SOLIA TGA-MicroGC/MS Interface

Technology: TGA interface


SOLIA TGA-MicroGC/MS Interface. Coupling any thermogravimetric analyzer (TGA) with MicroGC/MS instrument.


SOLIA is a SRA MicroGC/MS solution ready to be coupled to a TGA. The heated transfer line is designed to analyze the evolved gases. The configuration includes heated membrane filter that protects the analytical module injector from heavy compounds and residues.
The µTCD of each MicroGC module can be coupled to an Agilent quadrupolar mass spectrometer which makes possible an easy identification of each separated compound. The identification is simply made using mass spectrum comparison with the NIST database.
The TGA/MicroGC coupling is the perfect solution for fast qualitative and quantitative analysis of evolved gas from a polymer or solid sample.

Technical specification:
  • MicroGC/MS coupling;
  • Automatic valve selection of the channel coupled to MSD before or during the sequence;
  • Configurable MicroGC with up to 3 modules;
  • Less than 3 minutes of analysis time;
  • Heated interface with a software programmable valve.
Developed by SRA, SOPRANE II performs the complete management of an analysis, from the sampling to the transmission of the results. A powerful graphical environment provides effectiveness and ease of use: is possible to define a method and a sequence of analysis, to follow the trends for specific compounds during a TGA analysis. Soprane II manages the mass spectrometer and its Agilent Masshunter software and compiles all results in a same report.
Application notes
Study of a Biomass Sample by TGA-GC/MS and TGA-Micro GC/MS

Evolved compounds of biomass can be easily characterized by TGA coupled to a GC/MS (heavy and medium compounds) and MicroGC/MS (permanent and light compounds).

These techniques can be used to characterize the structure and composition of the various gases evolved from the thermal decomposition of biomass feedstocks, and hence help assess their potential as a source of energy.
