What are Certified Reference Materials?
Certified reference materials (CRMs) are used to calibrate and verify the accuracy of chemical analyses in the mining industry. They play a vital role in Quality Assurance/Quality Control (QA/QC) programs for mineral exploration, mine development, and mineral processing.
CRMs are essentially control samples with known chemical compositions. They are inserted into batches of samples undergoing analysis to monitor the consistency and accuracy of the analytical results. This helps to ensure that the data obtained from the analysis of real samples is reliable and can be used for informed decision-making.
What are CrushedCRM™ Gold?
Crushed Gold CRMs are ~3mm rock chips specifically produced using our patent-pending, in-house manufacturing process.
Engineered specifically for large mass analytical methods like PhotonAssay™ and PAL, they are the only CRMs designed for these laboratory techniques. They are certified and matrix-matched to routine samples.
Quality control programs for laboratory analysis rely on treating certified reference materials (CRMs) identically to routine samples. Matching the physical and chemical characteristics, method of use, and handling in all laboratory processes for both CRMs and routine samples develop superior confidence in the results.
Pulverised CRMs have been used for PhotonAssay™ and PAL, but they behave adversely compared to crushed samples. To solve this issue, CrushedCRMs™ have been developed as the essential quality control material for these laboratory. methods.
Produced under our 17034 accreditation, we guarantee the inter-comparability of measurement results worldwide and the highest level of quality assurance that an accredited impartial manufacturer can obtain.
Do you produce in different batch sizes?
Our flexible system allows us to produce custom batches from small to 20 tonnes.
What is the difference between custom and catalogue CRMs?
Custom: We manufacture custom CRMs to the exact specifications of our clients. Catalogue: CRMs we hold pre-existing stock for and you can buy immediately based on specification.
We are the only company in the world with the ability to manufacture custom Crushed or Pulverised materials across different commodity classes.
Who are Pilbara Standards?
Pilbara Standards was the original name of IM Standards. Set up in 2012 it became the world’s leading supplier of iron ore certified reference materials.
In 2021 we rebranded to Independent Mineral Standards, to better reflect the growing breadth of our product range and our focus on certified reference materials across multiple commodities.
