x-射线荧光法可以测定ppm到100％含量范围内从Na到U的所有元素,并具有不破坏样品、快速、多元素同时分析的特点。作为定量分析的手段已在地质、冶金、环境监测及材料科学等研究领域得到广泛应用。近年来,由于双晶x-射线荧光光谱仪的研制成功,在元素的存在状态研究方面又开辟了新的应用领域。尽管如此,在超微量分析、表 The x-ray fluorescence method measures all elements from Na to U in the ppm to 100% range and features fast, multi-element simultaneous analysis without breaking the sample. As a means of quantitative analysis has been widely used in the field of geology, metallurgy, environmental monitoring and material science research. In recent years, due to the successful development of the dual crystal x-ray fluorescence spectrometer, a new application field has been opened up in the study of the existence of elements. Nonetheless, in the ultramicro analysis, the table
