The Beer–Lambert law, also known as Beer's law, the Lambert–Beer law, or the Beer–Lambert–Bouguer law relates the attenuation of light to the properties of the material through which the light is travelling. The law is commonly applied to chemical analysis measurements and used in understanding … Skatīt vairāk The law was discovered by Pierre Bouguer before 1729, while looking at red wine, during a brief vacation in Alentejo, Portugal. It is often attributed to Johann Heinrich Lambert, who cited Bouguer's Essai d'optique sur la … Skatīt vairāk A common and practical expression of the Beer–Lambert law relates the optical attenuation of a physical material containing a single attenuating species of uniform concentration to the optical path length through the sample and absorptivity of the species. … Skatīt vairāk This law is also applied to describe the attenuation of solar or stellar radiation as it travels through the atmosphere. In this case, there is scattering of radiation as well as absorption. The optical depth for a slant path is τ′ = mτ, where τ refers to a vertical path, m … Skatīt vairāk • Beer–Lambert Law Calculator • Beer–Lambert Law Simpler Explanation Skatīt vairāk Under certain conditions the Beer–Lambert law fails to maintain a linear relationship between attenuation and concentration of Skatīt vairāk The 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. The spectrum of pure bilirubin is … Skatīt vairāk • Applied spectroscopy • Atomic absorption spectroscopy • Absorption spectroscopy • Cavity ring-down spectroscopy Skatīt vairāk
