Ion chromatography eliminates the need to use hazardous reagents and it effectively distinguishes among the halides (Br−, Cl−, and F−) and the oxyhalides (ClO2−, ClO3−, and BrO3−), and the oxy-ions (PO43−, SO42−, NO2−, and NO3−).

Since its introduction in 1975, ion chromatography (IC) has become a routine analytical method for the determination of inorganic ions, especially anions present in various matrices.

The determination of anions and cations needs more time to balance the two different columns. Although conventional colorimetric, electrometric, or titrimetric methods are available for determining individual anions, ion chromatography provides a single instrumental technique that may be used for their rapid, sequential measurement.

The obtained LOD values are in the range of 2.13–32.61 ng L−1. Determination of Inorganic Anions in astewaterW by Ion Chromatography INTRODUCTION The determination of common inorganic anions in environmental waters, such as wastewater and drinking, ground, and surface waters, is one of the most important applications of ion chromatography (IC) worldwide. The National Primary Drinking Water Standards in the United States specify a Maximum Contaminant Level (MCL) for a number of inorganic anions, including fluoride, nitrite, and nitrate. Sometime, the amount of … In addition, the need to measure the concentration of the disinfection by-products chlorite, chlorate, and bromate has arisen. GBH Enterprises, Ltd.

Determination of Anions by Ion Chromatography 1 SCOPE AND FIELD OF APPLICATION This method is suitable for the determination of inorganic anions in Ammonia Solution in the range 100 ppb to 50 ppm m/v. Determination of Anions by Ion Chromatography 1. © 2019 Elsevier B.V. All rights reserved. The separation effect mainly depends upon the column, mobile phase, and flow rate. John D. Pfaff Inorganic Chemistry Branch Chemistry Research Division. ENVIRONMENTAL MONITORING SYSTEMS LABORATORY OFFICE OF RESEARCH AND DEVELOPMENT U.S. ENVIRONMENTAL PROTECTION AGENCY CINCINNATI, OHIO 45268 DETERMINATION OF INORGANIC ANIONS BY ION CHROMATOGRAPHY. Application Note 133 Introduction The determination of common inorganic anions in drinking water is one of the most important applications of ion chromatography (IC) worldwide. Water quality in the U.S. is legislated through the Safe Drinking Water Act (SDWA) and the Clean Water Act (CWA). Ion chromatography is one of the most popular methods in the determination of anions in various sample matrixes. “4110 DETERMINATION OF ANIONS BY ION CHROMATOGRAPHY”, Part 2000 - Physical and Aggregate Properties, Part 4000 - Inorganic Nonmetallic Constituents, Part 5000 - Aggregate Organic Constituents, 4110 DETERMINATION OF ANIONS BY ION CHROMATOGRAPHY. The determination of common inorganic anions in environmental waters, such as wastewater and drinking, ground, and surface waters, is one of the most important applications of ion chromatography (IC) worldwide. New IEC-CIC system is proposed for analysis of trace inorganic anions in weak acids. An ion chromatography (IC) method has been proposed for the determination of seven common inorganic anions (F(-), H(2)PO(4)(-), NO(2)(-), Cl(-), Br(-), NO(3)(-), and SO(4)(2-)) and/or five common inorganic cations (Na(+), NH(4)(+), K(+), Mg(2+), and Ca(2+)) using a single pump, a single eluent and a single detector. An improved “heart-cut” column-switching method combining ion-exclusion column, monolithic anion exchange concentrator and capillary anion-exchange column is developed and successfully applied for the determination of inorganic anions (Cl−, Br−, NO3− and HPO42−) at trace level in weak acids. Determination of Anions by Ion Chromatography 1 SCOPE AND FIELD OF APPLICATION This method is suitable for the determination of inorganic anions in Ammonia Solution in the range 100 ppb to 50 ppm m/v.

The obtained limits of detection (LODs) are in the range of 2.1–32.6 ng/L based on the s/n = 3 and injection volume of 50 μL. More than 15 various weak acids and hydrogen peroxide are analysed. 2001 Jun 22;920(1-2):127-33. Optimization of chromatography for the selectivity of eluent was conducted at a flow rate of 1.0 mL/min. Determination of the common anions such as bromide, chloride, fluoride, nitrate, nitrite, phosphate, and sulfate often is desirable to characterize a water and to assess the need for specific treatment. With the development of new separation methods, novel stationary phases, a great variety of detectors, etc. For the Examination of Water and Wastewater. Therefore, method procedures are written based on the assumption that they will be performed by analysts who are formally trained in at least the basic principles of chemical analysis and in the use of the subject technology.
