Abstract
In a method for producing selected mass spectra by directing electromagnetic radiation through an optical system onto sample material for vaporization, destruction, excitation and/ or ionization in the microrange, setting the expanse of the irradiation region of the sample by selection of the energy density of the radiation, and detecting the released particles, the radiation power density is varied for producing mass spectra having respectively different proportions of atom and molecule spectra.
