Recent progress and applications of ion-exclusion/ion-exchange chromatography for simultaneous determination of inorganic anions and cations.
One of the ultimate goals of ion chromatography is to determine both anions and cations found in samples with a single chromatographic run. In the present article, recent progress in ion-exclusion/ion-exchange chromatography for the simultaneous determinations of inorganic anions and cations are reviewed. Firstly, the principle and the control for the simultaneous separation and detection of ...
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 کاملAnalysis of inorganic nitrogen and related anions in high salinity water using ion chromatography with tandem UV and conductivity detectors.
Over 97% of the Earth's water is high salinity water in the form of gulfs, oceans, and salt lakes. There is an increasing concern for the quality of water in bays, gulfs, oceans, and other natural waters. These waters are affected by many different sources of contamination. The sources are, but not limited to, groundwater run-off of nitrogen containing fertilizer, pesticides, cleaning agents, s...
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...
