ABSTRACT:
The invention relates to the ionization of analyte molecules on a solid surface close to atmospheric pressure as an ion source for mass spectrometers. The invention uses a spray mist from an electrospray apparatus to ionize the analyte molecules, for example a spray mist created by spraying pure water, which generates predominantly multiply charged ions of the analyte molecules which are particularly suitable for fragmentation.
