IMS-516
IMS-516 is a certified reference material (CRM) manufactured from lithium ore process tailings of LCT-type pegmatite origin. Prepared and certified in accordance with ISO 17034:2016 and ISO 33405:2024, this CRM is specifically designed for quality control in the analysis of processed lithium ores and tailings in geochemical and mining laboratories.
Key Features
- Unique Matrix: Certified for lithium ore process tailings, providing a vital quality control standard for processing and environmental monitoring.
- Certified for multiple techniques: Provides certified values for analysis via Lithium Borate fusion XRF, Na-Peroxide fusion ICP-MS/ICP-OES, and 4-acid digest ICP-MS/ICP-OES.
- Comprehensive characterisation: Certified through an extensive inter-laboratory program featuring up to 13 independent ISO/IEC 17025 accredited laboratories.
- Excellent homogeneity: Produced via multi-stage crushing, pulverisation (P95 @ 53µm), and homogenisation.
- Packaging: Supplied in press-sealed plastic jars.
- Stability: Stable under normal storage conditions, with a 10-year certificate validity.

Intended Use
This pulverised reference material is intended for monitoring and testing the accuracy and precision of analytical methods for lithium ore tailings, specifically:
- Fusion XRF for major oxides.
- Na-Peroxide fusion digest followed by ICP-MS / ICP-OES analysis.
- 4-acid digest followed by ICP-OES analysis.
It is recommended for deriving control charts and detecting methodological bias in routine laboratory quality control, especially relevant for processing plants and environmental assessment.
