Evolved Gas Analysis (EGA)

With the coupling of a thermal balance and a gas analyzer like a FTIR spectrometer (Fourier Transform Infrared) or a Quadrupole-Mass-Spectrometer a very powerful analytical instrumentation is used which gives information from the thermal balance (TGA) or simultaneous thermal analyzer (STA) as well as from the spectrometer simultaneously.

The optional Pulse-Analysis injects an exactly predetermined amount of gas into the Thermobalance (TGA) or Simultaneous Thermal Analyzer (STA). This enhances the measurement possibilities significantly.

Typical coulings for simultaneous measurements are:

• TG-DSC-MS (Thermogravimetry, Differential Scanning Calorimetry, Mass Spectrometer)
• TGA-MS (Thermal Balance coupled with Mass Spectrometer)
• TG-DSC-GC/MS (Thermogravimety, Differential Scanning Calorimetry, Gas Chromatography / Mass Spectrometry)
