A transistorized 400-channel multichannel analyzer attached to the electron probe microanalyzer has increased the versatility and decreased the time required for many analyses. Three types of application are illustrated. The multichannel analyzer replaces a scanning crystal spectrometer for quick identification and semiquantitative analysis of components. Quantitative analysis by mathematical unfolding of the energy spectra is made practical by the fast data collection of standard and unknown spectra; comparison of results by unfolding and from crystal spectrometer data shows differences of less than 4% of the amount present. Quantitative two-dimensional topographic display is obtained by multiscaler operation of the 400-channel memory system.
