The caloric calibration of scanning calorimeters

Theory and Practice of Modulated Temperature Differential Scanning Calorimetry

“…In most cases this can be neglected. Where it is important to account for this, it can be done by measuring the non-reversing signal of the relevant glass transition when other processes are not present (see [38]). …”

“…The apparent heat capacity of the sample can then be calculated by dividing the empty-pan corrected heat flow by the average heating rate. The heat capacity of sapphire as a function of temperature has been established to high accuracy [38]. Thus, these known values can be compared with the apparent values calculated in the foregoing experiment.…”

A high-sensitivity differential scanning calorimeter with magnetic field for magnetostructural transitions

“…Data can be fitted by the curve: K (mV/W)ϭ1.4 ϫ10 Ϫ8 T 4 -2.0ϫ10 Ϫ5 T 3 ϩ5.1ϫ10 Ϫ3 T 2 ϩ0.86 T, which is also plotted in the figure. It is interesting to note that the room temperature value is around 10 times larger than the sensitivity for a conventional DSC, 13 and that at temperatures as low as 10 K, a reasonably high value is still obtained.…”

Reversible melting of polyethylene extended‐chain crystals detected by temperature‐modulated calorimetry

“…The heat-flow rate was calibrated with the heat of fusion of In (28.62 J g Ϫ1 ). 56 The melting temperature of In was also measured in the quasiisothermal mode with a 0.05 K temperature amplitude after calibration in the standard DSC mode to identify any differences between two modes of measurement. In the standard DSC mode, the (onset) melting temperature of indium, a secondary temperature standard, was set to its value of 429.75 K at 10 K min Ϫ1 .…”
