Why is it necessary to dilute the concentration in a UV spectrometer

Home / Why is it necessary to dilute the concentration in a UV spectrometer

By carefully diluting solutions and using spectrophotometric analysis, scientists can precisely determine concentrations. Why is serial dilution an important technique in laboratory science? If you begin with a 0. Prior to use, it's crucial to verify that Beer's Law applies to the species within the concentration range under investigation, as deviations can arise at higher concentrations. UV-Vis spectroscopy measures how much ultraviolet (UV) or visible light a sample absorbs.
