Trialkylamines (YK-421)

Trialkylamines were separated using cation chromatography column,
IC YK-421. By using the mobile phase stated below, hydrophobic interaction dominates ioninc-interaction. Therefore, shorter chain alkyl amines (less hydrophobic) will elute before longer ones.

Sample : Alkylamines 100mg/L, 20?L

1. Trimethylamine, TMA

3. Tripropylamine, TPA

4. Tributylamine, TBA

5. Trihexylamine, THA
