X-ray fluorescence - Wikipedia
X-ray fluorescence (XRF) is the emission of characteristic "secondary" (or fluorescent) X-rays from a material that has been excited by being bombarded with high-energy X-rays or gamma rays.
Artificial peaks in energy dispersive X‐ray spectra: sum peaks, …
2016年5月2日 · Sum peaks, escape peaks, and diffraction peaks are considered artificial or spurious peaks in energy dispersive X-ray spectrometry. Experimental examples are given, which showed that escape and diffraction peaks can add up to become sum peaks.
成分分析四大家—XRF、ICP、EDS、WDS - 知乎 - 知乎专栏
XRF 指的是 X射线荧光光谱仪，可以快速同时对多元素进行测定的仪器。 在X射线激发下，被测元素原子的内层电子发生能级跃迁而发出次级X射线（X-荧光）。 从不同的角度来观察描述X射线，可将XRF分为 能量散射型 X射线荧光光谱仪，缩写为 EDXRF或EDX 和 波长散射型 X射线荧光光谱仪，可缩写为 WDXRF或WDX，但市面上用的较多的为EDX。 WDX用晶体分光而后由探测器接收经过衍射的特征X射线信号。 如分光晶体和探测器做同步运动，不断地改变衍射角，便可获 …
Fitting Compton peaks from first principles in x‐ray fluorescence ...
2024年7月5日 · This study aims to provide a fitting method with grounded physics to model Compton peaks in a way that can be employed in the fitting of typical XRF spectra. The proposed method will undergo fitting against a diverse range of XRF spectra spanning the energy range from 10 to 50 keV, to justify its validity for XRF experiments.
This booklet gives a general introduction to X-Ray fluorescence (XRF) spectrometry and XRF analysis. It explains simply how a spectrometer works and how XRF analysis is done. It is intended for people new to the field of XRF analysis. Difficult mathematical equations are avoided and the booklet requires only a basic
Efficient Implementation of Peak Detection Algorithm for X-Ray ...
The accuracy of XRF spectrometers can be improved using an appropriate trapezoidal pulse shaping method. In this paper, an efficient trapezoidal filter architecture is presented. In addition, we present a hardware-efficient peak value detection algorithm.
2. Interpretation of XRF Spectra - Chemistry LibreTexts
Peaks arising from target element in X ray tube (again, Rh in this case) that may appear in all XRF spectra acquired on that instrument. Some energy is lost in this process so peaks show up at energies slightly less than characteristic X-ray tube target energies.
