The energy required to heat the sample is compared to an inert reference material at the same temperature. The pan filled with sample will require extra energy to heat through a transition such as a melting point because extra energy is required to change the molecule from a solid to a molten state.
Our deliverable is certainty – high quality data, test reports and certifications that you can rely on when making decisions about your materials and components. Validating the specifications, value and safety of your raw materials, products and assets.
Both pans are heated at the same temperature ramp rate and the energy required to keep each one heating is continuously measured. Certain equipment allows the temperature range to be extended.

If the sample under test requires more 3d418 compared to the reference, it is indicated as an endotherm. The ISO procedures provide additional information not supplied by this test method. To perform DSC testing, a small amount of material is heated at a predetermined rate. Dd3418 with an FTIR analysis, a DSC thermal scan can be used to help further identify certain types of materials by their melting points and is a useful tool for checking plastic parts or resins for contamination not seen by FTIR.
The signal from the DSC is usually plotted with temperature on the X-axis and heat energy on the Y-axis. Element offers a wide range of experience in consulting, analytical testing, and industrial chemistry. Ready to make an inquiry or request a quote? True heats of fusion are to be determined in conjunction with structure investigation, and frequently, specialized crystallization techniques are needed.
Most commonly used for detecting glass transition temperature and other thermal properties, differential scanning calorimetry is one of the most efficient and cost-effective polymer test methods available.
