In present work the results are presented relative to the use of thermally exfoliated graphite and some other graphite containing supports in investigation of binuclear complexes of cuprum (II) by means of laser desorption ionization mass spectrometry. Mass spectra of complexes obtained using 2,5-dihydrobenzoic acid as a matrix are described and interpreted. The presence of physically adsorbed water and volatile organic compounds in supports under investigation was studied by temperature-programmed desorption mass spectrometry and their effect on ionization processes and on composition of mass spectra was clarified. The assumption is expressed and discussed, based on mass spectrometric data, concerning determinative role of electric fields in ion formation processes of binuclear complexes of cuprum (II) on the surface of nanostructured graphite containing supports.
