What is 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 substance’s molecules or ions to analyze the substance’s composition and structure. The basic structure is a 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. The following are the wide range and important application of UV-VIS spectrophotometers:
- Material verification.
- Contrast with standards and standard maps.
- The consistency of the absorption coefficient of the relatively large absorption wavelength.
- Research on reaction kinetics.
- Purity inspection.
- Determination of hydrogen bond strength.
- Determination of complex composition and stability constants.
