<p><em>Electron Energy Loss Spectroscopy (EELS)</em> is a high resolution technique used for the analysis of thin samples of material. The technique is used in many modern transmission electron microscopes to characterise materials. This book provides an up-to-date introduction to the principles and applications of EELS. Specific topics covered include theory of EELS elemental quantification EELS fine structure EELS imaging and advanced techniques.</p>
