PBS-155
Crushed Iron Ore 2kg
PBS-155 is a certified reference material (CRM) manufactured from coarse iron ore composites sourced from multiple Australian sites. 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 on coarse iron ore samples.
Key Features
- Certified concentrations for major elements and trace elements.
- Produced via drying (105°C), crushing, and screening (5 mm) to ensure representativeness of coarse ore samples.
- Certified through a 10-laboratory round robin, including ISO 17025-accredited labs across Australia and Indonesia.
- Supplied in 2kg heat-sealed plastic bags with unique batch numbering for traceability.
- Stable under normal storage conditions; recommended drying at 105°C prior to analysis.
