Superior Analytical Separation

This column was the first of the Cosmosil columns designed specifically for fullerene separation. Developed in the early 1990’s, this column still stands as the benchmark of HPLC column for fullerene separation. The Buckyprep was designed for mass separation of fullerenes with the use of analytical HPLC equipment. The Buckyprep’s extraordinary retention capabilities allow separation of up to 100 mg of fullerenes per day when using a 250 mm x 4.6 mm I.D. analytical column.

Preparative Separation of Higher Fullerenes

The superior fullerene retention of the Cosmosil Buckyprep Column provides researchers with the ability to produce higher quantities of purified fullerenes using analytical HPLC equipment. As an example, a 25 cm x 4.6 mm analytical Buckyprep Column can be injected with as much as 25 ml (approx. 6.35 mg) of fullerenes. Using only 500 ml of 100% strength toluene for the mobile phase and an elution time of 30 minutes, a researcher can separate 100 mg of higher fullerenes from this column in less than 8 hours.

Compatibility with Stronger Solvents

The Cosmosil Buckyprep Column also allow researcher to use stronger and therefore smaller amount of solvents in the separation process. Typically, 100% strength toluene is recommended as the mobile phase, but if time is a critical factor in fullerene separation, chlorobenzene may be used to reduce the separation time down to one-third of toluene-induced separations.

Mass Preparation of Higher Fullerenes

A Cosmosil Buckyprep Column offers significant improvement in loadability. A 250 x 20 mm I.D. preparative column can be loaded with up to 110 mg (45 ml @ 2.5 mg/ml) of fullerene mixture and produces very sharp separation of fullerenes with in 50 minutes.

Separation of Endohedral Metofullerenes

The purification and isolation of Endohedral Metallofullerenes can be easily be performed using a two-stage HPLC Method. ( Sc2@C₈₄, Sc3@C₈₂, Y@C₈₂, Pr@C₈₂ and Gd@C₈₂)
