TGA Micro GC Fusion Coupling: What interest for the analysis of emitted gases?

Emitted gases TGA Coupling Micro GC Fusion. TGA is a thermal(thermo-gravimetric analysis or TGA) analysis technique commonly used in many fields, from quality control to research.

More and more, the characterization of the emitted gases is of interest and allows the understanding of phenomena observed during the TGA cycle.

Among these couplings, we frequently find the infrared and the mass in line. The MicroGC Fusion, thanks to a simple and fast analysis, brings a competitive and performing answer.

Indeed, the Micro GC Fusion allows a characterization of the emitted gases or EGA. From the simplest compounds: O2, N2, H2, CO, CH4, CO2, H20 …  to the most complex, BTEX, VOC, sulfur compounds. The analysis in less than 3 minutes is compatible with TGA cycle times.

Through this poster, find three common applications and discover the advantages of the TGA coupling with the Micro GC.

  • « TPR – temperature programmed reduction » – Reduction of a catalyst exposed to hydrogen: monitoring of hydrogen consumption and water production (H2O)
  •  « TPO – temperature programmed oxidation » – Measurement of the oxidation of a metal, the behavior of a hydrocarbon during combustion
  •  « Dry gazeification » – Monitoring of CO concentration during gasification under CO2

Micro GC is a technique that can be coupled with TGA and has many advantages :

  • Easy to use
  • Rapid analysis in less than 2 minutes
  • Allows the analysis of simple or complex gases thanks to the complementarity brought by the various modules
  • Linearity of the ppm at 100%.
  • Easy quantification, excellent stability

Thanks to CHEMLYS’ expertise, you will be able to easily implement an efficient coupling. We take into account the constraints of sampling and gas routing from the TGA to the MicroGC.
