The Indium melting peak, measured with DSC 204, shows the typical shape of a melting peak of a pure metal:
- The endothermal peak increases nearly linearly up to the maximum. This behavior is caused by the so-called thermal resistance.
- After the maximum the melting peak decreases nearly exponentially. A more precise analysis indicates that the decay is the sum of more then one exponential functions.
According to all standards, the temperature during DSC measurements is measured on the reference side. Therefore, the given temperature is not the temperature inside the sample.In order to receive the true sample temperature the measurement is to correct regarding to thermal resistance.
