What is UV-VIS spectrometry?

UV-VIS spectrophotometry is based on the principle that molecules absorb light at specific wavelengths, and this absorption is proportional to the concentration of the absorbing substance in the sample. The key equation governing this relationship is known as the Lambert-Beer Law, also referred to as Beer's Law or the Beer-Lambert Law. It describes the linear relationship between the absorption of light by a substance and its concentration in a solution.

The Beer-Lambert Law

The law is expressed mathematically as: A=ε⋅c⋅l

  • A is the absorbance of the sample.
  • ε (epsilon) is the molar absorptivity or molar extinction coefficient.
  • c is the concentration of the absorbing species in the solution.
  • l is the path length of the cuvette, i.e., the distance that light travels through the sample.
