X-ray fluorescence spectrophotometer

Abstract

The invention discloses an X-ray fluorescence spectrophotometer. The X-ray fluorescence spectrophotometer comprises a measurement cavity and an analysis module; the measurement cavity is a structure capable of being opened and closed, so that a sample is taken and placed; when being closed, the measurement cavity is sealed and isolated with outside; a sample disc, filter plates and a displacementdevice are arranged in the measurement cavity; multiple installation stations used for installing different light filters are arranged on the filter plates; a driving device is used for driving the sample disc and one filter plate to move corresponding to the other, so that the sample disc is aligned to the light filters on the filter plates; the analysis module comprises an X-ray generator and adetector; X-ray generated by the X-ray generator irradiates a sample in the sample disc after passing through the light filters; the detector is used for receiving fluorescence X-ray generated by thesample after being stimulated, so that a fluorescence spectrogram is formed; when being used, the X-ray fluorescence spectrophotometer is simple, rapid and safe in sample preparation, and performs non-destructive analysis on the sample; the sample can be repetitively used; the equipment use investment is low; and daily calibration is unnecessary.

Description

technical field [0001] The invention relates to the technical field of coal quality analysis equipment, in particular to an X-ray fluorescence spectrometer. Background technique [0002] At present, when testing arsenic and phosphorus in coal, it is necessary to carry out destructive sample preparation processes such as crushing, grinding, ashing, and digestion of coal samples, which takes a long time and produces chemical waste. The transfer of one pipeline to another will cause cross-contamination and material loss. Due to the destructive sample preparation process, the coal sample is disposable and cannot be further analyzed and studied after the test is completed. Contents of the invention [0003] In view of this, the object of the present invention is to provide an X-ray fluorescence spectrometer, so as to avoid destructive sample preparation for coal samples, save time, and avoid the generation of chemical waste. [0004] To achieve the above object, the present in...
