Is any difference between absorption and Absorbance in spectrophotometry?
I have found on net,that Mr.Beer found out independence between absorption and concentration of absorbent particles.And I don t understand that,because Beer-Lambert law says,that Absorbance IS dependent on concentration,isn it?
