Matrix materials are intended to be used in conjunction with real sample analysis of the same or a similar matrix (ISO D GUIDE 30:2013(E) 2.4.). We manufacture all our standards at locations that are double accredited to ISO/IEC 17025, ISO Guide 34 and ISO 17034 – the highest achievable quality level for reference material manufacturers.
Drinking water testing is performed to ensure water quality for human consumption. Our drinking water matrix CRMs permit assessment of water source contamination levels and address problems for intended use. Wastewater testing is required by governments bodies to protect the environment and communities. We offer many products for the testing of wastewater from households, industrial wastewater from chemical, pharmaceutical, food and other production facilities.
We offer a range of soil matrix CRMs for testing of BNAs, PAHs, aroclors, PCB Congeners, nitroaromatics, dioxins, furans, hydrocarbons, pesticides, herbicides, volatile organic compounds (VOCs) and inorganic compounds. Along with soil matrix CRMs, we also offer environmental matrix CRMs to support environmental testing needs.
We have various food matrix reference standards to determine nutrient concentrations to facilitate compliance with nutritional labeling. Our portfolio of matrix reference materials includes CRMs from national metrological institutes, such as NIST, JRC, FAPAS and BAM.
