Thermogravimetric analysis, or TGA, measures the weight of a material sample in an atmosphere of nitrogen, helium, air or other gas. It measures the change in mass of the sample over time as a result of programmed temperature profile
The temperatures in TGA can range from ambient to over 2000°C, which is why specialist instruments are crucial to this method.
Thermogravimetric analysis has various applications, such as:
• Evaluating the thermal stability of a material in different atmospheres
• Determining weight change in decomposition reactions, for quantitative composition analysis
• Can be coupled to analytical techniques such as FTIR, MS for evolved gas analysis
• Identifying plastics and organic materials compostiion
• Measuring the weight of inorganic fill materials in plastics, laminates, primers, paints and composite materials by burning off polymer resins
• Measuring fill materials added to foods, such as silica gels, calcium carbonate, cellulose and titanium oxide
• Determining the purity of inorganic compounds, organic materials and minerals
• Distinguishing different mineral compositions in broad mineral types such as boric acid and silica gels.
High-performance modular simultaneous TGA & DTA / DSC thermal analyser (ambient / 2400°C) The HIGHLIGHTS SETSYS Evolution is the standard for high performance TGA, TG-DSC and TG-DTA application.
