The National Technical Specification for the Production and Application of Standard Materials for Quantitative Analysis Using Electron Probe, designated as JJF 1029-2024, was officially released on January 1, 2024. This standard sets forth detailed guidelines for the development and production of reference materials specifically designed to ensure accuracy in quantitative analysis conducted via electron probe microanalysis (EPMA). It provides comprehensive technical requirements that encompass purity standards, homogeneity testing methods, stability assessment protocols, and packaging specifications.
The specification aims to enhance the reliability and consistency of EPMA results by standardizing procedures for preparing and certifying reference materials. This includes rigorous quality control measures to prevent contamination during production processes as well as precise determination methodologies for achieving high levels of accuracy in chemical composition measurement.
Furthermore, JJF 1029-2024 offers guidance on the selection criteria for appropriate matrix types and analytical techniques used alongside EPMA analysis. It also outlines necessary documentation requirements to facilitate traceability and verification purposes when deploying these reference materials across various scientific applications.
