Inverse liquid chromatography in surface characteristic of materials
Katarzyna Adamska, Karol Kadlec and Adam Voelkel
Poznan University of Technology, Poland
Examination of the physicochemical properties of different materials is important for their adsorptive or adhesive
characteristics. Inverse Liquid Chromatography (ILC) technique differs from among generally known chromatographic
methods, that it is not related to the separation of components of mixtures, but the interaction of test compounds with the
investigated material, constituting the stationary phase of chromatography column. Interactions between the material and
the test compounds affect the measured retention parameters and the shape of chromatographic peaks. Application of ILC
seems to be useful to direct study of solid-liquid interactions in real conditions, which include: pressure, temperature and pH.
This technique, in conjunction with proper mathematical models, allows evaluating the physicochemical characteristic of the
biomaterials surface: its ability to various types of intermolecular interactions (e.g. capacity to donor-acceptor interactions),
assessment of the impact of the number and type of functional groups on the surface activity. ILC can be also applied to
characterize materials used in a separation process - mesoporous aluminosilicates (zeolites) for e.g. their ability to adsorption.
The characteristic of the surface layer of such materials allows the analysis of the influence of the respective modifier’s ligand
for adsorption or separation processes. ILC technique thus allows the detailed characterization of the surface, taking into
account its ability to various types of intermolecular interactions. This knowledge is essential for an appropriate development
and improvement of different solid materials.
Biography
Katarzyna Adamska graduated at Wroclaw University of Technology at Faculty of Chemistry in 1999. In 2002, she started PhD studies at Poznan University of
Technology in Institute of Chemical Technology and Engineering. In 2007, she got the academic degree of Doctor. Her PhD thesis entitled “Determination of the
solubility parameter and its components for materials used in the pharmaceutical industry” was related, mainly, to the use of inverse gas chromatography in studies
of different excipients, applied in pharmaceutical formulations.
