Transition Temperatures DSC provides rapid and precise determinations of transition temperatures using minimum amounts of a sample. Common temperature measurements include the following:
• Melting  • Crystallization   • Glass Transition  • Polymorphic Transition  • Thermal Stability • Liquid Crystal  • Oxidation Onset  • Protein Denaturation  • Cure Onset  • Solid-Solid Transition 
This composite shows typical shapes for the main transitions observed in DSC.
Heat Flow Heat Flow is the universal detector, as all physical and  chemical processes involve the exchange of heat. As such, the DSC Heat Flow signal is commonly used to measure and quantify a wide variety of transitions and events, often  occurring in the same material as a function of temperature. This example shows a pharmaceutical material which is  undergoing a variety of physical changes as it is heated from subambient through its melting temperature. DSC is sensitive to all of these events.
