Light Microscopys (SEM). A look at Chapter 5 on the SEM will quickly prove that this change is at least partly justified. These instruments will resolve detail one-tenth as large (20 nm = 0.02 μm) as that resolved by the light microscope, and the in-focus depth of field for the SEM is 100–300 times that of the light microscope.

Aspiration

Scanning Electron Microscopycludes all information relating to topographical features, morphology, habit and distribution, identification of differences based on chemistry, crystal structure, physical properties, and subsurface features, among others.

It is sensitive and quantitative, and signals can be obtained from nearly every element.

Radioisotope TechniquesA wide spectrum of radiochemical techniques can be employed for the characterization of surfaces. in broad terms these techniques can be separated into the two fields of tracer analysis and activation analysis.

Introductione developed for very high relative sensitivity, and the values determined were average values. Sampling procedures were devised which eliminated the so-called sampling error. However, in the last decade or so, a number of developments have shown that, for many purposes, the distribution of defects w
