Applications of Beer-Lambert’s Law
1. Beer's law is important in the field of physics, chemistry and meteorology.
2. The law is used in chemistry to measure the concentration of chemical
solutions.
3. To determine the molar absorptivity of a substance.
4. To analyze oxidation.
5. For quantification and identification of matter by spectrophotometry.
6. It is used widely in infrared spectroscopy for analyzing polymer degradation.
7. Estimating the stoichiometric coefficients.
8. Beer’s law also applies to a medium containing more than one kind of absorbing
substance.
9. Provided there is no interaction among the various species, the total absorbance
for a multi-component system is given by this law.
10. It is applied to the analysis of a mixture by spectrophotometry, without the
need for extensive pre-processing of the sample.
11. The law also explains the attenuation of radiation through the Earth's
atmosphere.
