Analytical Spectroscopy and Sensors Group
The “Analytical Spectroscopy and Sensors” (GEAS) research group was established in 1982 by the Department of Analytical Chemistry of the University of Zaragoza.
It has been part of the Area of Chemical Science and Technology of the Institute of Research into Environmental Sciences of Aragon of the University of Zaragoza (IUCA) since its foundation in 2008.

Who we are
We are a Reference Research Group recognized by the Government of Aragon and the University of Zaragoza (E29_26R). The Group is part of the NanoBIOEnviron Action Group of the Iberus International Campus of International Excellence formed by the Universities of La Rioja, Lleida, Pública de Navarra and Zaragoza.
The group was a pioneer in nanomaterial characterization and conducts research in spectroscopic techniques, primarily inductively coupled plasma mass spectrometry (ICP-MS). It has made significant contributions to the theoretical and methodological development of single-particle ICP-MS (SP-ICP-MS).
The group also has expertise in separation techniques, such as asymmetric flow field-flow fractionation (AF4) and hydrodynamic chromatography (HDC), coupled with different detectors (ICP-MS, dynamic light scattering (DLS), and UV–Vis spectroscopy) for the detection and characterization of nanomaterials, microplastics, and nanoplastics.
