Beer—Lambert law can be applied to the analysis of a mixture by spectrophotometrywithout the need for extensive pre-processing of the sample.

Pierre Bouguer – Wikipedia

The reason is that the attenuation coefficient also depends on concentration and density, even in the absence of any interactions. His name is also recalled as the meteorological term Bouguer’s halo also known as Ulloa’s haloafter Antonio de Ulloaa Spanish member bouuguer-beer his South American expedition which an observer may see infrequently in fog when sun breaks through for example, on a mountain and looks down-sun—effectively a bougyer-beer Fog bow ” as opposed to a “rain-bow”.

An Introduction to Meteorological Optics, pages — He also invented a heliometerafterwards perfected by Joseph von Fraunhofer.

From Wikipedia, the free encyclopedia. Scattering, absorption and radiative transfer optics Spectroscopy Electromagnetic radiation Visibility.

In January he was elected a Fellow of the Royal Society. The law is commonly applied to chemical analysis measurements and used in understanding attenuation in physical opticsfor photonsneutrons or rarefied gases. In mathematical physicsthis law arises as a solution of the BGK equation. In other projects Wikimedia Commons. For a more complicated example, consider a mixture in solution containing two species at amount concentrations c 1 and c 2.

When working in concentration units of molarity, the Beer-Lambert law is written as:. The Beer—Lambert legalso known as Beer’s lawbouguer-bewr Lambert—Beer lawor the Beer—Lambert—Bouguer law relates bouguer-beed attenuation of light to the properties of the material through which the light is travelling. His later writings were nearly all upon the theory of navigation and naval architecture.


In Bouguer sailed with Charles Marie de La Condamine on a scientific mission to Perulley measure a degree of the meridian arc near the equator.

In he was made professor of hydrography at Havreand succeeded Pierre Louis Maupertuis as associate geometer of the Academy of Sciences. The law tends to break down at very high concentrations, especially if the material is highly scattering. He was afterwards promoted in the Academy to the place of Maupertuis, and went to reside in Paris. By using this site, you agree to the Terms of Use and Privacy Policy. It can be made compatible with Maxwell’s equations if the transmittance of a sample with solute is ratioed against the transmittance of the pure solvent which explains why it works so well in spectrophotometry.

In case of uniform attenuation, these relations become [5].

The law was discovered by Pierre Bouguer before Views Read Edit View history. A large bronze statue of him stands at the port in Le Croisic. The main reason, bbouguer-beer, is the following. Ten years were spent in this operation, a full account of which was published by Bougufr-beer inLa figure de la terre. The law is used widely in infra-red spectroscopy and near-infrared spectroscopy for analysis of polymer degradation and oxidation also in biological tissue as well as to measure the concentration of various compounds in different food samples.


This law is also applied bouuguer-beer describe the attenuation of solar or stellar radiation as it travels through the atmosphere. Experimental measurements are usually made in terms of transmittance Twhich is defined as:. This two system equation can be solved using Cramer’s rule.
