About Extinction Coefficient Calculator (Formula)

The Extinction Coefficient Calculator is a tool that allows to calculate the extinction coefficient of a substance. The Extinction coefficient is a measure of how much a substance absorbs light at a specific wavelength. It is a fundamental parameter in spectrophotometry, a widely used analytical technique for determining the concentration of a substance in a solution.

The formula used to calculate the extinction coefficient is: E = A / mc Where:

  • E is the extinction coefficient
  • A is the absorbance of the substance, measured at a specific wavelength
  • mc is the molar concentration of the substance.

Knowing the extinction coefficient of a substance is important in many fields such as biochemistry, analytical chemistry, and environmental monitoring.

The Extinction Coefficient Calculator can be used to calculate the extinction coefficient based on the given absorbance and molar concentration, this is useful for scientists and researchers to determine the concentration of a substance in a solution or study the properties of a substance in a solution.
