PBS-32 Iron Ore
Pulverised Iron Ore
PBS-32 is a certified reference material (CRM) manufactured from hematite-goethite iron ore sourced from the Pilbara region of Western Australia. Certified in accordance with ISO Guide 35:2006, this CRM is designed for rigorous quality control in laboratories performing XRF lithium-borate fusion and multi-temperature Loss on Ignition (LOI) analysis.
Key Features
- Certified concentrations for major and trace elements.
- Produced via drying (105°C), crushing, milling, and homogenization to ensure excellent homogeneity.
- Certified through a 12-laboratory round robin, including ISO 17025-accredited labs across Australia, Indonesia, and Canada.
- Supplied in 1kg press-sealed plastic jars, with 10g sachets available upon request for blind laboratory submissions.
- Stable under normal storage conditions; recommended drying at 105°C prior to analysis.
