What is a spectrophotometer?
A UV/Vis spectrophotometer is an analytical instrument used to measure the absorbance of ultraviolet and visible light by a sample, providing insights into its molecular composition and concentration. It operates over a wavelength range typically from 190 nm to 1100 nm, encompassing both the ultraviolet (UV) and visible (Vis) regions of the electromagnetic spectrum. This range allows for the analysis of a wide variety of substances (organic, inorganic substances, Biological samples, pharmaceuticals), making it a versatile tool in chemical and biological research.
