1 Scope

This standard provides guidelines for characterizing single-walled carbon nanotubes (SWCNTs) in mixtures using optical absorption spectroscopy.

This standard is applicable to the measurement of sample diameter, purity and the mass fraction of metallic SWCNTs in total SWCNTs.

When used for nanotube diameter analysis, the applicable diameter range is 1nm~2nm.
