Lambert-beer's law
TīmeklisThe Beer-Lambert law is known by so many names because more than one law is involved. In 1729, Pierre Bouguer discovered the law. Later, in 1760, Johann Heinrich Lambert quoted Bouger’s discovery saying that the absorbance of a sample is directly proportional to the path length of light. TīmeklisBeer–Lambert law.

TīmeklisLimitations to Beer's Law. Beer’s law suggests that a plot of absorbance vs. concentration—we will call this a Beer’s law plot—is a straight line with a y-intercept of zero and a slope of ab or \(\varepsilon b\).In some cases a Beer’s law plot deviates from this ideal behavior (see Figure \(\PageIndex{9}\)), and such deviations from linearity … Tīmeklis2024. gada 12. febr. · The length \(l\) is used for Beer-Lambert Law described below.
