ZSO2-4000A quadruple sulfur dioxide detector Introduction
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, water circulation and nitrogen blowing. It can provide 3-5 samples (blank samples, parallel samples) at the same time, thus greatly improving the detection Data accuracy and reduced working time.
The instrument is mainly applicable to various traditional Chinese medicine production enterprises, traditional Chinese medicine research institutes, and food production enterprises related to sulfur fumigation. It is used for the determination of conventional sulfur dioxide residue. Features
(1) The sealed infrared ceramic heating sleeve is selected, which has good heat collection and high heating efficiency, and can prevent equipment damage caused by liquid spillage.
(2) Full touch screen control, human-computer interaction interface, easy operation and control.
(3) The heating device controls temperature independently and the heating power is adjustable.
(4) Heating countdown function, buzzer reminder, automatically stop heating.
(5) Built-in cooling circulating water system improves the condensation efficiency and saves energy. And it can be shut down with one key, and replenish water with one key.
(6) Configure independent precision nitrogen flow control system. It can also be equipped with a nitrogen generator. Technical parameters
