Claim:
1. An analyzing apparatus for analyzing compositions of particulate matter based on a fluorescent X-ray generated from the particulate matter, the analyzing apparatus comprising: an emission unit configured to emit an exciting X-ray, the exciting X-ray exciting the particulate matter to generate the fluorescent X-ray; a collection filter configured to collect the particulate matter; a calibration base material provided together with the collection filter in a measurement area to which the exciting X-ray is emitted when performing a calibration; a detection unit configured to detect an X-ray generated from the measurement area, the detection unit detecting a calibration X-ray generated from the measurement area by emitting the exciting X-ray to the collection filter and the calibration base material when performing the calibration, the calibration base material having a base material and a calibration specimen supported on the base material; and a composition analysis unit configured to generate span calibration data for each element to be measured by using a base fluorescent X-ray as the calibration X-ray when performing the calibration, the base fluorescent X-ray being generated by emitting the exciting X-ray to the calibration specimen, and analyze the compositions of the particulate matter based on the span calibration data and a measured value of X-ray detected by the detection unit when analyzing the compositions of the particulate matter.
