This Technical Specification provides guidelines for the characterization of compounds containing single-wall carbon nanotubes (SWCNTs), using optical absorption spectroscopy. The purpose of this Technical Specification is to describe a measurement method for establishing the diameter, purity, and ratio of metallic SWCNTs to the total SWCNT content in the sample. The analysis of the diameter is applicable to a diameter range of 1 nm to 2 nm.
