Spectrophotometry

Spectrophotometry is a technique used to measure the amount of light absorbed by a substance as a function of the wavelength of the light. It is commonly used in scientific research and industry to analyze the chemical composition of a sample. A spectrophotometry device, also known as a spectrophotometer, is an instrument that is used to measure the intensity of light as it passes through a sample. There are several types of spectrophotometers, including UV-visible spectrophotometers, which measure the absorbance of ultraviolet and visible light, and infrared spectrophotometers, which measure the absorbance of infrared radiation. Spectrophotometers are widely used in a variety of applications, including chemical analysis, environmental monitoring, and quality control.
