Determination of Organic Acids in Fruit Juices and Wines by High-Pressure IC

1 May 2014

The determination of organic acids plays an important role when testing the authenticity of fruit juices and wines. Certain fruit juices, such as those obtained from pomegranate and various types of berries, are popular because of their high levels of antioxidants and the resulting putative health benefits. The high economic value and the large market demand for these juices make them a likely target for adulteration. This application note describes method development to determine organic acids in fruit juices and wines using ion chromatography (IC) with suppressed conductivity detection.

UHPLC and HPLCHigh performance liquid chromatography (HPLC) and ultra high performance liquid chromatography (UHPLC), also known as UPLC, are analytical techniques used to separate, identify and quantitate components of complex mixtures including biological samples such as proteins and lipids as well as chemical mixtures of pesticides, drugs and oils. Both techniques are liquid chromatographic methods but differ by operating pressures (HPLC < 6000 psi < UHPLC ). Components of HPLC and UHPLC systems include columns, detectors, pumps, autosamplers and column heaters. Explore a range of UHPLC and HPLC columns for your specific sample needs including reverse phase, normal phase, ion exchange, HILIC, ion exclusion and size exclusion columns. For more specialized HPLC, explore FPLC, countercurrent LC and simulated moving bed systems.
