Purity Analysis of Trade Produced C-60 Fullerene

The article compares the product purity of fullerene C-60, synthesized in different laboratories. The content of main product impurities was determined by liquid chromatography, infrared spectroscopy and mass spectrometry. It is shown that only one method of chromatographic analysis, the results of which are given in the certificates of goods, is not enough for detecting detect impurities.
