The most commonly used solvents or solvent blends include LC-MS grade water and acetonitrile, with ion pairing agents such as trifluoroacetic acid (TFA), formic acid (FA) or heptafluorobuteric acid (HFBA). These solvents are available as single component formulations or convenient blends. Solvents are manufactured in an ISO9001 facility and are provided with a Certificate of Analysis. Solvents and blends have been validated using Thermo Scientific™ Mass Spectrometers.

  • High purity—processed, filtered and sealed to help extend LC-MS column life
  • More choices—solvents and solvent blends to meet a variety of applications/needs
  • Stable—store for more than one year at room temperature
  • Validated—products evaluated with over 20 specifications measured and fully tested using Thermo Scientific Mass™ Spectrometers
