Abstract

This chapter (Principles and Practice of X-Ray Fluorescence Spectrometry – 2: Wavelength Dispersive and Energy Dispersive Instrumentation) is a contribution to the Geostandards and Geoanalytical Research Handbook of Rock and Mineral Analysis – an online textbook that is a fully revised and updated edition of A Handbook of Silicate Rock Analysis (P. J. Potts, 1987, Blackie, Glasgow).

Chapter 6, Part 2 (from Section 2 of the handbook devoted to techniques for the determination of major and trace elements) deals with XRF wavelength dispersive and energy dispersive spectrometry. Dealing first with WD-XRF, Part 2 discusses its instrumentation, spectrum analysis and routine operating conditions. The following sections on ED-XRF discuss its detectors and their characteristics, the associated (pulse-processing) electronics, and X-ray interaction with these detectors. Consideration is then given to procedures for ED-XRF spectra analysis, as well as its analysis of silicate rock and mineral materials under routine operating conditions. Further sections cover total reflection XRF (TRXRF) and field portable (PXRF) instrumentation, and statistical procedures relevant to XRF analysis. The chapter also includes a comparison of the WD and ED spectrometer types and of their analytical performance, with emphasis on silicate rock analysis.

岩石和矿物分析GGR手册第6章（第2部分）x射线荧光光谱法的原理和实践- 2：波长色散和能量色散仪器

本章（x射线荧光光谱法的原理和实践- 2：波长色散和能量色散仪器）是对岩石和矿物分析的地质标准和地质分析研究手册的贡献-这是一本在线教科书，是硅酸盐岩石分析手册（P. J. Potts, 1987, Blackie，格拉斯哥）的全面修订和更新版。第6章，第2部分（来自手册的第2节，专门用于测定主要和微量元素的技术）处理XRF波长色散和能量色散光谱。第2部分首先介绍了WD-XRF，讨论了它的仪器、频谱分析和日常工作条件。下面几节讨论ED-XRF的探测器及其特性，相关的（脉冲处理）电子学，以及与这些探测器的x射线相互作用。然后考虑ED-XRF光谱分析的程序，以及在常规操作条件下对硅酸盐岩石和矿物材料的分析。进一步的章节介绍了全反射XRF （TRXRF）和现场便携式（PXRF）仪器，以及与XRF分析相关的统计程序。本章还包括WD和ED光谱仪类型及其分析性能的比较，重点是硅酸盐岩石分析。
