The EVISA database on Materials contains information about Certified Reference Materials (CRMs), standard materials (for identification of compounds or calibration), sorbents and reagents used within the framework of speciation analysis.

You can search for a name of the material (e.g. BCR-462), for a keyword in the description of the material (e.g. sediment, for a producer (e.g. IRMM), for a material type (CRM, Standard, Sorbent, Reagent, for the phase of the material (solid, liquid, powder) and for the analytes (element, species) it is specified for.
