Determination of Purity of DMT by the DSC Method and the Uncertainty Evaluation

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.
