Determination of C60 and C70 fullerenes in geologic materials by high-performance liquid chromatography

Abstract It is demonstrated that high-performance liquid chromatography (HPLC) is an excellent and reliable analytical method for the determination of the C 60 and C 70 fullerenes extracted from geologic samples because the analysis is carried out at room temperature, is non-destructive (fullerenes can be recovered), and is easily calibrated with synthetic fullerenes. The determination of fullerenes in geologic materials is greatly empowered by the preseparation of fullerenes from organics on a “big” HPLC column.
