Separation of Fullerence Molecules in an Eletric-Magnetic Isotope Separator

An electric-magnetic isotope separator was used to separate fullerence molecules C₆₀ and C₇₀ produced by dc contact arc vaporization then extracting method. The potential for the analysis of huge fullerence molecules and the producing of macroscopic quantity of any fullerence molecules was revealed. It also showed that the secondly ionized molecules might be produced in the sample preparing process.
