Why does Phenomenex use DEA over TEA as the primary basic modifier in most of their Lux application notes?

PROTOCOL

LUX HPLC UHPLC CHIRAL

Last Updated: 8/9/2014

Both DEA (diethylamine) and TEA (triethylamine) are widely published as good basic modifiers for improving peak shapes on polysaccharide-type chiral columns.  We chose DEA for our initial screening data, and have continued with such routinely to maintain consistency.  TEA is also just as effective, and also commonly used successfully in practice on our Lux polysaccharide chiral columns.
