Determination of Organic Acids in Wastewater Using Ion-Exclusion Chromatography and On-Line Carbonate Removal
17 Nov 2011This study by Dionex shows a method for determining organic acids in wastewater using ion-exclusion chromatography and on-line carbonate removal. Inorganic anions are eluted in the void volume and the Dionex CRD 200 removes carbonate on line. The results show that this combination allows the accurate determination of organic acids in a wastewater sample.

Ion ChromatographyIon chromatography, also known as ion exchange chromatography, is a high-performance liquid chromatographic technique used for the separation and identification of ions or polar molecules in a sample, including proteins, nucleotides and amino acids. Equipment includes ion exchange columns, ion exclusion columns, ion chromatography systems, pumps, and detectors. Find the best ion chromatography equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Environmental Monitoring and TestingEnvironmental monitoring and testing uses handheld portable analyzers, kits, spectrometers or chromatography systems for air, water, soil, food and other sample testing. Useful features of analyzers such as BOD and COD include portability, easy calibration, automation and sensitivity. Environmental test kits for pH, water, moisture, etc, should be accurate, sensitive, reliable, fast and easy to use.Water PurificationThere are a number of water purification methods available to remove contamination from laboratory water. These systems include demineralization, reverse osmosis, filtration and ultrafiltration. A combination of methods is sometimes necessary to achieve purified water suitable for use in experiments.Waste Water
