Formic acid 99,5 LC-MS, Pierce™
Formic acid

Thermo Scientific Pierce Formic Acid is high-purity solvent supplied in bottles as a convenient, contamination-free alternative for preparing elution solvents for HPLC separations of protein and peptides.


Formic acid is a common component of reverse-phase mobile phases that provide protons for LC/MS analysis. The presence of a low concentration of formic acid in the mobile phase is also known to improve the peak shapes of the resulting separation. Unlike trifluoroacetic acid (TFA), formic acid is not an ion-pairing agent and it does not suppress MS ionization of polypeptides when used as a mobile-phase component.
