“…This effect was termed "polar retention effect on graphite" (PREG). Exploiting this phenomenon, separations of very polar analytes, even of inorganic ions can be accomplished on this material [3]. Hence, PGC proved especially useful for analysis of very polar molecules, which are not, or only poorly retained in reversed-phase chromatography, e.g.…”

“…The electronic mechanism would involve specifically donor-acceptor (charge transfer) interaction and direct π electron overlap [26]. An ion exchange mechanism would also be possible on unmodified PGC for common anions separation [27]. Mobile phases containing perfluoroalkyl carboxylic acids were recently found to efficiently separate amino acids [23] and also seleno amino acids [13,28].…”

The retention of organic selenium compounds on a porous graphitic carbon stationary phase was investigated. Different acids were studied as mobile phases to elute selenocystamine, selenoethionine, selenomethionine and selenocystine. Detection was achieved using inductively coupled plasma-atomic emission spectrometry to provide selenium-specific and sensitive detection. The separation of the four species was carried out using methanoic acid. An important on-column preconcentration was obtained when solutes were injected in nitric acid or trifluoroacetic acid (TFA) media. The large injection volume employed (2,500 micro L) allowed us to reach low relative detection limits (2-6 micro g/L). The method, employing TFA as injection solvent and methanoic acid as the eluent was found to be robust with respect to different matrices spiked with selenocompounds.

This review is written as a privilege of the work of Professor Mietek Jaroniec on surface phenomena, adsorption, chromatographic separations, chemistry of conventional and ordered nanoporous materials.The problems of the porous graphitic carbon (PGC) application in analytical field are presented. Special attention is paid on possibilities of use PGC as a specific sorbent and packing material for selective isolation and analytes enrichment from complex matrices by means of liquid-solid extraction techniques (SPE, SPME, MSPD) and as particular stationary phase in analytical chromatographic columns. Surface and adsorption properties as well as a unique mechanism of retention on porous graphitized carbon sorbents are described. As supplement the examples of application in biomedical and environmental area are added.
