差示扫描量热法(DSC)测定有机化合物纯度,在国外已被作为标准方法,与其他纯度测定法相比,该法突出的优点是简便、快速。所测的为杂质总量,不须分离试样,不用基准物质标定,只要知道主组份的分子量及试样重量,即可测其纯度。 The purity of organic compounds measured by differential scanning calorimetry (DSC) has been used as a standard method in foreign countries. Compared with other purity determination methods, this method has the outstanding advantages of being simple and rapid. Measured as the total amount of impurities, without separation of the sample, without reference material calibration, as long as the main component of the molecular weight and sample weight, you can measure the purity.
