Absorbance and colorimetric assays are designed to detect or quantitate the amount of a particular reagent in an assay by measuring the amount of light absorbed by the reagent or chromogenic reaction product at a characteristic wavelength. This wavelength is specific to the reagent being measured.

Is the colorimetric method of analysis?

Colorimetric analysis is a method of determining the concentration of a chemical element or chemical compound in a solution with the aid of a color reagent. It is applicable to both organic compounds and inorganic compounds and may be used with or without an enzymatic stage.

What is colorimetric analysis used for?

Colorimetric analysis is the technique normally used to determine the concentration of analyte through comparing the color changes of the solution.
