Basic principles:
Spectrophotometer analysis is based on the selective absorption of electromagnetic radiation by substances with different molecular structures.
The application of electromagnetic radiation spectrum region is usually ultraviolet-visible spectrophotometer in 200nm~800nm.
The use of microprocessor control technology to make qualitative and quantitative analysis of substances in the UV-visible spectrum region is a necessary multi-purpose analytical instrument in conventional laboratories.

Features:
