애플리케이션
Trifluoroacetic acid (TFA) can be used as an ion-pairing agent 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 can be 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).

Trifluoroacetic acid (TFA) remains the dominant mobile phase additive for reversed-phase high-performance liquid chromatography (RP-HPLC) of peptides after more than two decades since its introduction to this field. Generally, TFA has been employed in a concentration range of 0.05-0.1% (6.5-13
