# What Units Are Used To Measure Absorbance On A Spectrophotometer

What Units Are Used To Measure Absorbance On A Spectrophotometer. They can help identify compounds. determine concentrations of solutions. or estimate the number of cells suspended. Absorbance is measured using a spectrophotometer. which is a tool that shines white light through a substance dissolved in a solvent and measures the amount of light that the substance absorbs at a specified wavelength.
