WebMar 17, 2014 · You will be applying Beer's law to calculate the concentration. The equation for Beer's law is: A = εmCl. (A=absorbance, εm = molar extinction coefficient, C = concentration, l=path length of 1 … WebThis method is used mostly for a very rough estimation of concentration, e.g. to check the success of purification. A = ɛ cl. A is the absorbance (e.g. A 280) ɛ is the molar extinction coefficient, M-1 cm-1 – this can be found from the literature; c is concentration in M; l is the path length in cm – the length of the cuvette / microplate
