Now do note this is from the perspective of organic chemistry. 1760, Pulfrich C (1925) Z Instrumentenkunde 45:116, 521, Löwe F (1949) Optische Messungen des Chemikers und des Mediziners. This is the most efficient tool for its compatibility and economic value in pharmaceutical analysis. to the primer "Fundamentals of Modern UV-visible Spectroscopy" (Hewlett-Packard publication number 12-5965-5123E) which can be used in teaching and learning the theory of UV-visible spectroscopy and instrumentation. Topics include formation of derivatives having absorbing chromophores; reactions leading to changes in absorption of added reagents; and analyses involving transformation to products suitable for spectrophotometry. It obeys Beer-Lambert law. Aufl. UV/VIS spectroscopy implies absorption/reflection measurements carried out in the ultraviolet and visible light spectrum. 2. Colorimetry can be used to assess the quality and purity of the finished product. Aufl. The wavelength of infrared light is longer than uv/vis. Among these are studies of environmental carcinogens, … Techn Fort- schrittsber, Bd 6. UV/Vis spectroscopy can be used in the manufacturing process to identify contaminants within a substance or measure the kinetics of a reaction. Applications of UV Visible Spectroscopy An analysis by the spectrophotometric methods attains accurate and fast results with small quantities of sample. The presence of impurities gives additional peaks other than λmax of the substance. UV/Vis spectroscopy is routinely used in analytical chemistry for the quantitative determination of different analytes, such as transition metal ions, highly conjugated organic compounds, and biological macromolecules. This correlation was then formulated mathematically by Lambert in 1760 [1] and Beer discovered the dependence upon the concentration in 1852 [2].

According to the Beer-Lambert law, which links the attenuation of light to the characteristics of the material through which the light passes, a sample’s absorbance is directly proportional to the concentration of the absorbing analyte.
