Abstract
An electronic probe microanalyzer measures the particle size of an inclusion in metal by scanning an area of ζ5mm at an arbitrary position on the surface of a master, defines a calibrating curve indicative of relation of the particle size of inclusion in metal with the emission spectrum intensity of an element constituting the inclusion in metal based on the measured particle size of inclusion in metal, specifies the inclusion in metal existing at an emission spot based on the data of emission spectrum intensity of an element existing at the emission spot on the surface of a sample to be measured, and then measures the particle size of a specified inclusion in metal based on the data of emission spectrum intensity and the calibrating line.
