Web4 jan. 2024 · The Beer-Lambert Law states: The absorbance of a solution is directly proportional to the path length of the sample and concentration of the attenuation species in the solution. ( Note: Attenuation is the scientific term for the gradual loss in flow intensity when passing through a medium.) WebBoth of these rely on the Beer-Lambert rule, which stipulates that a sample's absorbance is inversely related to its concentration and the length of the light's journey through it. The two approaches do differ in a few ways, though. In single-cuvette spectrophotometry, the absorbance of a single sample is determined in a cuvette.
