Application of a deconvolution method to construct aqueous phase diagram
چکیده انگلیسی

Signals obtained from a differential scanning calorimeter (DSC) include instrumental effects of time lag due to slow thermal conductance. The dynamic response of samples is influenced by the effects, especially on the occasion of phase transitions. A deconvolution method calibrating the instrumental effects for the heat-flux DSC is reviewed and applied to the eutectic mixtures of aqueous solutions of NaCl and glycerol to determine the phase behaviors without ambiguity in the interpretation of the peak profile. The method is useful for the measurements with fast heating runs, which inevitably have larger time lag but is required for e.g. polymeric systems to reduce reorganization on heating. The results of the deconvolution are well agreed with the data in the literature.
