UV visible spectrophotometer is a very important analytical instrument, which has wide and important applications in scientific research fields such as physics, chemistry, biology, medicine, materials science, environmental science, as well as in modern production and management departments such as chemical engineering, medicine, environmental testing, metallurgy, etc.

The principle of UV visible spectrophotometer is:

The UV visible absorption spectrum of a molecule is the absorption spectrum generated by the electronic energy level transition of certain functional groups in the molecule after absorbing UV visible radiation. It is a band spectrum that reflects information about certain functional groups in the molecule. Qualitative analysis can be conducted using standard spectrograms combined with other methods.
