Method development and validation for the identification and determination of trace elements (toxic and essential), organometallic compounds (including persistent organic pollutants) and radionuclides (low activity; long half-life) in matrices with high environmental impact like natural and industrial waste waters, biologic fluids, food/food supplements and others.
Focus on inorganic speciation analysis (e.g. speciation of As, Cr, Hg, Se) and some knowledge and experience in organic speciation analyses. Developed high accuracy methods based on liquid (HPLC, LC) and gas chromatography (GC), coupled to inorganic mass spectrometry and nanoparticles analysis by asymmetric flow-FFF coupled to UV/VIS, MALS and other detectors (e.g. for Fe and Se nanoparticles characterisation in waste waters, environmental colloids (fulvic, humic acids).
Previous experience with ESI-MS/MS for Se compounds identification with quadrupole ion-trap MS and in kinetic studies of inorganic reactions, species stability and transformations.
Currently working on the developing methods for the standardisation of Hg and Hg(II) reference gas generators by direct coupling to ICP-MS and via Thermal Desorption GC-ICP-MS by using SSIDMS.
