• Chromatography - the separation technique of the 20th century; Mikhail Semenovich Tswett - the father of modern chromatography; from crushed bricks to microchips; thin layer chromatography; from thin layer chromatography to high performance thin layer chromatography to planar chromatography; the way it was; gas chromatography - a personal retrospective; the evolution of capillary column gas chromatography - a historical overview; forty years of gas chromatography; liquid crystals stationary phases in gas chromatography - a historical prospective; quantitative retention-eluent composition relationships in partition and adsorption chromatography; hollow sticks with mud inside - the technology of HPLC columns; on the way to a general theory of gradient elution; solvent selection for optimal separation in liquid chromatography; my life in separation sciences - study of separation mechanisms.
