General description

Acetonitrile is a commonly used mobile phase component in various chromatographic techniques, such as high-performance liquid chromatography (HPLC) and liquid chromatography-mass spectrometry(LC-MS).

Application

Acetonitrile can be used as a:
  • Eluent solvent in the chromatographic separation of the PGQ9I peptide.
  • Extraction solvent in the development of a modified QuEChERS (Quick, Easy, Cheap,Effective, Rugged, and Safe) method for the determination of ametoctradin residue in fruits and vegetables using the UPLC-MS/MS method.
