Thermogravimetric analysis - Model Q50 by TA Instruments
Thermogravimetric Analysis (TGA) is a type of testing that is performed on samples to determine changes in weight in relation to changes in temperature.
Such analysis relies on a high degree of precision in three measurements: weight, temperature, and temperature change. As many weight loss curves look similar, the weight loss curve may require transformation before results may be interpreted. A derivative weight loss curve can be used to tell the point at which weight loss is most apparent.
TGA is commonly employed in research and testing to determine characteristics of materials such as polymers, to determine degradation temperatures, absorbed moisture content of materials, the level of inorganic and organic components in materials and solvent residues.
The custom-designed furnace on the Q50 features a low mass, rugged heater windings and proprietary heater control technology. This results in rapid, accurate and precise temperature programming over a wide range of temperatures.
The heart of the Q50 is the accurate and ultra-reliable, vertical thermobalance housed in a temperature-controlled environment. It uses the proven ‘null-balance’ principle, where an optically active servo loop maintains the balance arm in the horizontal reference (null) position by current regulation in a transducer coil.
