Popis:	We describe an automated HPLC separation of the endohedral metallofullerenes such as SCC{sub 2n} and YC{sub 2n} from empty-cage fullerenes utilizing two polystyrene chromatographic columns (500 and 1000 A) in series. Rapid separation of the metallofullerene fraction from the empty-cage fullerenes (e.g., C{sub 60}) under anaerobic conditions is achieved. For the isolated SCC{sub 2n} fraction, all even-carbon-membered species from Sc{sub 2}C{sub 74} to Sc{sub 2}C{sub 104} were identified by negative-ion chemical ionization mass spectrometry. In addition, Sc{sub 3}C{sub 82} was a prominent component of this fraction. For the separated YC{sub 2n} sample, the mass spectral data indicate the presence of YC{sub 82} and all even-carbon-numbered diyttrium species from Y{sub 2}C{sub 82} to Y{sub 2}C{sub 104}. 14 refs., 7 figs.
