MISSION
Su mission The primary objective is to strengthen the region's scientific and technological capabilities by offering postgraduate training for local professionals and addressing areas of expertise through the provision of highly complex analytical services and specialized consulting in the fields of environment, food, agriculture, industry, health, pharmaceuticals, and others. To address the challenges in these areas within the socio-productive sector, we maintain constant interdisciplinary collaboration with the research groups belonging to the platform.

VALUES

The institution bases its work on the values ​​of scientific excellence, commitment to the socio-productive environment, transparency and technical traceability, ethical rigor and multidisciplinary inter-institutional collaboration.

OBJECTIVES

Through state-of-the-art analytical equipment and a highly trained and constantly developing team, its central objectives focus on studying, monitoring and contributing to solving environmental challenges with a direct impact on health and quality of life; developing and validating customized analytical methodologies and standardized multi-residue protocols; promoting in vitro and ecotoxicological studies; and making advanced analytical capabilities available to the region that are difficult to access elsewhere.
