Acetonitrile with 0.1% Formic Acid and 0.01% Trifluoroacetic Acid (v/v), Fisher Chemical

Description

This product is a specialized acetonitrile-based mobile phase containing a blend of two common acidic modifiers. The formulation includes 0.1% formic acid and 0.01% trifluoroacetic acid, with concentrations given on a weight/weight basis. The dual-acid system can be useful for optimizing separations where a single acid does not provide sufficient selectivity or peak shape. The solution is supplied in a 4-liter amber glass bottle to prevent photochemical reactions. Acetonitrile (CAS 75-05-8) is the solvent medium. Such custom blends are utilized in advanced chromatographic method development, particularly for complex samples like protein digests. The packaging follows the EcoSafPak format.
