Pressure dependence of several reversed phase liquid chromatographic solvents, including methanol, acetonitrile and mixtures of methanol: water and acetonitrile: water has been investigated. Typical ions, [MH] + , [2M+H] + and [3M+H] + , were recorded as function of source pressure and as a function of the amount of water in the mixture. Ion formation processes in methanol: water and acetonitrile: water are discussed. The influence of liquid chromatographic mass spectrometric solvent pressure on the mass spectra of samples has been demonstrated on an amino acid sample.
