  • Using qualitative and quantitative analyses, the differential scanning caloric (DSC) method for determining purity of DMT is introduced, with uncertainty evaluated. A measurement comparison with the mass balance (MB) method validated the results of the DSC method. The chemical composition of a DMT sample was determined by gas chromatography with tandem mass spectrometry and a fourier transform infrared spectrometer. The certified value was studied by the DSC method.
