This guide covers procedures for quantifying the elemental composition of phases in a microstructure. It includes both methods that use standards as well as standardless methods, and it discusses the precision and accuracy that one can expect from the technique. The guide applies to EDS with a solid-state X-ray detector used on an SEM or EPMA.
WJE laboratories are accredited by ANAB (ISO/IEC 17025) to perform testing standard ASTM E1508 for Quantitative Analysis by Energy-Dispersive Spectroscopy.
