ISO 16967 ICP Analysis of Rare Earth Elements in Materials
The ISO 16967 standard provides a robust framework for Inductively Coupled Plasma (ICP) analysis specifically designed to quantify rare earth elements (REEs) present in various materials. This method is essential for ensuring the accuracy and reliability of REE content, which is critical across numerous industrial sectors including electronics, automotive, aerospace, and advanced ceramics.
Rare Earth Elements are a group of 17 chemical elements characterized by their similar electronic structures that enable them to form compounds with various properties. The accurate quantification of these elements can be challenging due to their overlapping spectral lines in ICP analysis. The ISO 16967 protocol addresses this challenge through optimized sample preparation and instrumental settings.
Sample preparation involves the dissolution of solid materials into an acidic solution, ensuring that all REEs are uniformly distributed for accurate measurement. This method ensures that even trace amounts of REEs can be detected with high precision. The use of an ICP spectrometer allows for the simultaneous analysis of multiple elements within a single run.
The instrumental setup includes a high-resolution optical system capable of resolving closely spaced spectral lines, which is crucial for accurate quantification of overlapping lines. Calibration solutions are prepared using certified reference materials to ensure that the instrument's response accurately reflects real-world conditions.
Data analysis follows strict protocols outlined in ISO 16967, ensuring that results are consistent and comparable across different laboratories. The report includes detailed information on the sample preparation process, instrumental settings, calibration details, and the final quantitative results expressed as weight percentages of each REE present in the material.
| Parameter | Description |
