Electronic training and methodological complex . Nizhny Novgorod: NSU, 2010. 91 s. The first part of the manual describes the basic concepts and classification of chromatographic methods. The terminology used in chromatography and the principles of ion separation in sorption processes. are presented. In addition, the characteristics of ion retention parameters, the selectivity and efficiency of the column, the resolution of chromatographic signals. are given. The second part of the manual is devoted to the basics of practical ion chromatography - one of the promising areas of modern instrumental analysis. The basics of purposeful selection of stationary and mobile phases, suppressing systems and detectors in ion chromatography. Much attention is paid to increasing selectivity and reducing the detection limits of various ions in environmental objects and technological environments.
