Laser marking process change

The two different ionisation laser wavelengths result in markedly different mass spectra. These mass spectral differences are a valuable aid in the unambiguous identification of the additives. Wright and co-workers [61] also reported that the spectra obtained show not only that it is possible to directly detect these additives in the polymer formulations, but also that chemical changes undergone by antioxidants, due to either processing or ageing, can also be observed. [Pg.33]
