Abstract:Simultaneous photothermal analysis (PTA), and differential thermal analysis (DTA) curves of inorganic compounds and organic polymers are presented. While the two techniques reinforce each other and provide complementary information, light emanating from the sample and detected by a photomultiplier tube provides features in the PTA thermograms not present in the DTA thermograms.
