What Does AU Stand For?
AU stands for Absorbance Units
AU, or Absorbance Units, is a unit of measurement used in spectrophotometry to quantify the absorbance of a substance at a specific wavelength of light. It reflects the amount of light absorbed by a sample, providing insights into the concentration and properties of the analyte. The value is logarithmic, calculated as the logarithm of the ratio of incident light intensity to transmitted light intensity, facilitating comparisons across different samples and conditions.
