@juanjuanlabamy: 190-1100nm UV Visible Spectrophotometer-PTM005 190-1100nm UV-Vis Spectrophotometer is an essential analytical instrument used to measure the absorption of ultraviolet and visible light by a sample. The "190-1100nm" range signifies its capability to analyze light from the deep ultraviolet (190nm) through the entire visible spectrum and into the near-infrared (1100nm). The instrument operates on the Beer-Lambert Law, which states that the amount of light absorbed by a substance is directly proportional to its concentration and path length. Its core components include a light source (typically a deuterium lamp for UV and a tungsten lamp for Vis), a monochromator to select specific wavelengths, a sample compartment, and a detector. This versatile tool is fundamental in numerous fields. In chemistry and biochemistry, it is used for quantifying nucleic acids, proteins, and determining reaction kinetics. In pharmaceuticals, it ensures drug quality and purity. Environmental scientists use it to detect pollutants in water, while it also finds applications in material science and quality control. Key features often include high wavelength accuracy, photometric accuracy, and user-friendly software for data acquisition and analysis. Its ability to provide rapid, non-destructive, and quantitative analysis makes the 190-1100nm UV-Vis Spectrophotometer a cornerstone instrument in modern research, industrial, and educational laboratories worldwide.
