ASTM E1621
ASTM E1621 is a standard guide for elemental analysis using wavelength dispersive X-ray fluorescence spectrometry (WDXRF). It provides guidelines for developing and describing analytical procedures for determining the chemical composition of solid metals, ores, and related materials using this technique.
Here’s a breakdown of the key points about ASTM E1621:
Purpose:
- To ensure accurate and precise determination of metallic and non-metallic elements in various materials.
- To provide standardized protocols and reporting formats for WDXRF analysis.
Benefits:
- Improved data quality and consistency: Ensures reliable results across different laboratories and analysts.
- Facilitates communication and data sharing: Standardizes reporting formats for easier interpretation and comparison of results.
- Supports quality control and improvement: Outlines best practices for optimizing analytical procedures and minimizing errors.
Key aspects of the standard:
- Covers information that should be included in an X-ray spectrometric analytical method, such as:
- Instrument parameters and calibration procedures.
- Sample preparation techniques.
- Data acquisition and analysis methods.
- Quality control and validation criteria.
- Reporting requirements.
- Provides guidance on determining the optimum conditions for achieving acceptable accuracy for specific elements and materials.
