The pure Carbon Fullerenes that come out of our reactor after chemical extraction of the raw material will contain:
Carbon 60 (C60)
Carbon 70 (C70)
Carbon 76 (C76)
Carbon 78 (C78)
Carbon 84 (C84), etc.
These are the pure Fullerene molecule spheres, and each will have its own properties and different concentration in the Raw Fullerene Soot. After further processing and refinement, the individual fraction of C60 and C70 is isolated into a powder of different purity levels.
So, when we express the purity of the Carbon 60 99.5 percent, it will contain a minimum of 99.5% C60 and less than 0.499% C70, C76, C78, C84 and higher.
Then C60 99.99% will contain less than 0.001% of C70, C76/C78, C84.
Example: 100 grams of C60- 99.5% will contain a minimum of 99.5 grams of C60 and less than 0.4999 grams of C70, C78, C76, C84 and higher.
The testing of the purity is performed using a High Pressure/Performance Liquid Chromatography technique in which the Carbon Fullerene sample is dissolved back into solvent and tested for its purity.
Lastly, the VOD grade goes through additional processing to remove the solvents out of the C60.
The solvent will consist of Toluene, Hexanes, and Benzene.
