Extract

Several techniques have been developed for the quantitative microchemical analysis of thin foils. These procedures require that in an alloy AB the measured intensity ratio, IA/IB frora the foil be independent of foil thickness. Cliff and Lorimer find that this condition is met in all cases they have examined whereas Jacobs and Baborovska show data where absorption of longer wavelength X-rays was apparent.

The present study was undertaken to evaluate these procedures for the combination of a scanning transmission electron microscope (JEOL JSEM 200) and an energy dispersive analyzer (Ortec).
