TGA/DTA/DSC/Cp RT to 1500°C. Then go to the analysis tab. The analysis methods TG. Description of basic. The evolved gases from PET were benzoic acid, carbon dioxide and carbon monoxide, while those from PBT were. Optical dilatometry allows the investigation of sintering processes and the thermal linear expansion, especially of anisotropic and fragile materials as well as of samples with complicated geometries. Technologies for Licensing; Research Facilities; Areas of Expertise; Job Opportunities; Contact. The DTA curve. Dear Prince Thomas, TGA measures weight change of a sample over a temperature range, DSC measures heat flow of a sample over a temperature range, and DTA measures heat differences between a. In this work, Raman spectra were taken continuously from xerogel TiO 2 in a heating process similar to that in TGA/DTA. Recently, zinc oxide nanoparticles (ZnO NPs) have been used in several biological and industrial applications due to their low toxicity, high efficiency, biocompatibility, and cost-effectiveness. Copy the temperature column completely from excel and paste it in a new origin worksheet as X-axis. The thermal studies have been done up to a tempera-ture of 1000ºC showing weight loss of 14% and 17% which is due to loss of hygroscopic water and dehydroxylation. $24,000.
