Apr 26 2021 Read 10 Times Laboratories rely on advanced instruments and techniques to carry out research, with UV Spectroscopy one of the most important methods. Used to measure the light absorbency rates of chemical substances, UV Spectroscopy is a quantitative technique used across a variety of different applications and industries, including microbiology, life sciences, pharmaceuticals and petrochemistry. The foundations of UV Spectroscopy UV Spectroscopy uses ultraviolet light to determine the absorbency of a substance. In simple terms, the technique maps the interaction between light and matter and measures. As matter absorbs light it undergoes either excitation or de-excitation, which generates what is known as a spectrum. This allows scientists to measure the rate at which a beam of light weakens after passing through a substance.
