IMS-548
Pulverised Iron Ore
IMS-548 is a pulverised iron ore Certified Reference Material (CRM) sourced from the Pilbara region of Western Australia and certified in accordance with ISO 17034:2016 and ISO 33405:2024. This CRM is specifically designed for quality control (QC) of XRF and TGA (LOI) analysis, providing certified values for major and trace elements commonly determined in iron ore testing. It is suitable for monitoring analytical accuracy and precision in both commercial and mine-site laboratories.
Key Features
- Certified concentrations for major analytes including Fe, SiO₂, Al₂O₃, together with minor and trace constituents such as TiO₂, Mn, CaO, P, S, MgO, K2O, Na₂O, As, Cu and Zn.
- High-grade iron ore with 65.14% Fe and low levels of gangue minerals, making it suitable for routine iron ore analysis.
- Produced using multi-stage pulverisation and homogenisation, with homogeneity verified in accordance with ISO 33405:2024.
- Supplied in 1kg press-sealed plastic jars, with 10g sachets available upon request for blind laboratory submissions.
- Stable under normal storage conditions when stored in a cool, dry environment and re-sealed after opening.
