PBS-75
Pulverised Bauxite, 1kg jar
PBS-75 is a pulverised bauxite certified reference material (CRM), certified in accordance with ISO Guide 35:2017 and ISO 17034:2016. This CRM is specifically designed for quality control (QC) of XRF and TGA analysis in bauxite processing.
Key Features
- Certified concentrations for major components and trace elements.
- Moderate LOI (15.22%), reflecting gibbsite/boehmite content.
- Produced via multi-stage crushing, pulverisation (≤53µm), and homogenisation for exceptional uniformity.
- Supplied in 1kg press-sealed plastic jars, with 10g sachets available upon request for blind laboratory submissions.
- Stable for 10 years when stored sealed under normal conditions.
