Ultraviolet-Visible spectroscopy (UV/VIS) is a specialized technique that involves the use of light to analyze the chemical and physical properties of compounds. It can be used to determine the concentration of substances in a sample, as well as to identify compounds based on their absorption and transmission spectra. UV/VIS spectroscopy is a critical tool in many industries, including pharmaceuticals, food and beverage, and environmental monitoring. It requires specialized knowledge and training to operate and interpret data, making it a specialized skill.
