Mass spectrometry determines the effects of drugs in the body, identifies illegal steroids in an athlete, and determines the age and origin of once-living material in archeology. [Pg.20]

Examples of polysiloxane degradation studies include the role of surfactants in suppressing aging of silica-PDMS gels, " the effects of pigments on the stability of montmorillonite-PDMS composites, and the use of NMR and mass spectrometry to characterize degradation processes. " " ... [Pg.98]

Thermogravimetric analysis (Chapter 2), for example, has been used in studies of polymer degradation, activation energy, phase transitions, and also for the effect of antioxidants on polymer ageing and polymer lifetime studies. Coupling this technique with mass spectrometry (Chapter 3) enables further information to be obtained on the nature of polymer decomposition products, which accompany polymer weight changes. [Pg.3]
