WebOct 13, 2024 · Introduction. The Beer-Lambert law [] relates the molar concentration (C) of a solute to absorbance of light according to the equation C = ϵA where ϵ is the molar extinction coefficient and A is the absorbance.Epsilon (ϵ) is given at a specific wavelength and specific light path, usually a 1 cm light path. That relationship is what allows us to monitor enzyme …
