Acetonitrile with 0.05% Trifluoroacetic Acid (TFA), Optima LC/MS, Fisher Chemical

Click to view available options

Ideal high purity organic mobile phase for LC/MS and UHPLC-UV applications, specifically protein and peptide separations

  • Suitable for LC-MS and UHPLC-UV
  • Lower TFA content enhances separations by minimizing ion suppression
  • Pre-blended mobile phase simplifies preparation leaving more time to run and analyze samples
  • TFA is a common mobile phase additive and ion pair reagent in chromatography
  • Complementary to the 0.05% TFA aqueous blend -- LS1154
