Analysis of Tricarboxylic Acids (SI-35 4D)

Please use this column with suppressor type ion chromatography system.

Citric acids and aconitic acids which are tricarboxylic acids were analyzed using IC SI-35 4D (a column for anion analysis). In this analysis, citric acid and isocitric acid, cis-aconitic acid and trans-aconitic acid could be separated.

Sample : 20 μL
1. Citric acid 10 mg/L
2. Isocitric acid 50 mg/L
3. trans-Aconitic acid 20 mg/L
4. cis-Aconitic acid 20 mg/L
