This standard specifies the measurement method MWCNTs purity, instruments, procedures and results of the analysis representation.
This standard provides for the use of charcoal, thermal gravimetric analysis (TGA), transmission electron microscopy (TEM) and image analysis technology combines measurement
Multi-walled carbon nanotubes (MWCNTs) sample purity method. The purity of the sample content of MWCNTs (mass fraction) represented.
This standard does not apply to poor uniformity or containing chunks of carbon impurity phase samples.
