摘要： In an analyzing apparatus for analyzing compositions using a fluorescent X-ray in the atmosphere, a calibration to eliminate influences caused by a time-dependent change is performed. The analyzing apparatus includes an emission unit, a detection unit, an environment measurement unit, and a time-dependent change calculation unit. The emission unit emits a primary X-ray. The detection unit detects an intensity of a secondary X-ray passing through the atmosphere. The environment measurement unit measures an environment parameter defining the atmosphere. The time-dependent change calculation unit calculates a time-dependent change of the intensity of the secondary X-ray between a first timing and a second timing, based on a first environment parameter, a first intensity of the secondary X-ray, a second environment parameter, and a second intensity of the secondary X-ray.

摘要： To more accurately output a signal related to a source of particulate matter floating in the atmosphere, an analyzer is equipped with a mass concentration measuring unit, an element analysis unit, and a source-related signal output unit. The mass concentration measuring unit measures the mass concentration of fine particulate matter (FP) in the atmosphere. The element analysis unit analyzes an element contained in the FP. The source-related signal output unit outputs a signal related to the source of the FP on the basis of the mass concentration measurement result from the mass concentration measuring unit, and the analysis result for the element contained in the FP from the element analysis unit.

The detection unit detects X-rays generated from the measurement area. The detection unit detects a calibration X-ray when performing the calibration. The composition analysis unit generates calibration data by using the calibration X-ray when performing the calibration. The composition analysis unit analyzes compositions of the particulate matter based on the calibration data and a measured X-ray detected by the detection unit when analyzing the compositions of the particulate matter.

摘要： The X-ray detection apparatus is equipped with an X-ray irradiation unit, an X-ray detector, a movable collimator and a shield for blocking X-rays. The shield blocks X-rays, which are to enter the X-ray detector directly from the X-ray irradiation unit. The shield also blocks fluorescent X-rays and scattered X-rays generated by irradiation of the collimator with X-rays. In such a manner, it is possible to prevent X-rays other than fluorescent X-rays from the sample S from being detected by the X-ray detector. The shield is joined with the collimator, so that the collimator and the shield move as a unit. It is possible to locate the shield even in a downsized X-ray detection apparatus.
