Column Specifications



COSMOSIL Buckyprep-M is a phenothiazinyl group bonded silica based column specifically designed for metallofullerene separation. Metallofullerenes are retained more strongly than other fullerenes on this column. COSMOSIL Buckyprep-M is also effective for the separation of higher fullerenes and fullerene derivatives.


Column Size 4.6 mm I.D. x 150 mm
Mobile Phase Toluene
Flow Rate 1.0 ml/min
Temperature 30 °C
Detection UV 312 nm
Sample Sample courtesy of Prof. H. Shinohara, Department of Chemistry, Nagoya University.
