Higher Resolution Separation of Organic Acids and Common Inorganic Anions in Wine
2 May 2011The method described in this application note shows a high resolution separation of the organic acids and inorganic acids found in wine. This approach is applied to the separation and detection of organic acids and inorganic anions in four red and white wine samples. Ion chromatography (IC) with suppressed conductibility detection is an excellent way to separate a large variety of organic acids and detect them with high sensitivity along with inorganic anions.

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.
