Molar absorbance of one component in a mixture (Beer-Lambert law)

Formula

Molar absorbance of one component in a mixture (Beer-Lambert law) formula
epsilon2
molar absorbance of one component in the mixture
c2
the corresponding concentration of this component
c1
concentration of another component in the mixture
epsilon1
the corresponding molar absorbance of this component
A
The total absorbance at wavelength lambda

Formula description

Beer-Lambert law can be applied to the analysis of a mixture by spectrophotometry, without the need for extensive pre-processing of the sample. An example is the determination of bilirubin in blood plasma samples.
