  • High purity and exceptional clarity - allows sensitive, nondestructive peptide detection at low UV wavelengths in reverse-phase HPLC protein and peptide separation systems
  • High-performance packaging - TFA packaged under nitrogen in amber glass ampules or bottles with protective PTFE-lined fluorocarbon caps to ensure TFA integrity
  • Economical convenience - Choose the TFA format that works best for your application. In just a few seconds, 1 ml ampules can be used to prepare 1 liter of fresh 0.1% v/v trifluoroacetic acid solution for the mobile phase in reverse-phase chromatography
  • Applications of Trifluoroacetic Acid (TFA), Sequencing grade:
    • Ion pair reagent for reverse-phase HPLC
    • Protein/peptide sequencing
    • Protein/peptide solubilizing agent
    • Solid-phase peptide synthesis
    • Amino acid analysis
    • Making 0.1% solutions of trifluoroacetic acid (w/v vs. v/v)
  • Trifluoroacetic acid (TFA) is the most commonly used ion pairing agent for use in reverse-phase HPLC peptide separations because it sharpens peaks and improves resolution, is volatile and easily removed, has low absorption within detection wavelengths. It is manufactured to the highest specifications to ensure the integrity of your data, maximize sensitivity in your assay and to prolong the life of your equipment.
