标准范围

本文件提供了适用于批量和深度剖面GD-OES分析的指南。本文讨论的指南仅限于刚性固体的分析，不包括粉末、气体或溶液的分析。结合目前和未来可用的具体标准方法，这些指南旨在实现仪器的监管和测量条件的控制。尽管多年来已经开发了几种类型的辉光放电光发射源，但带空心阳极的格林型辉光放电光发射装置占了目前用于直流和射频源的辉光放电光发射装置的绝大多数。然而，阴极触点通常位于样品的背面，例如Marcus型源，而不是原始Grimm设计中的正面。本文包含的指南同样适用于和其他震源设计，格林型震源仅用作示例。

This document provides guidelines that are applicable to bulk and depth profiling GD-OES analyses. The guidelines discussed herein are limited to the analysis of rigid solids, and do not cover the analysis of powders, gases or solutions. Combined with specific standard methods which are available now and, in the future, these guidelines are intended to enable the regulation of instruments and the control of measuring conditions.Although several types of glow discharge optical emission sources have been developed over the years, the Grimm type with a hollow anode accounts for a very large majority of glow discharge optical emission devices currently in use both for dc and rf sources. However, the cathode contact is often located at the back of the sample, in e.g. the Marcus type source, rather than at the front as in the original Grimm design. The guidelines contained herein are equally applicable to both and other source designs and the Grimm type source is used only as an example.
