CovaChem's LCMS Grade Formic acid plus TFA is an optimally formulated ion pair additive for numerous pH sensitive applications where ion pairing effects can be of benefit. This preformulated mixure contains 0.1 mL of TFA per 1 mL of Formic acid, so that when 1.1 mL is added to 1 Liter of solvent, a 0.1% Formic Acid / 0.01% TFA w/w buffering system is created.
