Title: Elemental Analysis of a Single-Walled Carbon Nanotube Candidate Reference Material
Published: October 15, 2010
Abstract: A material containing single-walled carbon nanotubes (SWCNTs) together with other carbon species, cata-lyst residues, and trace element contaminants has been prepared by the National Institute of Standards and Technology for characterization and distribution as Standard Reference Material SRM 2483 Carbon Nanotube Soot. Neutron activation analysis (NAA) and inductively coupled mass spectrometry (ICP-MS) procedures were selected to characterize the chemical composition. A SWCNT material provided by the National Research Council Canada was included in the studies. Catalyst residues at percent mass fraction level were determined with independent NAA procedures and a number of trace elements, including selected rare earth elements, were determined with NAA and ICP-MS procedures. The results in the investigated materials agreed well among the NAA and ICP-MS procedures and good agreement of measured values with certified values was found in selected SRMs included in the analyses. Based on this work mass fraction values for catalyst and trace elements will be assigned in the candidate SRM.
