sci.beer-lambert-law Calculator
Calculates absorbance, transmittance, and analyte concentration using the Beer-Lambert law A = εcl. A solution with A = 1.0 transmits 10% of incident light — spectrophotometric assays use this to determine protein, DNA, or metabolite concentrations from absorbance readings.
Inputs
Molar Absorptivity
Reference formula or conversion factor shown for context.
Concentration Mol L
Amount of solute per unit volume. Higher concentration = more solute dissolved.
Path Length Cm
Linear measurement. Ensure consistent units: 1 m = 1,000 mm = 3.281 ft.
Results
absorbance A
Sample size or count used in the calculation.
transmittance T
Sample size or count used in the calculation.
% transmittance
Sample size or count used in the calculation.
A = εbc
Reference formula or conversion factor shown for context.
concentration check
A pass/fail verification against the applicable code, standard, or threshold.
linear range
The difference between the maximum and minimum values.
