GB/T 28723-2012 "Determination of Purity for Organic Solid Chemicals Using Differential Scanning Calorimetry" specifies the method for determining the purity of solid organic chemicals using differential scanning calorimetry. This method is based on the van 't Hoff equation, which calculates the main component purity of the sample by precisely measuring the melting process of the sample and utilizing the relationship between the melting point depression and impurity content.
