Determination of some organic acids and inorganic anions in beet sugar by ionic HPLC

This work deals with the identification and quantitative evaluation of sulfates, nitrates, chloride, acetic, lactic and formic acids. Determination was carried out using a Dionex ion chromatograph with a conductivity detector. Different white and raw sugar samples have been analysed with the aim of evaluating their quality. Organic acids production seems related to storage conditions rather than processing. Inorganic anions may be used to determine the crystallization quality.
