Size exclusion chromatography (SEC) is an effective tool for the purification of multiwall and singlewall carbon nanotubes (MWNTs and SWNTs). The method is applied to surfactant stabilised dispersions of raw material produced in a Kraetschmer generator. Besides the removal of carbon nanospheres, metal particles and amorphous carbon, a length separation of the NTs is achieved. Raman spectra of the liquid dispersions illustrate the successful purification. AFM investigations of NTs determined the length separation.
