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 Anions in Acid Rain by Ion Chromatography
INTRODUCTION The increase in acidity of wet and dry atmospheric depositions has been attributed to the increase of SO 2 and NO 2 emissions from stationary and mobile pollution sources. The acid rain problem has reached dramatic proportions throughout many regions of the United States, Europe, Canada, and Japan. Monitoring air and rain is essential, not only for assessing the effects of pollutan...
متن کاملDetermination of anions of milk by ion chromatography
The anions of milk have been successfully analysed by ion chromatography coupled with suppressed conductivity detection. With an appropriate sample preparation (ultrafiltration alone, or combined with dry mineralization), this method enabled simultaneous identification and quantification of chloride, phosphate and citrate ions with good repeatability (relative standard deviations of about 1%). ...
متن کاملAnalysis of anions in beer using ion chromatography
The majority of anions found in beer are a consequence of impurities derived from the water used during the brewing process. The process of beer manufacture consists of malting, brewing and fermentation followed by maturation before filtration and finally storage. Strict quality control is required because the presence of certain anions outside strictly defined tolerance limits can affect the f...
متن کاملPartition/Ion-Exclusion Chromatographic Ion Stacking for the Analysis of Trace Anions in Water and Salt Samples by Ion Chromatography.
A new analytical methodology for a simple and efficient on-line preconcentration of trace inorganic anions in water and salt samples prior to ion chromatographic determination is proposed. The preconcentration method is based on partition/ion-exclusion chromatographic ion stacking (PIEC ion stacking) with a hydrophilic polymer gel column containing a small amount of fixed anionic charges. The d...
