    DESCRIPTION

    General description

    Trifluoroacetic acid is commonly used as a mobile phase additive in liquid chromatography-mass spectrometry (LC-MS).
    Features:
    • Extensive QC testing ensures the highest specifications.
    • Optimized to improve ionization and resolution.
    • Extremely low levels of inorganic and organic impurities.
    • Manufactured specifically for accurate and fast LC-MS.

    Application

    Trifluoroacetic acid may be used as a mobile phase additive for the analysis of basic compounds in biological samples using hydrophilic interaction liquid chromatography-electrospray ionization coupled to tandem mass spectrometry (HILIC–ESI/MS/MS) and reversed-phase liquid chromatography coupled to tandem mass spectrometry (RP-LC-MS/MS).
