Beer’s Law Calibration Curve Generator

Scientific Background

Beer’s Law relates absorbance (A) to the concentration (c) of an analyte in solution:

Formula: A = ε × l × c

• A (Absorbance): Unitless measure of light absorption
• ε (Molar Absorptivity): L/(mol·cm)
• l (Path Length): cm
• c (Concentration): mol/L

This application generates a calibration curve by calculating absorbance values at sample concentrations using Beer’s Law.
