Carbon nanotubes are promising candidates for numerous applications because of very unique nanostructures and possess remarkable mechanical and electronic properties. For this reason there is an urgent need for standards for carbon nanotube (CNT) manufacturers, as well as for scientific and health-related investigations done with CNTs. In response to this need, we are in the process of developing a single-walled carbon nanotube reference material (SWNT). We were involved in the characterization of a candidate SWNT reference material for elemental content using instrumental neutron activation analysis (INAA) and cold neutron prompt gamma activation analysis (CNPGAA). A total of 22 elements were found to have measurable amounts; 21 additional elements were determined to be less than the detection limits of the techniques. Based on the elemental content, it was decided that this material was not suitable for production of a standard reference material (SRM) or reference material (RM). A second SWNT material, CoMoCAT SWeNT SG 65 freeze dried powder has been selected as a candidate material. Results will be discussed in the presentation.
