Thermogravimetric Analysis

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.
