Course objectives
Speciation analysis is method of identification and determination of various chemical forms of certain elements in solution and solid samples or determination of its topological location there. The species can be considered as elements in oxidation state, organometalic compounds and complexes bound in various phases of the system (e.g. in soils), with bioligands (peptides, polysaccharides) and biological systems of organized structure (organelles, biomembranes, cells). Toxic and favour action of elements depends on biological, physical and chemical properties of the compounds species having the information about bioavailability of relevant metals and metaloids. Chemical, biological and toxicological properties of elements occurring as the species have impact into various field of daily life: risk assessment in environment; ecotoxicology; food industry; health and hygiene in work process; clinical chemistry and medicine; industrial analysis. Speciation analysis for determination of chemical forms of elements in solution and extracts obtained from solid samples are mostly realized by tandem techniques based on combination of on-line joining of high-efficient separation technique followed by specific element detection. Elemental speciation in solution can be also measured using electrochemical techniques, biosensors and radioanalytical methods. Topological speciation is based on application of probe measuring the interaction of focused photon or ion beam with matter.
