"We will investigate possibilities for rapid analytical separations in the conventional analytical columns, packed and monolithic capillary columns for HPLC and in capillary electrophoresis with modified inner walls. The rapid separation conditions will be used for multidimensional separations in orthogonal separation systems with the eventual aim of developing a comprehensive two-dimensional HPLC separations. To find suitable conditions for combining different phase systems, we will use our earlier acquired knowledge of the effects of the working conditions on the retention and separation selectivity. We will apply the two-dimensional separation conditions for the analysis of food samples, such as for full characterization of the constitution of various vegetable oils and for the detection, identification and determination of natural antioxidants in beverages and plant extracts, for the characterisation of complex surfactant samples of the type of block copolymers and of some synthetic dyes,"@en . . . . .
