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

Description

This solvent is a prepared mixture of acetonitrile containing 0.01% (volume/volume) trifluoroacetic acid (TFA). It is provided in a 4-liter amber glass bottle with EcoSafPak secondary containment. The addition of TFA, a common ion-pairing agent and mobile phase modifier, makes this product ready-to-use for specific chromatographic applications, particularly in reversed-phase HPLC analysis of peptides and proteins. The acidic modifier helps improve peak shape and resolution for basic analytes. The amber glass shields the contents from light. This pre-mixed format offers convenience and consistency for laboratories performing routine analyses, eliminating the need to prepare and standardize the acidified solvent in-house.
