IMS-475
Crushed Iron Ore, 2kg HDPE bag
IMS-475 is a crushed iron ore certified reference material (CRM), sourced from Solomon, Western Australia, and certified in accordance with ISO 33405:2024 and ISO 17034:2016. This CRM is specifically designed for quality control (QC) of sample preparation and XRF/TGA analysis, offering precise characterization of crushed iron ore materials with high iron content.
Key Features
- Certified concentrations for major elements (Fe, SiO₂, Al₂O₃) and trace components (P, Mn, LOI).
- High-iron content (61.03% Fe), ideal for crushed ore analysis.
- Produced via drying, crushing (≤5mm), and homogenisation for uniformity.
- Packaged in 2kg sealed plastic bags for bulk sample preparation.
- Stable for 10 years when stored in dry conditions.
