DSC is a thermal analytical method where the difference in the heat needed to raise the temperature of a reference and sample is measured as temperature function. The sample and reference are kept at nearly the same temperature throughout the process. The temperature during this phenomenon is made in such a way that the sample temperature rises linearly as a time function. The reference must have a heat capacity over various temperatures that need to be scanned. This article highlights more information on Differential Scanning Calorimetry.
We use this technique to examine polymeric materials so that we can identify their thermal transitions. The thermal changes we look out for are the melting temperature, glass transition temperatures as well as crystallization temperatures. These temperatures are essential when it comes comparing different materials. You, however, have to use other complementary techniques to identify unique compositions.
We use the DSC technique to study liquid crystals. It is a known factor that there are components that go from solid to liquid state and goes through a third state, where they display properties of their previous form during this transition. To observe and learn small energy changes that happen during the transformation of a component from solid to liquid and finally to liquid crystalline, you have to use the DSC technique.
If you wish to study oxidative stability of components, then this method is the best option to go for. To have a successful outcome, we conduct them at an airtight chamber. We will hold the tests isothermally by altering the atmosphere of the component you are testing. For instance, the element is brought to the desired temperature in a nitrogen atmosphere, and then oxygen is released into the system. If oxidation occurs, there would be a deviation on the baseline.
We offer safety screening services. The component you wish to be tested is put in a non-reactive crucible that withstands pressure. When there exothermic happening, it will be used to determine the stability of the component to heat. If you need to use this thermal analytical method to test out components, reach out to Kinetica, INC today for precision and accuracy testing.
