Beer-Lambert Law

Calculate absorbance and transmittance from concentration using the Beer-Lambert law.

Molar Absorptivity ε (L/mol·cm)

Path Length (cm)

Concentration (mol/L)

À propos de cette calculatrice

The Beer-Lambert law A = ε·l·c links absorbance to the molar absorptivity, path length and concentration. Transmittance is 10^(−A).
