The solutions were prepared using operating conditions usually employed in the sol\u2010gel synthesis of SiO\n 2<\/jats:sub>\n \u2010TiO\n 2<\/jats:sub>\n materials. In accord with the well\u2010known procedures for controlling the different chemical reactivities of the alkoxides, the pre\u2010hydrolysis of the slower reacting silicon ethoxide and the chelation by acetylacetone of the faster reacting titanium butoxide were performed before mass spectrometric analysis. While LDI\u2010MS did not provide evidence for the presence of mixed Si\u2010Ti species in samples obtained from these reactions, MALDI\u2010MS of samples diluted with chloroform and using 2,5\u2010dihydroxybenzoic acid (DHB) as matrix led to detection of various oligomers with different contents of Si and Ti atoms. The results suggest that the formation of Si\u2010Ti mixed oligomers seems to be the favoured process, especially for solutions in which one of the two components is diluted.
