Coupling a magnetic bottle multi-electron spectrometer with a liquid micro-jet device: a comprehensive study of solvated sodium benzoate at the O 1 <i>s</i> threshold

We have developed a magnetic bottle time-of-flight electron-electron coincidence spectrometer to perform measurements on solvated molecules in liquid micro-jet. present here the first results obtained after ionization of oxygen 1 s inner-shell sodium benzoate and show possibilities filter out electron signal arising from phase water gas phase. Both photoelectrons Auger electrons spectra (unfiltered filtered) are presented.
