GB/T 28724-2012 Determination of melting point of solid organic chemicals by differential scanning calorimetry. Suitable for all kinds of solid organic chemicals. Place the sample and reference in a Differential Scanning Calorimeter, program the temperature rise, and measure the Power difference input to the sample and reference with temperature. Determine the melting point according to the endothermic peak of the differential thermal Linear dispersion. The standard specifies the performance indicators of the instrument, such as temperature accuracy, heat flow accuracy, etc., and details the sample preparation, instrument parameter setting and test operation process. According to this standard, the melting point can be accurately determined, providing key data support for solid organic chemical quality control, performance research and related applications.
