Water with 0.1% Trifluoroacetic Acid, Optima LC/MS, Solvent Blends, Fisher Chemicals

Description

This is a pre-mixed LC/MS solvent consisting of water with 0.1% trifluoroacetic acid (TFA), classified under Fisher Chemical's Optima LC/MS grade. It is used in liquid chromatography-mass spectrometry as a mobile phase component, where TFA functions as an ion-pairing reagent and acidity modifier, often for peptide and protein separations. The solvent is provided in a 2.5-liter amber glass container, which shields it from light exposure. The product listing references the CAS number for water (7732-18-5). It is sold as one unit (1 EA) and is formulated to meet the purity requirements critical for reliable and reproducible mass spectrometric analysis.
