Gas analyzer TG-DTA

Simultaneous Thermal Analysis (STA) generally refers to the simultaneous application of thermogravimetry (TG) and differential thermal analysis (DTA) to one and the same sample in a single instrument. The measurement conditions are perfectly identical for the TG and DTA signals (same atmosphere, gas flow rate, vapor pressure of the sample, heating rate, thermal contact to the sample crucible and sensor, radiation effect, etc.). Rigaku adopts the horizontal differential triple-coil balance system which is the mainstream mechanism because the thermal drift which apparent mass change with increasing temperature becomes negligibly small. TG can provide information about physical phenomena, such as second-order phase transitions, including vaporization, sublimation, absorption, adsorption, and desorption, while DTA can provide information on the transformations that have occurred, such as glass transitions, crystallization, melting and sublimation. The Infrared heating furnace can be selected for quick heating and cooling. The sample is heated by infrared radiation emitted from infrared lamp. The sample holders are easily replaced adopting the plug-in type holder. When replacing sample holders due to spillage, maintenance is quite simple. The auto sample changer can be attached to the standard TG-DTA. We can set maximum 24 samples and aside from continuous measurements, it can also perform single measurement as well as interrupt-a-sequence measurement.
