PBS-310
Pulverised sediments and low grade BIF, 1kg jar
PBS-310 is a certified reference material (CRM) prepared from pulverised sediments and low-grade banded iron formation (BIF) sourced from the Pilbara region of Western Australia. Spiked with elevated levels of NaCl and Ca, this CRM is designed for laboratories performing XRF fusion and TGA (LOI) analysis. It was prepared and certified in accordance with ISO 17034:2016 and ISO Guide 35:2017, ensuring reliable performance in quality control and validation applications.
Key Features
- Certified for major and minor oxides in sediment-hosted BIF material.
- Produced by multi-stage drying, pulverising, and homogenisation to ensure excellent uniformity.
- Certified through an inter-laboratory study involving multiple ISO 17025-accredited laboratories.
- Supplied in 1kg press-sealed plastic jars, with 10g sachets available upon request for blind laboratory submissions.
- Stable under ambient storage conditions with a 10-year certificate validity.
