Preferred Label : spectroscopy, electron energy-loss;
MeSH definition : A technique for analysis of the chemical composition of molecules. A substance is
bombarded with monochromatic ELECTRONS. Some of the electrons passing through the
specimen will lose energy when they ionize inner shell electrons of the atoms in the
specimen. The energy loss is element dependent. Analysis of the energy loss spectrum
reveals the elemental composition of a specimen. ENERGY-FILTERED TRANSMISSION ELECTRON
MICROSCOPY is a type of electron energy loss spectroscopy carried out in electron
microscopes specially outfitted to analyze the spectrum of electron energy loss.;
MeSH synonym : electron energy-loss spectroscopy; energy-loss spectroscopy, electron; electron energy loss spectroscopy; spectroscopy, electron energy loss;
Origin ID : D046590;
