詳細

アプリケーション

Trifluoroacetic acid (TFA) can be used as a solvent in a reverse-phase HPLC system to separate peptides because it enhances peak resolution. It also has low absorption detection wavelengths and is relatively volatile and easily removed. For the majority of peptide separations, TFA has been used at concentrations ranging from 0.05 to 0.1%(6.5-13 mM).
