a test widely used to characterize waxes, DSC measure the amount of energy consumed under controlled heating and cooling rates. Curves of heat flow versus temperature provide insight into the thermal characteristics of wax, including crystalline transitions such as solid-to-solid, solid-to-liquid, and liquid-to-solid. Common values obtained from the curves include the initial and ending temperatures for heat flow and heat of fusion, measured in joules per gram. Also called Thermographic Analysis (TGA)
Analytical method that independently measures the rate of heat flow to a sample against a reference standard of the same temperature. Data are obtained by monitoring the differential heat flow as a function of temperature. DSC can measure heat capacities, phase transitions, dehydration, and decomposition reactions.
