Scope
本文件提供了采用辉光放电发射光谱法(Glow discharge optical emission spectrometry,以下简称GDOES,)进行深度剖析和体相分析的指南。本文件仅限于讨论刚性固体样品的分析,不包括粉末、气体或溶液的分析。结合现有和将来特定的标准方法,本文件旨在能够实现仪器的规范管理和测量条件的控制。尽管近年来有不同类型的辉光放电发射光源问世,但目前绝大多数使用直流和射频光源的辉光放电光谱设备仍以空心阳极的Grimm型为主。然而不同于最初Grimm型光源阴极接触样品正面的设计,一些光源的阴极接触常置于样品背面,例如Marcus型光源。本文件包含的条款同样适用于上述 2种和其他类型的光源,Grimm型光源仅作为一个实例。
