We manufacture in large batch sizes because we know that it is important for you to be able to access the same CRM over a long period of time. Our high stock levels mean you don’t have to be constantly changing grades or batches, giving you long term quality control over your laboratory process.

Let us know your typical monthly usage, and we will set aside material for you.

Homogeneity is an important property of all certified reference materials (CRMs). Homogeneity refers to the degree to which the composition and properties of a sample are uniform throughout the batch.

Pulverised CRMs are also homogeneous within each jar so that the contribution of sampling error is negligible. At IM Standards, homogeneity is a top priority, and we measure and report the uncertainty contribution of homogeneity for every jar and every batch before it is fully characterised and released to the market.

It is important for you to trust the property values for certified reference materials (CRMs) held in storage after they are manufactured. Stability refers to the ability of a material to maintain its chemical and physical properties over a specific period of time.

We monitor our product over time to ensure that the product does not change. While many mineral CRMs are very stable, we also provide you with guidelines on how to store and use our CRMs to maintain their trustworthiness.

Particle size distribution is an important aspect of certified reference materials (CRMs) as it can affect the sampling error and the accuracy and precision of analytical results.

Our particle size distributions are designed to match the target for routine prepared samples in the laboratory.  We ensure that homogeneity is maximised, and erroneous handling effects are minimised.

Our Pulverised Gold Certified Reference Materials (CRMs) are a manufactured product to a high specification:

• High quality raw materials are used and products are designed specifically for the application.
• Manufactured standards can be a more effective product for laboratory QC and when resolving quality issues with methods and analysis.
• A variety of controlled matrices available – oxide and sulphide based.
• The manufacturing process provides us with the ability to control our product quality with high precision – there is a specific intent in our batch chemistry.
• IM Standards can manufacture matrix matched CRMs from ore supplied on demand.

Think of us as your proactive CRM partner. Our CRM certificates should provide you with all the information you need.  If you need us, we are here to help you interpret your CRM data.

We also hold a library of samples of all our products. This makes traceability extremely easy and facilitates any troubleshooting and problem-solving you may need our assistance with.
