GB/T 16597-2019 (English Version) PDF

Scope: This standard specifies the general requirements for quantitative analysis of elements using X-ray fluorescence spectrometry, including terms and definitions, basic principles, instruments, reagents and materials, sample preparation methods, quantitative analysis, safety precautions and recording of measurement results. Expression. This standard is applicable to wavelength-dispersive and energy-dispersive X-ray fluorescence spectrometers for measuring elemental composition and element content in various materials. It can be used to measure all elements from 4Be to 92U in the periodic table except H, He, and Li. Qualitative and quantitative analysis of constant and trace amounts, for use in wavelength-dispersive and energy-dispersive X-ray fluorescence spectrometers using X-ray tubes as excitation sources. Mass fraction range of analyzed elements: 0.0001%~100%.
