Abstract
There is provided a capillary separated vaporization chamber and nozzle method and device for improved electron ionization liquid chromatography mass spectrometry of samples in a supersonic molecular beam. The device includes a vaporization chamber located upstream of a supersonic nozzle; a capillary separating the vaporization chamber and the supersonic nozzle, means for spray formation from sample in a flowing liquid; a vacuum system into which the supersonic nozzle induces supersonic expansion of the vaporized sample compounds and solvent vapor, for forming a supersonic molecular beam with vibrationally cold sample molecules and vaporized solvent; flythrough electron ionization ion source; mass analyzer; an ion detector and means for data processing of the resulting mass spectral information, for identifying and/or quantifying the chemical content of the sample.
