The IGME General Laboratories are a unit that provides specialized technical services. It provides experimental technical data supporting the research projects of the Organism itself and other Organisms and Entities, both public and private, testing a wide range of samples related to earth sciences, such as rocks, drilling cores, soils, sediments, water and leachate. The capacity to carry out analysis and testing covers the entire process, from the initial preparations
of the different materials to their analysis or testing by other high precision and accuracy techniques required to identify and quantify essential elements in evaluating resources.

Other services provided include the management of laboratory equipment and instruments, technical advice on instruments, equipment and tested materials, support for the training of laboratory technical personnel through the provision of practices and waste management following current regulations.

Its headquarters are placed in Tres Cantos (Madrid). According to the organization chart, it is divided into four laboratories (Water, Geochemistry, Minerallurgy, and Technological Tests and Natural Stone) and an Applied Microscopy/Artificial Vision Unit, which are independent but complementary to each other and act in a coordinated manner.

The Laboratories have established a Quality Management System based on the requirements of the UNE-EN ISO/IEC 17025 Standard, managed through an application (SILAB) developed by the Area of Geoscientific Information Systems and Institutional Databases of the IGME itself, which promotes the organization and management of work in a computerized way. IGME General Laboratories are part of the Network of Laboratories of the Community of  Madrid (RedLab 192) and have an ENAC accreditation to conduct physicochemical analysis of natural mineral waters, spring waters, mineral-medicinal waters, mineral-industrial and thermal waters.

To guarantee the quality of the analysis and test results, the General Laboratories participate in interlaboratory intercomparison tests, such as the AQUACHECK program on water samples, organized by LGC Standards, or those organized by the International Association of Geoanalysts (IAG) on solid samples.
