When materials are heated, gases are released due to evaporation or decomposition once a critical temperature is reached. Adding hyphenated techniques allows for the generation of crucial information regarding the nature and composition of the gases evolved during a mass loss.
Dr. Jürgen Blumm will dive into the state-of-the-art Evolved Gas Analysis and highlight applications of combining thermal analyzers with Fourier Transform Infrared Spectrometers (FT-IR), Quadrupole Mass Spectrometers (QMS) or Gas Chromatograph (GC) with mass spectrometer as detector (GC-MS systems).
After his talk, Dr. Blumm will answer your questions about Evolved Gas Analysis.
Dr. Jürgen Blumm studied solid-state physics at the University of Würzburg. He finished his Master in 1995. Then, he started working as a scientist at the NETZSCH Applications Laboratories. From 2001 to 2008, he was head of the applications laboratories at the NETZSCH headquarters in Selb. Parallel to this, he finished his PhD in the field of thermal characterization of ceramics prior to during and after the sintering process. In 2008, he moved to a management position. He is responsible for Sales, Marketing & Applications for the Analyzing&Testing Business Unit at NETZSCH.
He is the author of a approx. 40 scientific papers and several contributions to scientific books and presented more than 100 lectures on scientific conferences and seminars. He holds more than 10 patents.
Jürgen Blumm is a well-known expert in the field of Thermal Analysis, Thermophysical Properties Testing and Evolved Gas Analysis. He has more than 25 years of experience in technology, instrumentation and application.
By coupling a Thermobalance (TG, TGA), Simultaneous Thermal Analyzer (STA, TGA-DSC) or Dilatometer (DIL) with a Quadrupole Mass Spectrometer (QMS), it is possible to detect and identify evolved gases in exact time correlation with TGA or STA signals.
The GC (gas chromatograph) separates gas mixtures based on the differences in component distribution between a stationary phase (e.g., inner coating of a capillary) and a mobile phase (e.g., He). At the outlet of the GC column, the MS is connected. Using the pre-separation of the gases by the GC as a basis, the MS provides detailed structural information about the compounds released.
