What is Thermogravimetric Analysis?
Thermal gravimetric analysis (TGA) uses a highly sensitive balance to monitor the weight loss of a sample vs time, temperature, and gas environment. FAI also collects heat flow information (SDTA) to determine whether events are endothermic or exothermic and to provide accurate calibration using the melting points of high purity metal standard reference materials. 99.999% or higher purity gallium, indium, zinc, lead, tin, and silver are used for the most accurate calibration.
The data from these tests can be used to determine:
• Material Composition
• Percent Volatiles
• Mineral Content
• Base Polymer Content of Plastics
• and more
Applications
TGA analysis provides a wealth of chemical information. Measuring how much weight is lost at a specific temperature and gas environment allows us to identify precisely what group of compounds is volatilizing. Measuring the total weight lost tells us how much mass of the compound was in the sample. There are nearly limitless uses for thermogravimetric analysis. TGA analysis can be used to analyze tire rubber chemistry, determine the carbon black content of a master batch, determine the composition of a cosmetic, understand thermal stability of pharmaceuticals, find the triggering temperature of a blowing agent, determine the melting temperature of alloy solders, find the vapor pressure curve for lubricants, and more.
FAI offers traditional gravimetric ashing testing as well as a computer-controlled thermogravimetric analyzer for ultra-precision thermogravimetry. We also have the capability to perform simultaneous differential thermal analysis (SDTA) with our thermogravimetric analyzer.
