| Abstract: | Singly negatively charged tungstate ion clusters were produced by phosphotungstic anions using 2,5-dihydroxyacetophenone(DHAP) and 2,4,6-trihydroxyacetophenone(THAP) as matrices under matrix-assisted laser desorption/ionization Fourier transform ion cyclotron resonance mass spectrometry(MALDI-FTICR MS). Their gas-phase stability and cluster ion-molecule reactions were studied. It was found that the ion series (PO3)(WO3)n]-, (OH)(WO3)n]- and (C8H5Ox)(WO3)n]- were the main ion series in the mass spectra. The composition and magic numbers of cluster ions were determined. Additionally, the series of hybrid ion clusters were produced through the reaction of matrices and tungstate in the plume of the gas phase. These results highlight the utility of the MALDI-FTICR method for obtaining novel ion clusters and also show the stability of these clusters. |
