This standard specifies the method, instrument, analysis procedure, result presentation method for measuring the purity of multi-walled carbon nanotubes. This standard provides a method for measuring the purity of multi-walled carbon nanotubes (MWCNTs) samples, using a combination of charcoal burning, thermogravimetric analysis (TGA), transmission electron microscopy (TEM), image analysis. The purity is represented by the content (mass fraction) of multi-walled carbon nanotubes in the sample. This standard is not applicable to samples, which have poor uniformity OR contain large carbon phase impurities.
