WebThe relationship between absorbance and concentration is known as Beer's law (also referred to by other names such as the Beer–Lambert law and the Bouguer–Lambert–Beer law) and is defined by the equation: where A is the absorbance of the solution (no units), ε is the molar absorptivity (units of l mol −1 cm −1 ), b is the path length ... WebThe simulation here includes only the two most common instrumental deviations from Beer's Law: polychromaticity and unabsorbed stray light errors.The simulation operates like any numerical integration, by slicing up the spectral range viewed by the detector into a large number of small slices and assuming that the Beer-Lambert Law applies over each …
