Formic Acid (0.1%) in Water


Convenient, optimized solvent blend for mass spectrometry applications.

Pierce 0.1% Formic Acid in Water

Thermo Scientific Pierce 0.1% Formic Acid (v/v) in Water is an LC/MS-grade preparation with high purity and low UV-absorptivity that is ideal for HPLC and mass spectrometry applications.

This 0.1% Formic Acid in Water is specially purified by a proprietary method and tested to ensure lot-to-lot consistency with a low UV absorbance, providing the most sensitive detection across wavelengths and prolonging equipment life. The chromatography- and spectrometry-grade 0.1% FA in water is 0.2-micron filtered, packaged in solvent-rinsed amber glass bottles and sealed under a nitrogen with PTFE-lined fluorocarbon caps for ultimate protection.

Highlights:

  • Validated – tested more than 20 ways to ensure maximal LC/MS sensitivity
  • Purified – processed, filtered and sealed to extend LC/MS column life
  • Convenient – packaged to eliminate variability and reduce handling

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.
