In beer-lambert law what is the path length
WebIn AA spectroscopy - the length of the flame acts as the fixed path length and in UV-Vis spectroscopy, the diameter of the cuvette, or sample container, acts as the fixed path length. It is important to note that there are several reasons why Beer's Law may not be valid for a particular experimental system. WebThe Beer-Lambert Law. The Beer-Lambert Law (also called Beer’s Law) is a relationship between the attenuation of light through a substance and the properties of that substance. In this article, the definitions of transmittance and absorbance of light by a substance are first introduced followed by an explanation of the Beer-Lambert Law.
