Abstract
An improved X-ray analyzer may be made portable and provide accurate positioning capabilities to permit precise location on a sample of a measurement point. An imaging device is provided to allow the user to observe a position at which primary X-rays generated by an X-ray source are to be irradiated onto the sample, and a display device is provided for displaying an image thereof. The display device displays a fluorescent X-ray spectrum taken at a measurement point on the sample in accordance with an output of an X-ray detector at the same time as displaying the sample image.
Claims36
A fluorescent X-ray analyzer for performing X-ray analysis using a fluorescent X-ray method, the fluorescent X-ray analyzer comprising:
- an X-ray generating source;
- a collimator for irradiating only part of an X-ray luminous flux generated by the X-ray generating source onto a sample to be measured;
- an X-ray detector for detecting a fluorescent X-ray produced by the sample to be measured;
- an imaging device for obtaining an image of the sample to be measured;
- a display device for displaying the sample image;
- and a housing in which the X-ray generating source, the collimator, the X-ray detector, the imaging device and the display device are contained.
A fluorescent X-ray analyzer comprising:
- an X-ray generating system;
- X-ray detecting means for detecting X-rays emitted by the sample;
- a processing circuit for producing an X-ray spectrum based on the detected X-rays;
- an imaging device for producing an image of the sample, including a region of the sample from which the X-rays are emitted;
- a display device for displaying the sample image and the X-ray spectrum;
- a memory device for storing one or more sets of sample images and corresponding X-ray spectra;
- and a housing containing therein the X-ray generating system, the X-ray detecting means, the processing circuit, the imaging device, the display device and the memory device.
A portable fluorescent X-ray analyzer comprising:
- an X-ray generating source for irradiating a sample with X-rays;
- an X-ray detector for detecting fluorescent X-rays produced by the sample in response to irradiation of the sample by the X-ray generating source;
- an imaging device for producing an image of the sample;
- a display device for displaying the sample image;
- and a housing in which the X-ray generating source, the X-ray detector, the imaging device and the display device are contained so that accurate sample positioning may be performed without obstruction by the housing by referring to the sample image displayed on the display device.
