PBS-73
Pulverised Iron Ore goethite-hematite, oxide spiked, 1kg jar
PBS-73 is a certified reference material (CRM) manufactured from iron ore, prepared and certified in accordance with ISO 11459 and ISO Guide 35. Designed for quality control (QC) of chemical analysis, this CRM ensures accuracy and traceability in iron ore laboratories, particularly for materials with elevated LOI (Loss on Ignition) values.
Key Features
- Certified concentrations for major elements and trace components.
- High LOI values (up to 8.36% at 1000°C), ideal for labs analyzing hydrated iron ores.
- Produced via multi-stage crushing, milling (target p95@53µm), and homogenisation.
- Supplied in 1kg press-sealed plastic jars, with 10g sachets available upon request for blind laboratory submissions.
- Stable under normal storage conditions in sealed packaging.
