Speciation in analytical identification of one or more existing forms of elements determined by isotopic composition, oxidation state, complex or macromolecular structure.
Chemical species in trace range, toxic and essential species, bioavailability and toxicity of species.
Structural aspects of speciation (isotopic composition (Pb,O,N,C), electronic and oxidation states (As,Cr,Fe,Mn,V), inorganic compounds and their complexes(Al,Ni), speciation of organic (As,Sb,Se,Sn,Hg),) and macromolecular compounds (Cd, Fe, Co, Pt).
Methodology of speciation analysis. Sampling, preparation and measurement of species in air, water and biological samples.
Coupled systems in speciation (LC-ICP-MS, GC-ICP-MS, FFF-ICP-MS, CE-ICP, LC-ESI-MS).
Fractionation analysis methods. Dynamic aspects of speciation analysis.
