Application:Stability: In the experiment of reverse phase chromatography for isolation of peptides and proteins, using trifluoroacetic acid (TFA) as the ion-pairing reagents is a common approach. Trifluoroacetic acid in the mobile phase can improve the peak shape and overcome the problem of the peak broadening and trailing issue through interaction with hydrophobic bonded phase and residual polar surface in a variety of models. Trifluoroacetic acid can bind to the positive charge and polar groups on the polypeptide in order to reduce the polar retention, and bring the polypeptide back to the hydrophobic inverting surface. With the same way, trifluoroacetate shield the residual polar surface in fixed phase. The behavior of TFA can be understood as it stuck in the phase surface of the reverse phase fixed phase, while having interaction with the polypeptide and column bed.
Trifluoroacetic acid has an advantage over other ion modifier due to that it is volatile and can be easily removed from the sample preparation. On the other hand, the maximum UV absorption peak of trifluoroacetic acid is less than 200 nm, and thus having very small interference on the detection of polypeptides at low wavelengths.
Varying the concentration of trifluoroacetic acid can slightly adjust the selectivity of polypeptide on reverse phase chromatography. The impact is very useful for optimizing separation conditions, increasing the amount of information contained in complex chromatography assay (such as the fingerprint of polypeptide).
Trifluoroacetic acid was added to the mobile phase in a general concentration of 0.1%. At this concentration, most of the reversed-phase column can produce good peak shape. In contrast, if the concentration of trifluoroacetic acid is significantly below this level, the peak broadening and tailing would become very obvious.
Trifluoroacetic acid has a good efficacy in the separation of proteins and other macromolecules. However, during the actual usage, we have a difficult time in controlling TFA concentrations because it is a volatile substance. If you configure it for a long time, it will be volatile causing change in the concentration. After completion of preparing it, it must be sealed for prevention of its evaporation.
