Application of x-ray fluorescence spectrometry in the detection of small-sized high-temperature alloys for blasting equipment in xiaoliugou tungsten mine

This study investigates the application of X-ray fluorescence spectroscopy (XRF) analysis technology in the detection of small-sized high-temperature alloys in the blasting equipment of the Xiaoliugou tungsten mine. Using an Axios mAX wavelength dispersive X-ray fluorescence spectrometer, high-sensitivity detection of major and trace elements in high-temperature alloys was achieved by optimizing the experimental parameters (e.g., X-ray tube voltage, current, and detection time). The parameter optimization experiments for the high-temperature alloy standard material GBW01655 showed that the optimal X-ray tube voltage was 60 kV, the current was 50 mA, and the detection time was 30 seconds. The limit of detection (LOD) and limit of quantification (LOQ) of each element were calculated by several measurements on blank samples, and the results showed that they meet the demand for trace component detection of high-temperature alloys. In addition, the repeat test using the GH4738-1# standard sample verified the precision and accuracy of the method. Comparison of the actual sample analysis results with inductively coupled plasma mass spectrometry (ICP-MS) demonstrates the validity and reliability of the XRF method for on-site rapid detection.
