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.

The portable spectrophotometry can be used for analyzing the concentration of the primary colors in the solution that contribute to its overall appearance. Wave length the wavelength of light absorption or transmittance is measured based on the wavelength in nanometers. The true unit of measurement of absorbance is reported as absorbance units. or au.
Differentiating compounds is another uses of spectrophotometer.it works by analyzing the pattern of wavelengths absorbed by the sample. Red dye #3 with a concentration of 5.88 μm has an absorbance of 0.468 in the lab spectrophotometer.
