标准摘要
[中文适用范围]： 本文件提供了在电子探针微量分析仪 (EPMA) 上执行常规诊断和质量保证程序的指南。 它旨在由仪器操作员定期使用，以确认仪器性能是否最佳，如果性能不佳，则可帮助排除故障。 它涵盖了独立测试和全面评估 EPMA 系统主要组件功能所需的参考材料的特性以及必要的分析程序。 本文描述的分析程序与单元件诊断程序不同，单元件诊断程序可以更快地执行。 此类程序对于执行测试的衍射器位置和条件是有效的，而本文描述的程序旨在鉴定仪器对未知物进行探索性分析、迹线分析和非常规工作（例如峰值干扰）的能力。 本文件适用于 EPMA 和其他波长色散光谱仪 (WDS) 系统，其中通过分析波长色散 X 射线光谱中观察到的特征 X 射线线的能量和强度来进行元素识别和定量。 它并不直接适用于使用能量色散光谱 (EDS) 的元素分析。 [外文原描述]： This document provides guidelines for performing routine diagnostics and quality assurance procedures on electron probe microanalysers (EPMA). It is intended to be used periodically by an instrument's operator to confirm that the instrument is performing optimally, and to aid in troubleshooting if it is not. It covers the properties of reference materials required and the analysis procedures necessary to independently test and fully evaluate the functionality of the main components of an EPMA system. The analytical procedure described herein is distinct from single-element diagnostic procedures, which can be performed more rapidly. Such procedures are valid for the diffractor position and conditions under which the test is performed, whereas the procedure described herein is intended to qualify an instrument's capabilities for exploratory analysis of unknowns, trace analysis and non-routine work (such as peak interferences). This document is applicable to EPMA and other wavelength dispersive spectrometer (WDS) systems in which elemental identification and quantification are performed by analysis of the energy and intensity of the characteristic X-ray lines observed in wavelength-dispersed X-ray spectra. It is not directly applicable to elemental analysis using energy dispersive spectrometry (EDS).
