Characterization of several carbonaceous soots from pyrolysis and combustion processes by field ionization mass spectrometry shows the absence of peaks at 720 and 840 Da corresponding to C{sub 60} and C{sub 70} fullerenes. This absence coupled with the fact that these peaks are clearly seen in the soot obtained by vaporizing graphite in {approximately}150 Torr of He leads to the conclusion that the commonly encountered pyrolysis and combustion soots do not contain significant (larger than 0.1%) amounts of fullerenes.
