Abstract
A fullerene mixture was enriched with endohedral metallofullerenes (EMF) using Lewis acid (TiCl4), which took 22 min, whereas the standard method requires about 8 h. An algorithm for assessing small-area chromatographic peaks has been proposed, which has improved the accuracy of determination. For example, the area of the C84 peak was 4.24% using the developed program, while the use of chromatograph software estimated the area of this peak to be 1.78%.
