“…(1). This relation describes ion-exchange chromatographic retention behaviors of various ions rather well, and has been extensively used to study, predict, and optimize ionexchange chromatographic separation [22][23][24][25][26] , albeit the problems involved in Eq. (2) have been repeatedly pointed out.…”

Electrostatic potential is responsible for various phenomena, particularly for the behaviors of ionic species in solution and at various interfaces. In some modes of chromatography, electrostatic interaction often governs overall retention selectivity; ion-exchange chromatography is a typical example. Thus, though the understanding of electrostatic interaction is essential to interpret and predict chromatographic retention in some cases, sufficient attention has not been paid to its roles. There are some possible reasons for this situation: (1) direct estimation of the potential is usually difficult; (2) simple models not involving the contribution from electrostatic potential have given rather good explanations to experimental data. Some research groups have recently attempted to take electrostatic potential effects into consideration in various ways, and have successfully developed chromatographic models. These approaches are expected to facilitate understanding of chromatographic phenomena dominantly controlled by electrostatic interaction and to provide a view of more physical significance. In this review, the author mentions advantages of chromatographic models based on electrostatic theory over usual separated-phase models, and shows problems to be solved.

“…In singlecolumn IC, the use of a poly(methyl methacrylate)-based anionexchange stationary phase dominates. Although favorable chromatographic performance has been demonstrated with very strong eluents such as naphthalenetrisulfonate (10), the most common eluents used in singlecolumn IC are phthalate or borategluconate.…”

Much of the practice of ion chromatography (IC) today is well-established science transformed into easily practiced technology; little art remains. Since it was first described in 1975 (1), IC has matured rapidly. The number of articles on IC published in Analytical Chemistry reached a peak in the mid-1980s. Nonetheless, judging by the number of articles abstracted by Chemical Abstracts, IC is increasingly being applied to a wide variety of areas, U.S. manufacturers of IC instrumentation indicate that, despite the recession, worldwide sales of IC instrumentation are on the rise.The reliability of IC is often taken for granted. The technique has become a routine tool for process analysis and control, notably for trace analysis in the nuclear power and semiconductor industries. IC has become so widespread that details such as modifications of vendor-supplied software and merits of vendor service contracts have been published in peer-reviewed literature (.2).Currently there are not many vendors of IC columns, especially as compared with the large number of vendors for LC columns.

“…19 We have also separated organic anions such as lactate, maléate, and tartrate with NDS17 and the bulky sulfur oxide anions such dithionate, tetrathionate, and other polythionates with NTS. 16 We report here simple chromatographic methods for the determination of C6-C12 aliphatic sulfonates and sulfates using sodium naphthalenedisulfonate-acetonitrile as the mobile phase on a novel polymeric fluorocarbon-amine cross-linked weak anion exchange silica column with either indirect conductivity or photometric detection modes. Indirect conductivity has not been explored previously for the detection of surfactants.…”

Naphthalenedlsulfon ate-acetonitrile as a mobHe phase alone with a crow United amine-fluorocarbon polymer suca column has shown to be an effective combination tor the separation of aliphatic anionic surfactants. Indirect conductivity and photometric detection modes are used to monitor these analytes. The retention of these surfactants Is found to depend on both the Ionic strength and the organic solvent content of the moMe phase. The mechanism of retention Is believed to be a combination of both reversed phase and Ion exchange processes. Selective separation of both C,-C12 alkanesulfonates and alkyl sulfates can be achieved In less than 9 min. Detection limits are as low as 5 ng for most analytes, with linear responses extending from at least 500 ppm to the sub-ppm level.
