A REVIEW ON UV-VISIBLE SPECTROSCOPY

Ultraviolet spectroscopy is a oldest instrument-based analytical technique, has shown crucial tool in numerous scientific areas. Beer's law, an important idea in UV spectroscopy, describes how samples absorb light. Both quantitative and qualitative analyses can be conducted effectively using UV spectroscopy. It gives precision in their result and used for the analysis of variety of sample compounds. It determines the Electromagnetic Radiation which is absorbed when molecules or atoms and ions of the sample move from one energy state to another energy state. The monochromator is used to convert the chromatic light into single desirable monochromatic light. Converts the light into electrical signal, and the detector convert the polychromatic light into electrical signal.
