GB/T 13748.23-2024 "Methods for chemical analysis of mg and magnesium alloys, Part 23: Determination of element content, wavelength dispersion X-ray fluorescence spectrometry" stipulates the use of X-ray fluorescence spectrometry (XRF) to determine the content of aluminum, zinc, manganese, silicon, iron, copper, titanium, strontium, nickel, lead, zirconium, gadolinium, yttrium, cerium, neodymium and other elements in mg and magnesium alloys. The method can determine multiple elements simultaneously, and has the advantages of avoiding cross-contamination without cleaning. The determination process is fast and accurate. The steps of instrumentation, sample processing, calibration Linear dispersion establishment and data processing are described in detail in the standard to ensure the precision and accuracy of the analysis results. Through the application of this method, the production, trade and quality control of magnesium alloys can be effectively supported to meet the needs of the industry for elemental analysis.
