“…The chelation contribution is strongly depending on sample pH. As with many polymer-coated silica columns, manufacturing is not very reproducible, so eluant composition has to be optimized depending on the various column lots [26,27]. This stability problem was solved by the development of a polymer-based cation exchanger, which is traded as IonPac CS12 [28].…”

Due to the better understanding of the processes taking place at the surface of the stationary phases, the number of ion-exchange materials for ion chromatography (IC) has increased tremendously over recent years. As a result, the multitude of commercially available columns today with their different selectivities for anion and cation chromatography is almost confusing. Hence, the aim of this article is to describe the different principles determining selectivity and ion-exchange capacity and to classify the various ion-exchange materials accordingly. To ensure a fair comparison of these columns, the selectivity differences are illustrated by showing separations of standards rather than individual samples. Keywords Ion chromatography · Stationary phases · Support materials · Inorganic anions and cations · Organic anions and cations Anion exchangersPolymer-based anion exchangers Styrene/divinylbenzene copolymers, polymethacrylate, and polyvinyl resins are the most important organic polymers that are used as substrate materials in the manufacturing process for polymer-based anion exchangers.

“…The Ca 2+ and Mg 2+ content of the feed was determined using an IC technique that included a separation on a Metrosep Cation 1-2 column (Metrohm, Herisau, Switserland) with an eluent containing tartaric acid and PDCA in combination with a conductivity detector (23). The feed contained 0.888% Ca 2+ and 0.223% Mg 2+ , which led, for all applied sample preparation methods, to concentrations of 88.8 mg L -1 Ca 2+ and 22.3 mg L -1 Mg 2+ in the resulting matrix solutions.…”

The contents of transition metal ions iron, copper, zinc, and manganese were simultaneously determined in pig feed using an ion chromatographic technique (IC) preceded by dry ashing. Employing ion exchange, the ions were separated on an IonPac CS5A column used in combination with a pyridine-2,6-dicarboxylic acid based eluent. The separation was followed by spectrophotometric detection after postcolumn reaction with 4-(2-pyridylazo)resorcinol. Dry ashing parameters were varied to assess their role in potential analyte loss. Quantitative recoveries (>95%) were obtained for all analytes with a dry ashing method that included a moderate temperature-time regime and ash leaching support in the form of sonication and heat treatment. The use of HCl as leaching acid and the presence of alkaline earths in the matrix solution did not interfere with the chromatographic separation.

“…Poly(butadiene-maleic acid) (PBMA) is a prepolymer solution containing rich carboxylate groups, which can be used as cation exchanger. [7][8][9] By coating PBMA onto silica gel, Kolla et al firstly developed a weak cation exchanger for the separation of mono-and divalent cations. 7 When a PBMA solution flows through the silica capillary, and is then flushed out by nitrogen, a thin layer of polymer produced is thermally initiated to form a polymerization coating with carboxylate groups.…”

Simple Preparation of Solid-phase Microextraction Fiber with Cation Exchange Capacities Using Poly(butadiene-maleic acid)

A simply way was proposed to prepare solid-phase microextraction (SPME) fiber with cation-exchange functional groups by the thermally initiated radical polymerization of poly(butadiene-maleic acid) (PBMA) copolymer onto a silica capillary. The capacity of the fiber coating could be easily controlled by fabricating successive layers of PBMA. The performance of the fiber combined with ion chromatography was evaluated by choosing Mg(2+) and Ca(2+) as model analytes; ∼13 and ∼51-fold enrichment factors for Mg(2+) and Ca(2+) were obtained, respectively.
