The use of organic calibration standards in the enthalpy calibration of differential scanning calorimeters

Abstract The LCG Limited organic DSC calibration standards have been used to carry out the enthalpy calibration of a power compensated DSC in a temperature range (42–147 °C) for which suitable metal standards are not available. The mean calibration factor was in agreement with the value obtained using indium, thus demonstrating that there was no significant error in using indium as a single point calibrant for measurements on the fusion of organic materials at lower temperatures.
