific solutions to absorb a particular wavelength of light. It is an analytical system that calculates the absorption of a certain wavelength of light as a method to calculate a solution concentration.
-
Beer-Lambert law: The colorimeter is usually used to measure the concentration of a known solute in a given solution with the help of the Beer-Lambert law. The law states that when a beam of incident light of intensity Io passes through a solution, a part of it is reflected, and a part of it is absorbed.
Colorimetry is used extensively for identification and determination of concentrations of substances that absorb light. It is a very quick and efficient way of analyzing colored solutions or any colored substance. The immense potential of colorimetry in terms of applications ranging from food, textiles, and more.
