Matrix reference materials

We produce and sell matrix reference materials for organic and elemental analysis. Matrix reference materials are used for method validation and quality control.

Our reference materials

NMI reference materials

Our reference materials have demonstrated homogeneity and stability. We take all care in storing and handling these materials.

We supply reference materials with product information and safety data sheets. We’ll provide the currently valid certification where we can.

Our reference materials are available globally through LGC Standards, our international partner.

Certified reference materials

We produce certified reference materials (CRMs) with established metrological traceability to the SI unit for mass (kg). We report all purity values, stated as a mass fraction, with the associated uncertainty in the certificate of analysis.

How to order reference materials

To order email us at chemref@measurement.gov.au or call us on 02 9449 0191.
