“…The anionic exchange functionality was achieved by using γ-chloropropyl triethoxy silane, hexamethyl disilazane and N,N-dimethyl benzylamine, phenyl trichlorosilane, chlorosulfonic acid and hexamethyl disilazane were used to obtain the cationic exchange functionality. A good agreement with the results obtained with other conventional methods was confirmed [16]. Typical chromatograms of a sample are in the original publication presented in Figure 2.…”

This review focuses on the ion chromatographic methods for the analyses of natural waters with high ionic strength. At the beginning a natural diversity in ionic composition of waters is highlighted and terminology clarified. In continuation a brief overview of other review articles of potential interest is given. A review of ion chromatographic methods is organized in four sections. The first section comprises articles focused on the determination of ionic composition of water samples as completely as possible. The sections-Selected Anions, Selected Cations and Metals-follow. The most essential experimental conditions used in different methods are summarized in tables for a rapid comparison. Techniques encountered in the reviewed articles comprise: direct determinations of ions in untreated samples with ion-or ion-exclusion chromatography, or electrostatic ion chromatography; matrix elimination with column-switching; pre-concentration with a chelation ion chromatography and purge-and-trap pre-concentration. Different detection methods were used: non-suppressed conductometric or suppressed conductometric, direct spectrometric or spectrometric after a post-column derivetization, and inductively coupled plasma in combination with optical emission or mass spectrometry.Keywords: ion chromatography; sea water; brine; mineral water; anions; cations; metals Natural Diversity of WatersWe restrict the scope of this review and choose to focus on natural waters with high ionic strength in which concentrations of ions extend over several orders of magnitude and therefore these waters present a special challenge for ion chromatographic (IC) analysis, especially if major and minor ions OPEN ACCESS

“…7 In addition, quaternary ammonium, sulfonic and zwitterionic group-functionalized polymers or silica beads were also used for analysis of ionic compounds. [8][9][10][11][12] Recently a variety of HILIC stationary phases have been developed for different purposes, such as separation of polar compounds and peptides by multi-dimensional separation techniques, [13][14][15][16][17][18][19][20] enrichment of lower abundance biological compounds by HILIC solid-phase extraction (SPE), including glycopeptides, proteins and glycoproteins, [21][22][23] as well as analysis of complicated polar samples by using HILIC-MS hyphenated technique, due to good compatibility between organic mobile phase used in HILIC with MS. 24 A common characteristic between IC and HILIC stationary phases is that both contain polar or hydrophilic groups. In IC, ion exchange occurs between charged or chargeable moieties of the stationary phase and the ionic analytes, while HILIC displayed both electrostatic interaction and partition interaction between stationary phase and analytes.…”

A silica based amino stationary phase was prepared by immobilization of propargylamine on azide-silica via click chemistry. This readily prepared click amino stationary phase demonstrated good selectivity in separation of common inorganic anions under ion chromatography (IC) mode, and the triazole ring in combination with free amino group was observed to play a major role for separation of the anions examined. On the other hand, the stationary phase also showed good hydrophilic interaction liquid chromatography (HILIC) properties in the separation of polar compounds including nucleosides, organic acids and bases. The retention mechanism was found to match well the typical HILIC retention.

“…[6][7][8] The emphasis of ion chromatographic application of inorganic anions/cations determination is mostly on the following areas: environmental analysis, power plant chemistry, semiconductor industry, metal processing, pharmaceutics, biotechnology, mining, agriculture, food and beverages, electroplating, and the pulp and paper industry. [31][32][33][34][35][45][46][47][48][49][50][51] In spite of the strong competition from atomic spectrometric techniques, the IC of metal cations is now well established as a relatively cheap method with ease of automation and on-line capability; it is particularly attractive in a wide variety of routine trace analysis. 23,24,26,27,32,33 Compared with the traditional spectroscopic methods, IC offers the advantage of providing information on metal speciation, which can distinguish different metal oxidation states such as Cr(III)/Cr(VI), Fe(II)/ Fe(III), or As(III)/As(V).…”
