A non-suppressed ion chromatographic method by connecting anion-exchange and cation-exchange columns directly was developed for the separation and determination of five inorganic anions (sulfate, nitrate, chloride, nitrite, and chlorate) and three cations (sodium, ammonium, and potassium) simultaneously in explosive residues. The mobile phase was composed of 3.5 mM phthalic acid with 2% acetonitrile and water at flow rate of 0.2 mL/min. Under the optimal conditions, the eight inorganic ions were completely separated and detected simultaneously within 16 min. The limits of detection (S/N = 3) of the anions and cations were in the range of 50-100 g/L and 150-320 g/L, respectively, the linear correlation coefficients were 0.9941-0.9996, and the R.S.D. of retention time and peak area were 0.10-0.29% and 5.65-8.12%, respectively. The method was applied successfully to the analysis of the explosive samples with satisfactory results.

“…Gas chromatography (Lee et al 2012;Lee et al 2013;Ligor et al 2008;Ryhl-Svendsen and Glastrup 2002;Sokoro et al 2007), capillary electrophoresis (Klampfl et al 2000;Kubáñ and Boček 2013;Kubáň et al 2014;Pantučkova et al 2013;Suárez-Luque et al 2006;Travassos Lemos et al 2015), and ion chromatography (Brudin et al 2010;Käkölä et al 2008;Kuo 1998;Lodi and Rossin 1995;Magne et al 1998;Rantakokko et al 2004;Walford 2002;Wojtczak et al 2013) are techniques most often used for the determination of low-molecular-mass carboxylic acids in various materials, including food products. Complications arising from the major sample components, e.g., proteins, lipids, and salts, in the examination of the samples of biological matrices, can generate the necessity of coupling of the technique with a suitable sample preparation step for their elimination.…”

“…Little sample preparation steps and small samples required for analysis are the advantages of IC analytical procedures. The possibility of the use of ion chromatography for rapid identification and quantification of small organic acids, among them formic acid, in various food and beverages samples was documented (Lodi and Rossin 1995;Magne et al 1998;Walford 2002;Brudin et al 2010;Wojtczak et al 2013). The content of organic acids in foods can serve as a marker of degradation and fermentation processes occurring during production and storage steps.…”

Monitoring of human exposure to formic acid is important due to its high biological activity. Elevated amounts of formic acid in the human body can cause serious damage to optical nerve, respiratory failure, renal failure, deep metabolic acidosis, coma, and eventual death from cardiovascular arrest. Such symptoms are characteristic for methanol poisoning owing to rapid enzymatic conversion of methanol into formic acid of substantially higher than methanol alone toxicity. Early diagnosis of methanol consumed and formic acid produced is essential for successful medical treatment. Small amounts of methanol can be introduced into the human body with alcoholic drinks (methanol can be a by-product of distillation and fermentation processes). A fast method for the determination of formates in commercial alcoholic drinks by the use of suppressed ion chromatography (IC) with conductometric detection has been developed. The applicability of two anion-exchange columns, Metrohm Metrosep A Supp 7 and Dionex IonPac AS9-HC, for selective detection of formates in mixtures with acetates and common inorganic ions occurring in such kind of samples was examined. Quantitative isolation of formates from the matrix can be reached in less than 10 min using 3.6 mmol/L Na 2 CO 3 as an eluent. Preliminary minimizing of alcoholic matrix by the evaporation (under IR source) allows to improve the quality of chromatographic results. The evaluated amounts of formates in two different Polish commercial products, BAbsolwent vodka^and BGolden Rum,^tested in the work were in the range of 0.2-3.1 mg/L. The 96-107% recoveries of the formates from the examined samples were found out.

“…IC provides good repeatability and a wide range of applications used for water quality control procedures [4–6], atmosphere monitoring [7], food analysis [8, 9] and within the pharmaceutical industry [10]. Since the introduction of IC much research has been conducted in order to address ion-exchange selectivity and improvement of separation of anions, particularly in the development of stationary phases.…”

Synthesis and properties are described of multilayered stationary phases containing quaternary amine functional groups used for the analysis of inorganic anions by ion chromatography. The bonded phases were characterized by elemental analysis, solid state 13C NMR spectroscopy and chromatographic methods. The surface of polyhydroxyethyl methacrylate (solid support) was coated with polymeric layers formed by condensation polymerization of primary amine with diepoxide. Each layer of the anion exchange stationary phase consisted of methylamine and 1,4-butanedioldiglycidyl ether copolymer. A series of stationary phases with different number of polymerized layers were tested. Separation of inorganic anions, such as F−, Cl−, NO2−, Br−, NO3−, were performed. Aqueous hydroxide, carbonate and bicarbonate solutions were used as mobile phases.
