Wave spectrum and energy spectrum composite type X-ray fluorescence spectrophotometer

Abstract

The invention provides a wave spectrum and energy spectrum composite type X-ray fluorescence spectrophotometer. The wave spectrum and energy spectrum composite type X-ray fluorescence spectrophotometer comprises an X-ray source, a light filter switching mechanism, a sample moving platform, a sample cup, a diaphragm switching mechanism, a primary collimator switching mechanism, a dispersive crystalswitching mechanism, a secondary collimator switching mechanism, a gasflow type proportional counter, a scintillation counter, an SDD detector, a main control panel and a PC machine. The wave spectrum and energy spectrum composite type X-ray fluorescence spectrophotometer has the following advantages: detection or point/face scanning can be rapidly completed by using an energy spectrum function when the sample is subjected to integrated component analysis and distribution analysis, and the whole body or certain area of the sample can be subjected to element analysis and distribution analysisby a wave spectrum function, so that organic combination of the wave spectrum and energy wave spectrum functions is realized, the two functions can be applied to integrated element component analysisand distribution analysis of the sample, the characteristics of high resolution, rapidness, flexibility and combinability are achieved, the reliability of the analysis result can be improved and the detection efficiency can be improved obviously.

Description

Technical field: [0001] The invention relates to the technical field of X-ray fluorescence spectrometers, in particular to a composite X-ray fluorescence spectrometer with spectrum energy spectrum. Background technique: [0002] X-ray fluorescence spectrometer can perform non-destructive and rapid elemental analysis of the sample to be tested, and has been widely used in inorganic analysis fields such as geology, metallurgy, non-ferrous metals, building materials, and the environment. According to different spectroscopic methods, X-ray fluorescence spectrometers can be divided into wavelength dispersive (spectrum) and energy dispersive (energy spectrum) X-ray fluorescence spectrometers. Wavelength dispersive X-ray fluorescence spectrometer is divided into sequential type and fixed channel type. Sequential wavelength dispersive X-ray fluorescence spectrometer has the characteristics of high resolution and high flexibility, and has good analysis effect on light elements. Ene...

Problems solved by technology

However, due to the structure of the instrument, when analyzing the distribution of samples, only energy spectrum analysis can be used, and spectral analysis cannot be performed, which limits the scope of application of this instrument

Some wavelength dispersive X-ray fluorescence spectrometers on the market also have the function of distribution analysis, but they do not have the function of energy spectrum analysis. It takes a long time to perform distribution analysis
