Technological Offer
The GEAS research group offers a very wide range of possibilities for the analytical control of parameters and analytes in food, agricultural, environmental, water, plastics, metals and alloys, new materials, clinical parameters, etc …
The experience accumulated in almost forty years of working on OTRI contracts, the Company-University Foundation, and mixed innovation programs with private companies, together with the analytical instrumental techniques available in the GEAS laboratories, allow us to offer solid and reliable responses to practically all of the analytical problems that may arise, as well as advising on instrumental facilities and equipment for analytical laboratories.
