Microbeam analysis—Selected instrumental performance parameters for the specification and checking of energy-dispersive X-ray spectrometers(EDS)for use with a scanning electron microscope (SEM)or an electron probe microanalyser(EPMA)
Standard in brief
Scope of Application:
本文件规定了以半导体探测器、前置放大器和信号处理系统为基本构成的X射线能谱仪最重要的特性参数。
本文件仅适用于使用基于固态电离原理的半导体探测器能谱仪。
本文件规定了与扫描电子显微镜(SEM)或电子探针显微分析仪(EPMA)联用的此类能谱仪性能参数的最低要求及核查方法。用于能谱分析的程序,已由ISO 22309[2]和ASTM E1508[3]规范,不在本文件范围之内。
