Advances in evolved gas analysis (EGA) techniques are periodically reported by our group to provide useful examples of their applications in many different fields. It is actually recognized that anytime is requested a correct interpretation of the thermally induced reaction mechanism, involving the formation of gaseous species, it is strongly recommended the characterization of the evolved products.
Speciation studies are based on fundamental models that relate the properties of biomimetic coordination compounds to the stability of the complexes. In addition to the classic approach based on solution studies, solid state properties have been recently proposed as supporting tools to understand the bioavailability of the involved metal. A ten-year long systematic study of several different complexes of imidazole substituted ligands with transition metal ions led our group to the definition of a model based on experimental evidences.
