The combination of Evolved Gas Analysis (EGA) and Thermal Analysis delivers extremely valuable information for material characterization in research, development, production and quality assurance for ceramics, metals, polymers, pharmaceuticals, etc.
In addition to the detection of mass changes and heat flux values, the evolved gases can be identified and quantified simultaneously during one measurement.
Now, NETZSCH offers a new cost-effective alternative to the high-performance Skimmer coupling system with its excellent detection sensitivity for large molecules, fragments and metal vapors.
The QMS 403 Aëolos® is a new MS capillary system for routine analysis of permanent gases and less condensable decomposition products. This system is optimized for Thermal Analysis by:

STA-QMS measurement on Dicyclopentadiene
The sample (3.3 mg) was measured in He atmosphere with a heating rate of 10 K/min. Several TG steps were observed before the sublimation takes place between 250 and 300 °C. It can also clearly be seen that the molecular peak with mass number 132 amu (C10H12) can be detected.
STA-QMS measurement on FEP
A FEP sample (fluorinated ethylene-propylene copolymer) with 7.9 mg mass was investigated with a heating rate of 10 K/min in He atmosphere. During the 2-step decomposition, the monomers tetrafluor-ethylene (100 amu) and hexafluor-propylene (150 amu) were detected.
NETZSCH offers
precision thermal analysis instruments including advanced dilatometers (with
a new basic R&D/QC dilatometer),
