UV-visible spectrophotometer

Instrument Model: UV-540

Manufacturer: United States UNICAM Company

Purchase date: July 2003

Main Specifications:

1. Wavelength range: UV-visible (190~900nm)

2. Wavelength accuracy: ±0.3nm

3. Wavelength reproducibility: ±0.1nm

uses:

With data processing software, it can automatically complete data processing and get 1, 2, 3, 4 order spectrum; it can be used for dual-wavelength, three-wavelength experiments; Equipped with sample powder cup, it can scan the spectrogram of solid sample and powder sample; In the case of higher or lower absorbance, more accurate measurement results can be obtained. There are two working methods: scanning the UV-visible absorption spectrum of the sample between 195nm and 900nm; determining the absorbance of the sample at the specified wavelength. It can then make a structural analysis and qualitative quantitative analysis from available Visible-ultraviolet light absorption spectrum of the chemical substances and absorbance of the sample at the specified wavelength. With a powder cup attachment, the instrument can not only determine the solution, but also scan samples and get their absorbance directly in solid state and powder state. It is Widely used in organic chemistry, polymer chemistry, chemicals, pharmaceuticals, materials and other disciplines.
