How This Works
\n
Beer’s Law states that the absorbance of a solution is directly proportional to the concentration of the absorbing species and the path length of the light through the solution. The formula is:
\n
A = εbc
\n
Where:
\n
- \n
- A is the absorbance (unitless)
- ε is the molar absorptivity (L mol⁻¹ cm⁻¹)
- b is the path length (cm)
- c is the concentration (mol L⁻¹)
