Patent ID: 7044635

Claim:
A temperature correction method for a thermal analysis apparatus, which measures a temperature of a measurement sample by temperature measurement means and measures at least one of electric resistance, dielectric constant, electric capacity, thermal electromotive force, and thermally stimulated electric current while changing the temperature of the measurement sample, the method comprising the steps of: measuring temperature of a measurement sample by the temperature measurement means; measuring a melting point temperature of a reference substance while changing a temperature of the reference substance; measuring an electric current flowing through the reference substance or a voltage applied to the reference substance while applying a load force to the reference substance; determining the temperature of the reference substance measured at the time when the measured electric current does not flow any more or the applied voltage is not detected any more to be a melting point; and correcting the temperature measured by the temperature measurement means, based on a difference between the measured melting point temperature of the reference substance and a known value of the melting point temperature of the reference substance.
