Electron Energy-Loss Spectroscopy in the Electron Microscope

Electron energy-loss spectroscopy (EELS or ELS) has been used to investi­ gate the physical properties of solids for over 40 years in a handful of laboratories distributed around the world. More recently, electron micro­ scopists have become interested in EELS as a method of chemical analysis with the potential for achieving very high sensitivity and spatial resolution, and there is a growing awar...
