“…Marek Polasik investigated the relationship between valence electronic configuration and Kβ/Kα intensity ratio. Santosh Mirji et al showed that K‐L vacancy transfer probability depends strongly on the crystal structure of compounds. For most XRF analysis software, however, these parameters are assumed to be the same for different types of samples .…”

A method for improving the accuracy in X‐ray fluorescence spectroscopy analysis with pressed pellets was established through matching the calibration standards by the Kβ/Kα ratios. The Kβ/Kα ratios of four major elements (Al, Si, Ca, and Fe) were measured in 14 certified reference materials (CRMs) for geochemistry. The deviation of the biggest Kβ/Kα values relative to the smallest ones for the same element was from 1.52% (Si) to 20.98% (Al) when pressed pellets were used. The relative deviation of Kβ/Kα values for Ca was as high as 3.56% even for two soil CRMs (GBW07404 and GBW07408). X‐ray diffraction analysis confirmed that the Ca elements in the two CRMs were in distinct phases, thereby leading to the different Kβ/Kα values. The Fundamental Parameter Method (FPM) results of two calibration strategies were compared. When one of the 14 CRMs was selected as unknown sample whereas the other 13 CRMs were used for calibration to determine Al2O3, SiO2, CaO, and Fe2O3, the relative errors were 10.80%, 8.77%, 8.33%, and 10.91%, respectively. Another strategy, where only one CRM was used for calibration of samples with large errors, was adopted by matching Kβ/Kα values. The results of calibrating using CRM with similar Kβ/Kα values were more accurate than those with different Kβ/Kα values.

The investigation of K-shell fluorescence parameters of Zn-Fe alloys with different grain size and microstrain values

It is known that zinc alloys with iron group metals have better corrosion resistance than pure zinc. Owing to the corrosion resistance of these alloys, Zn-Fe coatings are widely used in automotive industry and have excellent mechanical performance. In this work, we investigated the relationship between the changes in the measured X-ray fluorescence parameters (K β /K α , σ Kα and σ Kβ ) and the changes in the structural parameters such as microstrain or grain size values for Zn-Fe alloys that were prepared with different pH values. To explain these changes, the K α and K β X-ray production cross sections, and the K β /K α X-ray intensity ratio values were calculated by three different ways for the elemental forms of Zn and Fe. The structural parameters, such as microstrain and grain size, were also calculated. We expect that the outer shell electronic distribution affects the structural parameters of the produced Zn-Fe alloys, changing the measured K α and K β X-ray production cross sections, and the K β /K α X-ray intensity ratio values. We also show that Zn-Fe alloy mi nimum microstrain value corresponds to the maximum changes in K β X-ray production cross-section values of Fe and Zn.
