Interpretation of solute retention of some monovalent inorganic anions in anion-exchange chromatography using a dicarboxylic Acid as an eluent.
In single-column anion-exchange chromatography, the retention volume of some monovalent inorganic anions (Cl(-), Br(-), NO(3)(-), NCS(-) and NO(2)(-)) were observed as a function of the pH of a mobile phase at a fixed concentration of 2-phenylmalonic acid or 1,4-benzenediacetic acid used as an eluent. The experimental retention volume of such an anion was decreased with an increase in the pH of...
متن کاملSeparation of inorganic anions by liquid chromatography with crown ether as eluent additive.
Inorganic anions were separated on a reversed-phase stationary phase dynamically modified with crown ether as a selector in capillary ion chromatography. The eluent contained crown ether, acetonitrile and a salt. Free and cation-trapped crown ether molecules in the eluent were adsorbed on a hydrophobic stationary phase such as triacontyl-functionalized silica (C30). The eluent cations trappe...
متن کاملOnboard determination of submicromolar nitrate in seawater by anion-exchange chromatography with lithium chloride eluent.
Ion-exchange chromatography using a high-capacity anion exchanger with UV detection was applied to the determination of nitrate in seawater. Major ions in seawater samples did not affect the peak shape and the retention time of the nitrate when an alkaline metal cation-chloride solution was used as an eluent at high concentrations (0.5-2 mol/l). At a wavelength of 220 nm, the peak of bromide wa...
متن کاملIon-exclusion/cation-exchange chromatography (IEC/CEC) on a weakly acidic cation-exchange resin using on acidic eluent,
Ion-exclusion/cation-exchange chromatography (IEC/CEC) on a weakly acidic cation-exchange resin using on acidic eluent, developed by Tanaka et al. in 1994, has been employed to monitor the quality of environmental water samples such as acid rainwater and river water, to analyze body fluid samples such as saliva, and to evaluate water purification by photocatalytic materials.1–8 One advantage of...
متن کاملAnalysis of carbonic acid in water samples by ion-exclusion chromatography with pure water as eluent.
A simple, sensitive and rapid ion-exclusion chromatographic method for the simultaneous separation of carbonic acid and short chain organic acids (formic acid, acetic acid, and propionic acid) has been developed. A weakly acidic cation exchange resin column TSKgel OApak-A was used for the separation; pure water, owing to its lower background conductance, was employed as eluent in order to obtai...
