Abstract
Ion chromatography (IC) represents an important technique for separation of charged and polar compounds. Traditionally, IC is often used for the analysis of small inorganic ions. Due to the development of eluent suppression technology that allows continuous online desalting and conversion of high-salt eluents into pure water, IC has been coupled with mass spectrometry (MS) for the analysis of more diverse range of anionic and cationic analytes. Recent studies have demonstrated that IC-MS is a powerful technique with exquisite detection sensitivity, high reproducibility, and quantitative capability for metabolomic analysis. In this chapter, we provide a brief overview of IC principles and IC-MS for metabolomic analysis.

Abstract
The negative-ion mode of electrospray ionization mass spectrometry (ESI-MS) is intrinsically less sensitive than the positive-ion mode. The detection and quantitation of anions can be performed in positive-ion mode by forming specific ion-pairs during the electrospray process. The paired-ion electrospray ionization (PIESI) method uses specially synthesized multifunctional cations to form positively charged adducts with the anions to be analyzed. The adducts are detected in the positive-ion mode and at higher m/z ratios to produce excellent signal-to-noise ratios and limits of detection that often are orders of magnitude better than those obtained with native anions in the negative-ion mode. This review briefly summarizes the different analytical approaches to detect and separate anions. It focuses on the recently introduced PIESI method to present the most effective dicationic, tricationic, and tetracationic reagents for the detection of singly and multiply charged anions and some zwitterions. The mechanism by which specific structural molecular architectures can have profound effects on signal intensities is also addressed.

Abstract
In previous studies, new electrospray ionization mass spectrometry (ESI-MS) approaches were developed for the highly sensitive detection of singly and doubly charged anions in positive mode ESI-MS by using specially synthesized dicationic and tricationic ion-pairing agents, respectively. By detecting the positively charged ion complex in the positive mode, limits of detection (LODs) for the anions can be lowered by several magnitudes. In this work, we used eighteen newly synthesized tetracationic ion-pairing agents, constructed with different geometries, linkages and cation moieties, for the detection of eighteen triply charged anions of different structural motifs. The LODs for these anions were from ten to several thousand times lower in the positive selective ion monitoring (SIM) mode than in the negative mode. These tetracationic agents also were shown to be useful for the detection of -1 and -2 anions. In addition, the LODs for -3 anions can be further lowered by monitoring the product fragments of the ion-pairing complexes in the single reaction monitoring (SRM) mode.

Abstract
Based on ion chromatography (IC) technology, we have developed a new method that combines ion chromatography with a conductivity detector to separate and determine the substances of glyoxal, glycolic acid, oxalic acid and glyoxylic acid. The ion chromatography was applied for the first time in quantitative determination of substances involved in electrosynthesis of glyoxylic acid. The method has been applied to separate and analyze simultaneously either glyoxylic acid and glyoxal in electroxidation of glyoxal, or glyoxylic acid and oxalic acid in electroreduction of oxalic acid. An aqueous Na2CO3-NaHCO3 or NaOH-Na2CO3 solution was confirmed to be the most desirable eluent. The experimental results demonstrated that the detection sensitivity is ahead of ppm grade, and the variation coefficients such as the retention time, the peak height and the peak area outperform 2%. All the recoveries of the detected substances are ranged between 97 and 103%. The method exhibits advantages of high selectivity, high sensitivity, speediness and simple apparatus requirement. Furthermore, simultaneous determination of a mixture of several substances can be achieved by the developed method, and even a neutral molecule of glyoxal can be also determined by choosing an appropriate composition and concentration of eluent.

Abstract
A suppressed ion chromatography (IC) technique has been evaluated as a chemical monitoring tool for detecting major anions (F-, Cl-, NO3- and SO4(2-)) of condensed steam in geothermal power plants. It is shown that the suppressed IC technique provides a suitable means for preventing possible damage to generating equipment in the geothermal industry. An electrical conductivity detector (0.1 microS sensitivity) with an anion-exchange column (IonPac AS4A-SC), a micro-membrane suppressor (AMMS II), and an isocratic high-pressure pump system were successfully used for detecting low concentrations of inorganic anions. Method detection limits for the anions of interest were <0.184 mg/L. Details of the IC methodology as well as some experimental results obtained during its application for the chemical monitoring of geothermal steam pipes are also described.

Abstract
Current methods for quantitative determination of chlormequat residues in food crops are characterized by rather low recoveries and the need for derivatization (in case of gas chromatography, GC), or by high capital investment (in case of liquid chromatography-mass spectrometry, LC-MS). We propose a cation-exchange chromatography method for the analysis of chlormequat in pears. The method is based on extraction of the target compound with 40 mM HCl, followed by centrifugation and filtration. The filtrate is directly injected into an ion chromatograph equipped with a commercially available cation-exchange column and a suppressed conductivity detection system. While the limit of detection (LOD) (0.5 mg/kg) may not be small enough to allow dietary analysis, the method meets all validation requirements and is an alternative for the existing GC and LC-MS methods in quality control.

Abstract
This paper reports the use of ion chromatography-electrospray mass spectrometry for the separation and structure elucidation of anionic compounds in a complex organophosphate matrix. Conventional HPLC with ion pairing reagents, pH adjustments or use of buffer solutions have limited compatibility with mass spectrometry, as the ion pairing reagents or buffers have to be volatile to be introduced into the mass spectrometer. The choice of volatile additives is limited, resulting in poor chromatography. This paper demonstrates the use of ion-exchange chromatography (IC) for the separation of ionic compounds, followed by mass spectrometry (MS) for the structure elucidation of unknowns. The anionic impurities are separated using an anion-exchange column with aqueous sodium hydroxide as the eluent. Electrospray in the negative ion mode is used to obtain the mass spectra. The elemental composition of an unknown component in the sample is determined by high-resolution mass spectrometry. The coupling of IC to MS provides a new analytical tool to chemists faced with the challenge of separating and analyzing ionic compounds in complex matrices.

Abstract
An all-solid-state ion-selective membrane electrode incorporating a lipophilic anion exchanger was used in a flow-through potentiometric detector for the LC determination of organic anions of biological interest. Different metabolic intermediates (mono-, di-. and tricarboxylic acids, sugar phosphates, and nucleotides) were detected sensitively after separation on a pellicular anion-exchange chromatographic column. The electrode was coated by directly casting the electroactive mixture on a glassy carbon support of 3 mm diameter and used in a wall-jet-type flow cell. The analysis conditions were optimized to obtain both efficient separation and sensitive detection. Calibration curves showed a logarithmic dependence on the injected concentration for concentrations higher than 5.0 x 10(-5) M and a linear dependence for injected concentrations below this value. Under isocratic conditions, detection limits of 5.0 x 10(-7) M (25 pmol) were attained when a sodium hydroxide solution was used as an eluent. No suppressor system was needed in this case. The relative standard deviation for consecutive injections was 0.3% (n = 15), and the electrode lifetime was at least 2 months. The utility of potentiometric detection is further demonstrated in a gradient elution separation for single-run analysis of a synthetic mixture of biochemical compounds containing carboxylic acids, phosphate esters, and nucleotides.

Abstract
We have developed a differential signal detection system for the analysis of liquid chromatographic signals using two or more detectors and a differential amplifier circuit. The proposed detection system is an improvement on conventional chromatography in which signals are detected by means of a single detector. The differential signal detection system eliminates difficulties of isolating minor components of the signal which are masked by the major component, as well as difficulties of separating two components of the signal having similar retention times.

Abstract
An overview is presented of classic and more recent applications of liquid chromatography for the analysis of metal species. The different approaches involving ion-exchange, ion-pair, and chelation separation mechanisms are discussed as well as the new philosophy of simply removing interferents before specific detections of metal ions (alkali and alakaline earths, rare earths, heavy and transition metals). New more selective materials enabling difficult separations and studies on multimodal or hyphenated techniques for metal speciation (e.g. arsenic and chromium) are considered.
