Advances in the determination of inorganic anions by ion chromatography.
The time period covered for this review includes articles published from 1997 to 1999, with the addition of a few classic references. The purpose of the review is to include the most relevant works from each topic area of the determination of inorganic anions by ion chromatography, including new sample pretreatments, new separation methods, new detection systems and the latest applications in t...
متن کاملDetermination of Inorganic Cations and Anions in Chitooligosaccharides by Ion Chromatography with Conductivity Detection
Chitooligosaccharides (COSs) are a promising drug candidate and food ingredient because they are innately biocompatible, non-toxic, and non-allergenic to living tissues. Therefore, the impurities in COSs must be clearly elucidated and precisely determined. As for COSs, most analytical methods focus on the determination of the average degrees of polymerization (DPs) and deacetylation (DD), as we...
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 کاملDetermination of inorganic anions by capillary ion-exchange chromatography using polyethylenimine-coated octadecyl-bonded phases.
The utility of a cationic polymer polyethylenimines (PEI) for coating some commercially available silica-based stationary phases packed in capillaries of 0.32 mm i.d. and 10 cm long was studied for the separation and direct UV detection of inorganic anions (iodate, bromate, nitrite, bromide, and nitrate ions). With a super-endcapped octadecylated silica stationary phase, which yielded the best...
متن کاملInterpretation 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...
