The mass spectra of Co(II) acetylacetonate and Co(III) acetylacetonate were measured by MALDI-TOF-MS. Complex peaks, such as the adduct peaks and cluster peaks, were observed in their mass spectra. The two compounds had different mass spectra. The compounds could be identified by their mass spectra. TLC-MALDI-TOFMS was applied to a mixture of these compounds. The separated spots on the TLC plate gave similar mass spectra to that of the conventional MALDI-TOFMS, when a mixture of solvents with acetylacetone was used as the developing and eluting solvents.

Key words: TLC-MALDI-TOFMS, Co(II) acetylacetonate, Co(III) acetylacetonate
