Recent advances in ion chromatography suppressor improve anion separation and detection

New suppressor technology improves the ion chromatographic determination of inorganic anions and disinfection by-products in drinking water

“…The DS-Plus suppressor is the new suppressor that improves and simplifies anion analysis [8]. It is a packed bed suppressor that operates continuously without the need for any external regenerant or reagent.…”

“…Advances in column resins, instrumentation, and even various modes of detection have improved the analysis of ions at trace levels. Advancement in ion chromatography suppressor has also been shown to improve and simplify IC separation and detection [8,9]. This paper discusses the application of this new suppressor for the determination of inorganic anions and IDBPs in reagent water, surface, ground water, and drinking water.…”

Development of a New Suppressor for the Ion Chromatography of Inorganic Cations

“…[1][2][3][4][5][6][7][8][9][10][11][12] Most ion chromatographs with an electrical conductivity detector (ECD) are equipped with a suppressor (such as a column-type suppressor, a micromembrane, 6 or an electrolytically regenerated suppressor used as both a membrane and on ion-exchange resin [6][7][8][9][10][11][12][13] ). The performance of the suppressor determines the detection limit of IC.…”

“…[14][15][16][17] A continuously and electrolytically regenerated packed-bed suppressor (known as Atlas) was made available by Dionex in 2001, which operates with high eluent concentrations, and has a very low dead volume. 10 Other devices, called electrically regenerated ion suppression (ERIS) 7,8 cells and the DS-Plus suppressor, 11 have been introduced by Alltech. These devices generate hydroxide and hydrogen ions (OH -and H + ) by the electrolysis of water on the electrodes, and the generated OH -acts as regeneration ions for neutralizing H + in an acidic eluent and converting the eluent to a low-conductivity solution.…”

Development of an Anti-Analyte Ion Remover Used for Ion Chromatography: Part 1. Examination of a Device for Anion Analysis

“…[1][2][3][4][5][6][7][8][9][10][11][12][13][14] Most ion chromatographs are equipped with a suppressor and an electric conductivity detector (ECD); suppressors, such as a micromembrane [6][7][8] and an electrolytically regenerated packed-bed suppressor, [9][10][11][12][13][14] are important in that it determines the detection limit in IC. [1][2][3][4][5][6][7][8][9][10][11] A suppressor made available by Dionex in 2001 works with high eluent concentrations, and has a very low dead volume.…”
