of mass spectra will be highlighted. Hardware methods (reflectron, local electrode), which allow improving the quality of the mass spectrum will be briefly discussed. The measurement of composition based on the time-of-flight mass spectrometry will be presented in the last part of this chapter....
Mass spectra of monometallic and bimetallic ruthenium(II) complexes were recorded using a 252Cf time-of-flight mass spectrometer. They proved to be useful for obtaining structural information relating to these complexes. Moreover,they confirmed the nature of the environment around the metal cente...

Time-of-Flight Mass Spectrometry Technical Overview John Fjeldsted Agilent Technologies Introduction Time-of-flight mass spectrometry (TOF MS) was developed in the late 1940's, but until the 1990's its popularity was limited. Recent improvements in TOF technology, including orthogonal accelera- tion...
