What is the importance of absorbance?
In biology and chemistry, the principle of absorbance is used to quantify absorbing molecules in solution. Many biomolecules are absorbing at specific wavelengths themselves.
What is the definition of absorbance?
What is absorbance? Absorbance is related to the number of photons a sample absorbs. When an atom or molecule absorbs a single photon, an electron makes a transition to a higher orbital energy. As the number of atoms or molecules increases more photons can be absorbed.
What is the relationship between absorbance and concentration?
Absorption means that a substance captures and transforms energy while concentration refers to the amount of a substance in a defined space. If the concentration of solution is increased, then there are more molecules for the light to hit when it passes through.
How do you measure absorbance?
Absorbance is measured using a spectrophotometer or microplate reader, which is an instrument that shines light of a specified wavelength through a sample and measures the amount of light that the sample absorbs.
