Acetonitrile with 0.1% Formic Acid (v/v), Optima LC/MS, Solvent blends, Fisher Chemical

Description

Formulated for liquid chromatography-mass spectrometry (LC/MS) applications, this solvent is an acetonitrile blend containing 0.1% formic acid (v/v). It belongs to the Optima LC/MS grade line, which is manufactured to meet stringent purity standards suitable for sensitive mass spectrometric detection. The product is packaged in a 1-liter amber glass container to minimize exposure to light. The CAS registry number for the acetonitrile base is 75-05-8. As a pre-mixed solvent blend, it is intended for use as a mobile phase component, where the formic acid serves as a volatile acid modifier to enhance analyte ionization and chromatographic performance in LC/MS workflows, potentially improving reproducibility and reducing background interference.
