FIELD: nanotechnologies.
SUBSTANCE: invention relates to ecology and material science, namely nanotechnology, and can be used for quantitative determination of carbon nanostructures (CN), particularly carbon nanotubes, in solid and liquid samples and various media. For this purpose, in the analyzed sample with unknown weight content of CN, mass of catalysts present in CN of accompanying impurities is measured by mass spectrometry with inductively coupled plasma or inductively coupled plasma atomic emission spectrometry. Content of CN in the analyzed sample is determined by comparing the mass of the process impurity in the analyzed sample with the mass of this impurity in a standard sample containing a known mass of CN.
EFFECT: invention increases reliability of quantitative measurement of CN in samples of different composition without changing physical and chemical properties of samples.
