Spectromètre UV/Visible lambda 25 Perkin Elmer

Principle

This spectral analysis is based on ultraviolet / visible absorption (UV / Vis)

The spectrum of interest here ranges from 190 nm (wavelength close to UV) to 1100 nm (dark red wavelength).

The interpretation of these bands in relation to their intensity, their wavelength, their shape as well as the comparison with a library of reference spectra (more than 15,800 spectra), will make it possible to highlight at least the chemical family (ester, acid, urethane ...) and very often the exact nature of the compound analyzed.
