3. UV-visible absorption spectrometry

Please refer to the article in the Analyse et caractérisation des Techniques de l'Ingénieur.

UV-visible absorption spectrometry is much more sensitive than infrared spectrometry, yet it is not used as a routine method for polymer identification. This is because, unlike infrared spectra, UV-visible spectra of polymers generally do not display absorption bands that are sufficiently characteristic to allow samples to be identified.

The main applications of UV-visible spectrometry in the field of polymers relate more specifically to the analysis of additives, colorants and pigments, and the analysis of polymer...
