ISO 22309:2011 gives guidance on the quantitative analysis at specific points or areas of a specimen using energy-dispersive spectrometry (EDS) fitted to a scanning electron microscope or an electron probe microanalyser; any expression of amount, i.e. in terms of percent (mass fraction), as large/small or major/minor amounts is deemed to be quantitative. The correct identification of all elements present in the specimen is a necessary part of quantitative analysis and is therefore considered in ISO 22309. ISO 22309 provides guidance on the various approaches and is applicable to routine quantitative analysis of mass fractions down to 1 %, utilizing either reference materials or "standardless" procedures. It can be used with confidence for elements with atomic number Z > 10. Guidance on the analysis of light elements with Z
Abstract
Overview
ISO 22309:2011 - "Microbeam analysis - Quantitative analysis using energy‑dispersive spectrometry (EDS) for elements with an atomic number of 11 (Na) or above" - is an international guidance standard for performing and reporting quantitative X‑ray microanalysis using EDS on scanning electron microscopes (SEM) and electron probe microanalysers (EPMA). It covers procedures for point and area analyses, element identification, data reduction and reporting, and addresses both reference‑material and “standardless” approaches for routine quantitative analyses down to about 1 % mass fraction (with careful cases to 0.1 %).
Key technical topics and requirements
- Scope and element range: Designed for elements with atomic number Z ≥ 11 (Na) and above; guidance on light elements (Z
