ABSTRACT:
In a mass spectroscopy method, a primary beam of energetic particles is irradiated onto a target surface containing a sample in which the sample is a collection of analyte molecules contained in a matrix forming compound. When it is required to eject positive analyte ions the matrix forming compound can be a proton donor. When it is required to eject a negative analyte ion, the matrix forming compound can be a proton acceptor.
