Inorganic reference standards

Achieve the most precise and accurate analytical results

When you can’t afford to leave anything to chance and need the purest and most accurate inorganic calibration standards and reference materials, you can be confident that our range of inorganic reference standards will provide the precision and accuracy that you need.

Our standards are used around the world in industrial and manufacturing QC, chemical production, power production, pharmaceutical and environmental labs to measure and deliver the quality of products and processes.


We start from the highest purity compounds, high purity acids and 18Mohm deionised water to prepare our VHG range of aqueous standards to make sure that your lab achieves the level of precision and accuracy that’s demanded.

Quality and traceability

Our standards are manufactured under ISO Guide 34 accreditation, and assayed following the NIST High Performance ICP-AES protocol. Each standard undergoes rigorous QA checks prior to shipment, and is accompanied by a Certificate of Analysis showing traceability to the SI.


If you have questions or need technical support, you can contact our highly trained teams who will meet you with technical expertise and aim to offer the best solution – commercial or technical - to resolve your enquiry.
