Possibilities of organic acid determination by ITP in red type wines.Peer-reviewed article

J. KAROVIČOVÁ, J. POLONSKÝ, M. DRDÁK

The content of organic acids was analysed in red type wines by isotachophoresis. In the samples there were determined tartaric, lactic, malic, succinic and acetic acids. For the optimal separation of analysed components this electrolytic system, dod proce itself: leading electrolyte: 8 . 10^-3 mol . l^-1 HCl + e - amino-capronic acid + 1 . 10^-3 mol . l^-1 CaCl₂ (pH 5) terminating electrolyte: 1.10^-2 mol . l^-1 capronic acid.

Keywords: tartaric acid, lactic acid, malic acid, succinicacid, acetic acid, isotachophoresis
