石墨晶体预衍射X射线荧光分析仪是本单位自行研制的后处理控制分析专用设备,比常规的能量色散X射线荧光多1个石墨衍射器,以排除样品本身放射性的影响,因此,该设备可用于后处理高放废液中U、Np以及部分裂片元素的测量。在例行分析中,通常先建立工作曲线,在以后的测量中不必再测量标准。仪器本身每天都在变化,使工作曲线发生偏离,因此,有必要进行 Graphite crystal pre-diffraction X-ray fluorescence analyzer is self-developed post-processing control analysis of special equipment, energy dispersive X-ray fluorescence than conventional more than 1 graphite diffractometer to exclude the radioactive impact of the sample itself, therefore, the device is available Determination of U, Np, and some elemental lobes in post-treatment high-level liquid waste. In routine analysis, the working curve is usually established first, and it is unnecessary to measure the standard in subsequent measurements. The instrument itself is changing every day, leaving the working curve deviated, therefore, it is necessary
