Abstract:
1. An electron probe X-ray analyzer for analyzing a sample by directing a sharply focused, accelerated electron beam at the sample and detecting produced characteristic X-rays, said electron probe X-ray analyzer comprising: WDS quantitative means for performing quantitative analysis using a wavelength-dispersive X-ray spectrometer (WDS); EDS quantitative means for performing quantitative analysis using an energy-dispersive X-ray spectrometer (EDS); identification means for identifying compounds at analysis points from results of quantitative analysis performed by the EDS quantitative means; condition-setting means for setting analytical conditions to be applied to the quantitative analysis performed by the WDS quantitative means at the analysis points based on results of identification of the compounds performed by the identification means on the basis of results of the quantitative analysis performed by the EDS quantitative means; and storage means for storing (i) the compounds at the analysis points identified by the identification means, (ii) the analytical conditions set by the condition-setting means, and (iii) results of the measurement at the analysis points performed under the analytical conditions set by the condition-setting means such that these three sets of items are interrelated.
