On-Line Thermally Induced Evolved Gas Analysis: An Update—Part 1: EGA-MS
网页2022年5月30日 · EGA-MS showed a thermo-chemical conversion mass loss at a level of 30% with energy loss (torgas) at a level of 10%. Detailed analysis of thermodynamics, kinetics, and reaction products can provide valuable information about peanut shell pyrolysis reaction, which is essential for its efficient utilization.
Pyrolysis gas chromatography-mass spectrometry in environmental ...
网页2020年9月1日 · Evolved gas analysis (EGA-MS) involves the separation of degradation products from macromolecules according to the temperature at which they are formed rather than according to their volatilization temperature. This is achieved through a sequential macromolecules degradation that takes place in the pyrolyzer using a slow temperature ramp ...
Mass spectrometry for evolved gas analysis: An update
网页2018年4月4日 · In this review, recent applications of mass spectrometry for EGA (EGA–MS), selected among those published in 2016 and 2017, are reported to show how the characterization of the nature of volatile products released by a substance subjected to a controlled temperature program allows to prove a supposed reaction, either under isothermal or …
网页a classical analysis technique, thermally evolved gas analysis – mass spectrometry (EGA-MS), is employed to obtain an image of the nanoparticle–solvent interface, unraveling the molecules present on the surface. As the use of complementary techniques is urged, the validity of EGA-MS characterization is
On-Line Thermally Induced Evolved Gas Analysis: An Update—Part 2: EGA ...
网页2022年12月15日 · The on-line thermally induced evolved gas analysis (OLTI-EGA) is widely applied in many different fields. Aimed to update the applications, our group has systematically collected and published examples of EGA characterizations.
