…measurements would deviate from the Beer–Lambert law. The above factors contribute to the measurement uncertainty of the results obtained with UV–Vis spectrophotometry. If UV–Vis spectrophotometry is used in quantitative chemical analysis then the results are additionally affected by uncertainty sources arising from…
