In the range of environmental applications of ion chromatography, inorganic anions are, by far, the most important. The primary reason for this is the lack of alternative methods for anion analysis, which is not the case for cation analysis where many other instrumental techniques are readily available [e.g., atomic absorption spectrometry (AAS) inductively coupled plasma-atomic emission spectrometry (ICP-AES) and ICP-mass spectrometry (ICP-MS)]. [Pg.802]

Ohta and Tanaka reported a method for the simultaneous analysis of several inorganic anions and the cations Mg + and Ca + in water by ion-exchange chromatography. The mobile phase includes 1,2,4-benzenetricarboxylate, which absorbs strongly at 270 nm. Indirect detection of the analytes is possible because their presence in the detector leads to a decrease in absorbance. Unfortunately, Ca + and Mg +, which are present at high concentrations in many environmental waters, form stable complexes with 1,2,4-benzenetricarboxylate that interfere with the analysis. [Pg.618]

Conductance monitors can be used where the sample components are ionic and providing that the conductivity of the mobile phase is very low. They are used extensively in ion chromatography (p. 147) for the detection of inorganic anions, some inorganic cations and ionized organic acids. [Pg.133]

In order to prevent interference with such inorganic anions as fluoride, chloride, and nitrate which occurs with Na2C03/NaHC03 eluents, a weak aqueous eluent, i.e., Na2Bi+0y, was used to achieve adequate separation. The detection limit in such an ion chromatographic analysis is limited by the conductance of the suppressed eluents, but the development of ion chromatography exclusion (ICE),... [Pg.599]

An overview and discussion is given of literature methods published after 1989 devoted to the ion-interaction chromatographic determination of inorganic anions. Seventy references are quoted. Ion-interaction chromatography makes use of commercial reversed-phase stationary phase and conventional high-performance liquid chromatography instrumentation. The basis of the technique, the modification of the stationary phase surface, the choice of the ion-interaction reagent as well as the dependence of retention on the different variables involved are discussed. Examples of application in the fields of environmental, clinical and food chemistry are presented. The experimental conditions of stationary phase, of mobile phase composition as well as detection mode, detection limit and application are also summarized in tables. 1997 Elsevier Science B.V. [Pg.1198]
