High Resolution Thermogravimetric Analysis - a New Technique for Obtaining Superior Analytical Results

Resolution, the ability to separate closely occurring events, is an important criterion for most analytical instrument techniques since it effects the ability to obtain accurate, quantitative results. Thermal Analysis techniques are no exception to this basic rule. A good example is thermogravimetric analysis (TGA) which measures weight changes with temperature, providing information about material compositional analysis and thermal stability. Resolution of successive TGA weight losses is important for obtaining accurate, reproducible weight change values, as well as accurate component identification in the evolved decomposition gases by FTIR (Fourier transform infrared) or mass spectroscopy.
