IMS-469
Pulverised Bauxite, 1kg jar
IMS-469 is a pulverised bauxite certified reference material (CRM), sourced from West African bauxite ores and certified in accordance with ISO 33405:2024 and ISO 17034:2016. This CRM is specifically designed for quality control (QC) of XRF, TGA, and caustic digestion analysis, featuring a high-alumina, low-silica composition ideal for alumina refining processes.
Key Features
- Certified concentrations for major and trace elements.
- Specialty certifications for reactive silica and available alumina
- Produced via multi-stage 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.
