"WebMar 11, 2005 · TEA is probably used more for its ability to suppress tailing of basic compounds than for its ion-pairing ability (although it does both). TBA is a more generally used choice for ion-pairing of anions. As you point out, since it's a quat, the ionization is pH-independent. -- Tom Jupille LC Resources / Separation Science Associates " - Teaa buffer
