Abstract

Two-step liquid chromatographic separation (LC) has been applied to soot extract and the identification of higher fullerenes has been accomplished by LC-MS measurements using an ESI interface. The first separation step is preparative-scale LC using a 50 mm i.d. column packed with monomeric octadecylisilica (ODS) because elution is mainly controlled by relative molecular mass. 39 batches of five fractions each were collected and then as the second separation step each fraction was analysed by analytical-scale LC using a conventional column of a polymeric ODS phase which can elute fullerenes according to shape and structure. This stationary phase can also separate many isomers of higher fullerenes, consequently the existence of several higher fullerenes larger than C86 has been confirmed and their UV-Vis spectra were obtained by the photodiode array detection system coupled to the analytical LC.
