What is the Beer-Lambert Law Calculator & How does it work?
The Beer-Lambert Law is a fundamental principle in analytical chemistry that describes the relationship between the absorption of light by a solution and its concentration. It states that the absorbance (A) is directly proportional to the concentration (c) of the absorbing species and the path length (l) through which the light travels.This law is crucial for determining the concentration of a solution from its absorbance, or vice versa, using spectrophotometric techniques.
A = \epsilon \cdot c \cdot l
A = Absorbance
ε = Molar absorptivity
c = Concentration
l = Path length
ε = Molar absorptivity
c = Concentration
l = Path length
