Product description Evolved Gas Analysis
Almost half a century of experience in coupling thermal analysis with gaseous analysis!
With thermogravimetry you can measure mass change of a sample as a function of time or temperature. However, it is not possible to identify gaseous products produced during the heating program with this method. Mass spectrometry, Fourier transform infrared (FT-IR) spectroscopy or a combination of gas chromatography and mass spectrometry (GC-MS) can provide a solution for the analysis of the gas formation at the outlet of the thermal microbalance.
40 years of coupling with mass spectrometers
By coupling a thermobalance (TG, TGA), simultaneous thermal analyzer (STA, TGA-DSC) or dilatometer (DIL) to a quadrupole mass spectrometer (QMS), it is possible to detect and identify gaseous products in exact time correlation with TGA or STA signals. NETZSCH has over 40 years of experience combining thermogravimetry with mass spectrometry and offers proven coupling systems. The unique SKIMMER coupling, the capillary coupling for the QMS 403 Aëolos Quadro and the GC-MS coupling.
25 Years of Coupling with FT-IR Systems
The 403 Aëolos Quadro quadrupole mass spectrometer is a new compact mass spectrometer, with a heated capillary inlet system for analysis of gases and in particular volatile degradation products of thermal analysis. This system is optimized for coupling to differential scanning calorimeters (DSC), thermogravimetric analyzers (TGA) and dilatometers (DIL). The software is unique: fully integrated MS software for measurement and analysis.
The combination with FT-IR (Fourier transform infrared) spectroscopy has become an absolute must, especially in polymer production and chemical and pharmaceutical industries. Netzsch Analyzing & Testing has been working together with the well-known spectrometer manufacturer, Bruker Optics GmbH, since 1993. The FT-IR coupling is “more than the sum of the substances or ingredients”. Let the intelligent hardware and software designs work for you!
10 Years of Coupling with GC-MS Systems
The GC (gas chromatograph) separates gas mixtures based on the differences in molecular distribution, using a stationary phase (capillary coating) and a mobile phase (helium as carrier gas). Volatile gas components or molecules have a low affinity with the stationary phase. Gases with a high affinity for the stationary phase will follow with a significant delay (“retention time”). A simple example, let a group of ladies and gentlemen walk into the Kalverstraat at the same time and you will see that the gentlemen come out earlier at the end of the street. The ladies are slowed down by the shops on the way. The MS is connected at the exit of the GC column. Separation of the gas components by means of the GC as a basis offers the possibility to measure the various components purely with the MS.
Other coupling solutions are, for example, humidification systems for adding relative or absolute moisture contents.
