Preferred Label : microscopy, Energy-Filtering transmission electron;
MeSH definition : An analytical transmission electron microscopy method using an electron microscope
fitted with an energy filtering lens. The method is based on the principle that some
of the ELECTRONS passing through the specimen will lose energy when they ionize inner
shell electrons of the atoms in the specimen. The amount of energy loss is dependent
upon the element. Analysis of the energy loss spectrum (ELECTRON ENERGY-LOSS SPECTROSCOPY)
reveals the elemental composition of a specimen. It is used analytically and quantitatively
to determine which, how much of, and where specific ELEMENTS are in a sample. For
example, it is used for elemental mapping of PHOSPHORUS to trace the strands of NUCLEIC
ACIDS in nucleoprotein complexes.;
