Ion Chromatography

2013
The basic principles and fundamentals of modern ion chromatography are presented with focus on a key separation mechanism, including ion exchange, ion exclusion, chelation, and zwitterionic interactions. The most common types of ion chromatographic columns, eluents, and detection modes are briefly discussed, together with possible applications of ion ...

Anion Analysis of Ionic Liquids and Ionic Liquid Purity Assessment by Ion Chromatography

, 2017
The simultaneous determination of halide impurities (fluoride, chloride, bromide, and iodide) and ionic liquid (IL) anions (tetrafluoroborate, hexafluorophosphate, and triflimide) using ion chromatography was developed with a basic, non-gradient ion ...

Ion Pairing Chromatography

Critical Reviews in Analytical Chemistry, 2008
The present state of ion-pair chromatography (IPC) is reviewed. Emphasis is placed on the theoretical modeling of the retention behavior of charged, zwitterionic, and neutral solutes, since the theory provides the generally good understanding of the factors affecting the separation.

Ion Chromatography

, 2017
Ion Chromatography (IC) was introduced in 1975 by Small, Stevens and Baumann as a new analytical method. Within a short period of time, ion chromatography developed from a new detection scheme for a few selected inorganic anions and cations to a ...

Determination of epichlorohydrin by ion chromatography

Journal of Chromatography A, 2000
In this work we developed a new method for epichlorohydrin determination with suppressed ion chromatography. The technique is based on a reaction between the analyte and sulfur(IV) to form a product with a terminal sulfonate group that can be analyzed by anion-exchange chromatography. The reaction conditions were optimized as a function of temperature,

Multiple reaction monitoring-ion pair finder: a systematic approach to transform nontargeted mode to pseudotargeted mode for metabolomics study based on liquid chromatography-mass spectrometry.

Analytical Chemistry, 2015
Pseudotargeted metabolic profiling is a novel strategy combining the advantages of both targeted and untargeted methods. The strategy obtains metabolites and their product ions from quadrupole time-of-flight (Q-TOF) MS by information-dependent ...

[3] Ion-exchange chromatography

1996
Publisher Summary Over the years, electrophoretic techniques were the leading bioanalytical tools for biopolymers. Slab gel electrophoresis has yielded spectacular results, in resolving closely related nucleic acids of high molecular mass. Isoelectric focusing and sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) have served well ...

Ion-exchange chromatography

Analytica Chimica Acta, 1967
Abstract A review is given of variables which affect the separation factors in ion-exchange chromatography. In favorable cases the influence of complex formation, pH, and eluant concentration can be predicted by simple calculations, whereas the interaction forces inside the resin phase are still largely unexplored.
