Patent ID: 10989677

Abstract:
Provided is a fluorescent X-ray analysis apparatus, including: a collecting portion configured to drop a liquid droplet onto a substrate having an object to be measured on a surface thereof and move the dropped liquid droplet on the surface of the substrate to collect the object to be measured into the liquid droplet; a drying portion configured to dry the liquid droplet so that the object to be measured is held onto the surface of the substrate; an analysis portion configured to irradiate the object to be measured with an X-ray and perform quantitative analysis of an element contained in the object to be measured based on a fluorescent X-ray output from the object to be measured; a beam sensor configured to emit a laser having a band shape for detecting an amount of the liquid droplet separated from the collecting portion before the liquid droplet is dried after the object to be measured is collected; and a calculating portion configured to calculate a correction coefficient for correcting the amount of the liquid droplet or a quantitative analysis value of the object to be measured based on a detection result of the beam sensor.
