By using instrumental neutron activation analysis (INAA) it has been shown that commercial C60 products contain considerable amounts of sulfur impurity. This element could be found in all C60 samples of three main producers which, in fact, necessitated to study the capabilities of the INAA sulfur determination in more detail. Although only one sample did contain a surprisingly high sulfur amount of about 8%, even the sublimed C60 sample showed a sulfur content of about 0.02%.
