| Abstract: | The results of a study on interfacing an Orbitrap mass analyzer with direct ion injection to a surface assisted laser desorption/ionization (SALDI) ion source are presented. Osmium complexes with 8-mercaptoquinoline were studied. Titanium oxide thin films prepared by electron beam evaporation were found an effective emitter of the ions of the test complexes. It was demonstrated that interfacing the Orbitrap mass analyzer to a SALDI source can significantly improve the analytical performance of this method in comparison to a typical combination of SALDI/time-of-flight mass spectrometer. |
