Axion Reference Materials are manufactured to ISO 17034:2016 and verified to ISO/IEC 17025:2017. The Certified Value is the manufactured concentration. The certified value is determined by high precision weighing of thoroughly characterized starting materials and secondarily verified by analytical measurement.
The starting materials used to prepare Axion Reference Materials are certified reference materials produced and certified in accordance with ISO/IEC 17025:2017 and ISO 17034:2016. When no such material is available, thoroughly characterized high purity raw materials with a documented purity are used. All balances and check weights used are calibrated by an ISO/IEC 17025 Calibration Laboratory, providing traceability of measurement to the SI.
Each product also undergoes thorough stability and homogeneity testing, ensuring every time our customers use our products, they can trust them to provide continuous quality throughout the entire shelf-life of the product.
The combination of all these efforts manifest in our product Certificate – a certificate that is not just a certificate of analysis, but our guarantee of the Certified Value.
