Abstract

An EGA method measuring the vapours and gases containing organic carbon was applied to study paper ageing. In a DuPont 916 Thermal Evolution Analyzer the original and aged paper samples were heated in a temperature programmed furnace, and the evolving volatiles are swept by an inert gas into a hydrogen flame ionization detector. The low temperature section of the EGA curves (before the main decomposition step) is sensitive to the slight changes caused by ageing. In the case of naturally aged papers (stored at room temperature), the older the samples of the same quality were, the more intensive was the evolution of organic substances at temperatures below 250 ‡C. The differences among samples subjected to accelerated (thermal) ageing were an order of magnitude smaller. This points to the differences between the processes of natural and thermal againg.
