The quantity of radiation absorbed is given by the Lambert-Beer Law: log Io/I = ελ c d Where log Io/I = Absorbance (A) ελ = molar extinction coefficient of the substance at wavelength λ c = molar concentration of the substance d = optical distance light travels through sample Therefore, the concentration "c" can be calculated from the color intensity of the substance determined by the emitted radiation I, as the other factors are known.
