Utilization of Existing Techniques

Published information on characterization of seven different materials has been gathered from the literature to serve as a guide to the use of existing analytical techniques. These seven materials are copper, silicon, gallium arsenide, potassium chloride, zinc sulfide, anthracene, and trace element glasses. Collectively they represent an extremely broad spectrum of analytical problems and illustrate both strong and weak points in the application of the present state of the art of measurement of composition. [Pg.416]

The results, summarized in Tables 2-6, do not necessarily represent optimum performance, but they are fairly typical of published information on practical samples of highly purified materials. The notes of Tables 3-6 are quite representative of experience with different techniques on materials with impurities at levels of 500, 50, 1, or 0.02 ppm. [Pg.416]
