A matrix reference material is defined as a reference material that contains major, minor, and trace components. Matrix materials are intended to be used alongside real sample analysis of the same or a similar matrix (ISO D GUIDE 30:2013(E) 2.4.). Reference matrix materials are primarily used as quality control standards in laboratories. The use of matrix reference materials in analytical processes provides practical examples of how to properly apply the selected standard materials in an analytical process, including method validation, verification, quality assurance, and quality control studies.

In this section, we offer a wide range of matrix material standards for food, environment, and other applications. These reference materials are collected from proficiency test rounds provided by ISO 17043 accredited institutes. The assigned value of the selected parameter is determined by calculating statistical data (for example, mean value, error, standard deviation, etc.) from the laboratories' results. Matrix material standards are also provided with a certificate of analysis (CoA) document that includes the exact assigned value, uncertainty value, storage conditions, shelf life information, etc.
