Differential scanning calorimeter (DSC)
The current TA Instruments Q2000 DSC was installed in 2011. It is equipped with the proprietary Tzero™ technology which enables a high accuracy in measuring the heat flow. By modulated DSC it is possible to separate reversible and irreversible contributions to the heat flow. A liquid nitrogen cooling system enables temperatures from -180°C to 725°C.
In our Institute DSC is usually used to investigate polymer transitions, such as glass transition temperatures and melting transitions. If suitable pans are used, it can also be used to investigate, for example, reaction isotherms. The application of DSCs is naturally not limited to polymers. Generally, it can be used to investigate any material which exhibits a transition as a function of temperature. Such materials include chocolate, cosmetics, metals etc.
