ZSO2-1000A single unit sulfur dioxide detector Introduction
The traditional Chinese medicine sulfur dioxide residual detector series products are used to determine the residual amount of sulfur dioxide in medicinal materials or decoction pieces after sulfur fumigation treatment in accordance with the provisions of the First Law of General Regulation 2331 of the Fourth Part of the Pharmacopoeia of the People's Republic of China.
The main principle of the detection method provided in the Pharmacopoeia is to process the Chinese medicinal materials by distillation. The sulfite series substances in the sample are converted into sulfur dioxide after acid treatment, and then brought into the absorption bottle containing hydrogen peroxide with the nitrogen stream. Hydrogen peroxide oxidizes it to sulfate ion, which is measured by acid-base titration method to calculate the residual amount of sulfur dioxide in medicinal materials and pieces.
Based on strict compliance with the requirements of the Pharmacopoeia, this product integrates functions such as heating, distillation, nitrogen blowing, timing and titration, and can realize the use of multiple instruments in series, thereby maximizing the accuracy and working efficiency of the detection data. .
The ZSO2-1000A single-unit sulfur dioxide detector is mainly suitable for all kinds of traditional Chinese medicine production enterprises, traditional Chinese medicine research institutes, and food production enterprises related to sulfur fumigation. It is used for routine determination of residual sulfur dioxide. Features
(1) The latest sealed infrared ceramic heating technology is selected, which has the advantages of good heat collection, high heating efficiency, long service life, anti-acid and alkali corrosion, and anti-leakage.
(2) Heating countdown function, the heating time can be adjusted as needed, and the heating is automatically stopped at the end of the experiment.
(3) The heating device controls temperature independently and the heating power is adjustable.
(4) The temperature of the stirring device is controlled independently, and the stirring rate is adjustable.
(5) Reserve water and nitrogen circulation expansion interface, which can realize multiple instruments used in series.
