  • Title: [Simultaneous determination of 11 organic acids in fruit juice by ion exclusion chromatography].
    Author: Guo DH, Xia L.
    Journal: Se Pu; 2001 May; 19(3):276-8. PubMed ID: 12541818.
    Abstract:
    A method for the quantitative determination of 11 organic acids (oxalic acid, citric acid, tartaric acid, malic acid, ascorbic acid, lactic acid, succinic acid, formic acid, acetic acid, glutaric acid and fumaric acid) in fruit juice was developed successfully. It was based on an ion exclusion chromatographic separation under the conditions of isocratic elution with 17 mmol/L sulphuric acid solution with the ICE-ION-300 ion exclusion column, and the UV detection at 210 nm. The precision of the method was investigated and the relative standard deviations were from 1.5% to 9.8% (n = 10).
