摘要：

Organic acids, namely furan-2,5-dicarboxylic acid and quinolinic acid, occurring in human urine were analyzed by combination of capillary isotachophoresis (cITP) and capillary zone electrophoresis (CZE) with UV photometric detection. Optimal cITP separation conditions were achieved with a leading electrolyte at pH 3.6 and malate as a terminating anion. CZE separations were carried out at pH 5.7 using malate as the carrier ion. The described method allows direct, rapid and sensitive determinations of the furan-2,5-dicarboxylic and quinolinic acids in human urine without additional sample pretreatment step.
