Cosmosil® Buckyprep
HPLC Column for Fullerene Separation
Nacalai Tesque COSMOSIL Buckyprep Pyrenylpropyl Semi-preparative HPLC Column, 5µm, 120Å, 10mm I.D. x 250mm Length, 1/Pk
Product Number: 37981-91
Separation of fullerenes, especially preparative scale separation, on conventional HPLC columns are always problematic due to the low solubility and low recovery rate of fullerenes. COSMOSIL offers a variety of columns designed for preparative scale separation of fullerenes including higher fullerenes, metallofullerenes and fullerene derivatives.
Features:
| Buckyprep | Standard column for fullerenes separation |
| Buckyprep-M | Designed to separate metallofullerenes |
| Buckyprep-D | For separation of fullerene derivatives |
| PBB | Designed for preparative separation of C60, C70. |
| PYE | Separation of fullerene and structural isomers Separation with high molecular shape selectivity or π-π interactions Excellent separation for structural isomers |
| NPE | Separation of fullerene derivatives Separation with dipole-dipole and π-π interactions Excellent separation for structural isomers |
| CNT | Size-based separation of soluble carbon nanotubes |
COSMOSIL Buckyprep is a Pyrenylpropyl group bonded silica based column specifically designed for fullerene separation. COSMOSIL Buckyprep retains fullerenes very strongly with a mobile phase of 100% toluene and exceeds the injection volume of a standard C18 column by a factor of 35. Therefore, preparative scale separation can be obtained with a 4.6 mm I.D. x 250 mm analytical column.
- Standard column for fullerene separation
- Excellent separation for higher and derivatized fullerenes
