PBS-196
Crushed Iron Ore
PBS-196 is a certified reference material (CRM) manufactured from coarse iron ore sourced from an undisclosed site in Western Australia. Prepared and certified in accordance with ISO 11459 and ISO Guide 35, 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 elements and LOI values at multiple temperatures (371°C, 425°C, 650°C, 1000°C). Provisional and informational values for trace elements.
- Manufactured through multi-stage crushing, screening, and homogenization to ensure representativeness of coarse iron ore samples.
- Certified via 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 for accurate results.
