Abstract
The invention relates to the automatic cleaning of ion sources inside mass spectrometers, especially the cleaning of ion sources where the ions are generated by matrix-assisted laser desorption (MALDI). The invention consists in cleaning the electrodes of the ion source, which are contaminated with organic material, in the mass spectrometer itself by etching with reactive ions produced by an electrically generated gas discharge in a specially admitted reactant gas.
