UV-VIS Spectrophotometer

Introduction of UV-VIS Spectrophotometer

The absorption of light by substances is selective. The UV-VIS spectrophotometer is an instrument that uses the absorption of light in a certain wavelength range by the molecules or ions of the substance to analyze the composition and structure of the substance. The basic structure is light source, monochromator, absorption cell, detector and signal display system. DRAWELL's UV-VIS spectrophotometer can be divided into single beam spectrophotometer and double beam spectrophotometer according to the instrument structure and divided into visible spectrophotometer and ultraviolet spectrophotometer according to the wavelength and atmosphere of the absorbed light. UV-VIS spectrophotometer has been widely used in production, education and research in the fields of biology, chemical engineering, metallurgical geology, mechanical manufacturing, environmental protection, agriculture and forestry.

Applications of UV-VIS Spectrophotometer

The UV-VIS spectrophotometer is a very important analytical instrument, and its two main functions are quantitative analysis and qualitative analysis. Whether in scientific research fields such as physics, chemistry, biology, medicine, materials science, and environmental science, or in modern production and management departments such as chemical engineering, medicine, environmental testing, and metallurgy, UV-VIS spectrophotometers have a wide range and important application.
1. Material verification
2. Contrast with standards and standard maps
3. The consistency of the absorption coefficient of relatively large absorption wavelength
4. Research on reaction kinetics
5. Purity inspection
6. Determination of hydrogen bond strength
7. Determination of complex composition and stability constant
