X 射线荧光光谱有波长色散和能量色散之分,波长色散又有顺序式和多道谱仅两类,顺序式适用科研及多用途的工作,多道谱仪则适用于定型或批试样分析。目前这种方法已广泛应用于冶金,地质、化工、环保、生物等领域,当前世界上正在使用的波长色散 X 射线荧光光谱仪(以下简称 XRFS)已有一万台之多,可以说 XRFS 已是实验室不可缺少的分析仪器。其主要原因是它不仅能提供从碳到铀的全部元素的定性、定量分析,进行定量分析时不仅可分析高达100%的含量,且对大多数元素不要浓缩即可测定试样中 ppm 级的元素,其测量精度已高达0.05%,这是其它原子光谱仪器所不能比的。基于新的 XRFS 在制造
X-ray fluorescence spectroscopy with wavelength dispersion and energy dispersion of the points, the wavelength dispersion and sequential and multi-channel only two categories, the sequential application of scientific research and multi-purpose work, multi-channel spectrometer is suitable for stereotypes or batch sample analysis . At present, this method has been widely used in metallurgy, geology, chemical industry, environmental protection, biology and other fields. Currently, as many as 10,000 sets of wavelength-dispersive X-ray fluorescence spectrometers (XRFS) are being used in the world. It can be said that XRFS has been Laboratory indispensable analytical instruments. The main reason is that it not only provides qualitative and quantitative analysis of all the elements from carbon to uranium, not only can analyze up to 100% of the content in quantitative analysis, but also can measure the ppm level of the sample Element, the measurement accuracy has been as high as 0.05%, which is not comparable to other atomic spectrometer. Based on the new XRFS in manufacturing
