ECE Testing Equipment
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: increased temperature of the transfer system (300 °C)

System and Experiments
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.
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.
