Spectometers Uv Vis Nir Spectroscopy

Spectroscopic principle of UV detector

UV-Vis spectroscopy measures how much ultraviolet and visible light a sample absorbs at different wavelengths. Since every molecule absorbs a unique pattern of wavelengths, this. Spectroscopy is the measurement and interpretation of electromagnetic radiation absorbed or emitted when the molecules or atoms or ions of a sample move from one energy state to another energy state. Its popularity comes from its versatility, simplicity, and broad applicability, as it can detect nearly every molecule under the right conditions.
