We have applied MALDI/TOF MS to the analysis of metal oxides by using chelating agents as matrices. The identification of metals is performed without any complicated pretreatment. Moreover, the oxidation numbers of the metals are determinable by using suitable chelating reagents. This simple method is successfully applied to the analysis of metal elements in natural crystal stone (Pyrite, FeS2).
Key words: MALDI/TOF MS, Copper, Iron, Pyrite
