CovaChem's LCMS Grade Formic Acid with TFA from CovaChem is of Ultra High Purity ideally suited for sensitive LCMS and HPLC applications. This mixture offers the ability to quickly and easily make one liter of 0.1% Formic Acid with 0.01% TFA enabling the exceptional resolving powers of Trifluoroacetic acid (TFA) without reducing ionization efficiencies.

LCMS Grade Formic Acid is ideally suited as a chromatography additive for use in LCMS applications, where the ion pairing effects of TFA is needed, but high Mass Spectrometry sensitivity is also required.

CovaChem's LCMS Grade Formic Acid with TFA comes in two convenient package sizes (10 x 1.1 mL Ampules and 25 mL bottles). The 1.1 mL Ampules of LCMS Grade Formic Acid are useful for quickly preparing 1 Liter bottles of 0.1% Formic Acid with 0.01% TFA solutions in either water or other organic solvents.
