In mass spectroscopy, in general, variable magnetic field or time-of-flight methods are used in mass spectroscopy. But the both give us only the mass-to-charge ratio (m/z) of ion, which means both of a single-charged ion of lighter atom and a multiple-charged ion of heavy atom and molecule at the same time. The further identification of ion required a much large facility such as accelerator. In order to investigate the including multiple-charged ion by easier method, we have tried to detection of multiple-charged ion of Xe by using charge-changing cell and simple electrostatic energy analyzer as well as TOF-MS.
