WebAmines with short alkyl (triethylamine, trimethylamine, diisopropylethylamine) chain are not hydrophobic enough to retain well in reverse phase chromatography. Slight hydrophobicity and strong basic properties of tertiary amines provide enough interaction with mixed-mode stationary phases to guarantee good retention on a Primesep 200 column.
