Teaching is concentrated in the faculties and schools, and the departments deal with research, which is also conducted by institutes and chairs, at the same time responsible for knowledge promotion.
It Differential calorimetry of Tracking (DSC) it is the technique of Thermal Analysis used more frequently. This technique measures the changes of enthalpy of the samples due to changes in its physical properties and chemists depending on the temperature or the time. Is used to analyse and to study polymers as thermoplastic, thermostable or elastomers as well as metallic material stickers, alimentary, pharmaceutical, chemical products, and composites
In order to request the analysis of samples for DSC, you have to get yourselves with the staff responsible for the team in touch.
It be necessary to inform of the toxicity and precautions of storage of the samples. If they do not come to search, the surpluses of sample will be destroyed in the deadline of a week from the delivery of results.
This technique measures the heat absorbed or given off by a sample when this undergoes a programme of temperatures. The DSC is a differential technique, the flow of heat is calculated from the difference of temperature of the sample with respect to a reference. The encapsulated sample and he references it (generally an empty capsule) they position about the sensor, placed in an oven with very precise control of the temperature.
Is created one programme of temperatures depending on the process to monitor (fusion, crystallisation, vitreous transition, curate...). In the case of a dynamic programme, it be necessary to specify the initial temperature, the final temperature and the speed to the one who is wanted to be made the warming or cooling (ºC/ minute). In the case of an isothermal programme, it be necessary to specify the temperature of the isotherm and its duration.
In the graph resulting from the analysis the flow of heat (mW) absorbed is represented or afterwards for the sample depending on the temperature or the time.
Examples of thermal processes that can be determined by Differential Calorimetry of Tracking:
