Product principle:

The Tianjin Jingtuo Instrument for Traditional Chinese Medicine Sulfur Dioxide Residue Determination mainly consists of a heating module, a distillation module, a cooling circulating water module, and a nitrogen blowing module. The heating module is equipped with high, medium, and low heating rate control functions, which can achieve precise control panel of heating efficiency; The distillation module is made of high borosilicate material, which has good heat resistance and is sturdy and durable; The cooling water circulation system can choose an external cooling water circulation machine (built-in optional) to ensure cooling effect. The nitrogen blowing module can be connected to an external nitrogen generator or nitrogen cylinder, and is equipped with a high-precision gas flow meter to strictly control the nitrogen blowing rate

Product Introduction:

The main principle of the detection method provided in the pharmacopoeia is to process Chinese medicinal materials by distillation. After acid treatment, the sulfite series substances in the sample are converted into sulfur dioxide, which is then carried into an absorption bottle containing hydrogen peroxide with nitrogen gas flow. The hydrogen peroxide oxidizes it into sulfate ions, which are determined by acid-base titration to calculate the residual amount of sulfur dioxide in the medicinal materials and decoction pieces. On the basis of strictly following the requirements of the pharmacopoeia, this product integrates functions such as heating, distillation, water circulation, and nitrogen blowing, and can provide processing for 3-5 samples (blank samples, parallel samples) simultaneously, greatly improving the accuracy of detection data and reducing working time.
