Using n-hexane (n-C6H14) and n-dodecane (n-C12H26) as a binary model system, the smearing of isobaric DSC curves, which is a result of a limited heat flow in the calorimeter, is the subject of the present paper. The underlying heat conduction process notwithstanding, the method introduced allows one to simulate the smeared traces of real isobaric DSC curves of binary systems by superimposing a large number of Gaussian curves. The resulting curves have proved to be in good agreement with the experimental data.
