IMS-103
IMS-103 is a quantitative X-ray Diffraction pulverised iron ore reference material, sourced from Pilbara region iron ores in Western Australia and certified in accordance with ISO Guide 35:2017 and ISO 17034:2016. This CRM is specifically designed for quality control of QXRD analysis, featuring a hematite-goethite dominant composition with certified amorphous content. This CRM is ideal for metallurgical and mineral processing applications.
Key Features
- Certified mineralogical concentrations via QXRD, including amorphous content and iron ores key minerals such as goethite, hematite, kaolinite and quartz.
- Two reporting formats: Values including amorphous content and normalized to crystalline-only basis.
- Produced via multi-stage pulverisation and air classification (p50: 4µm)
- Supplied in 100g press-sealed plastic jars, with 10g sachets available upon request for blind laboratory submissions.
- Stable for 10 years when stored sealed under normal conditions.
