Residual sulfur dioxide analyzer

Product Introduction

The main principle is to process Chinese medicinal materials by distillation according to the detection methods provided in the pharmacopoeia. 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, and the acid-base titration method is used to determine the residual 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 into one, and can provide processing of 3-6 samples (blank samples, parallel samples) simultaneously, greatly improving the accuracy of detection data and reducing working time.

Compliant with standards:

The series of products of traditional Chinese medicine sulfur dioxide residue determination instrument are used to determine the residual sulfur dioxide in medicinal materials or decoction pieces that have been fumigated with sulfur according to the provisions of General Rule 2331 * * in Part 4 of the Pharmacopoeia of the People's Republic of China

Product Usage:

This instrument is mainly suitable for various traditional Chinese medicine production enterprises, Chinese medicine research institutes, as well as food production enterprises related to sulfur fumigation, etc., and is used for routine determination of sulfur dioxide residue.

Product principle:

The traditional Chinese medicine sulfur dioxide residue analyzer mainly consists of a heating module, a distillation module, and a nitrogen blowing module. The heating module is equipped with high, medium, and low heating rate control functions, which can achieve a control panel for heating efficiency; The distillation module is made of high borosilicate material, which has good heat resistance and is sturdy and durable;. The nitrogen blowing module can be externally connected to a nitrogen generator or nitrogen steel cylinder, and is equipped with a high-precision gas flow meter to strictly control the nitrogen blowing rate

Main features of the product:

Select a sealed infrared ceramic heating sleeve, which has good heat collection performance, high heating efficiency, and can prevent equipment damage caused by liquid leakage.

Full touch screen control, human-computer interaction interface, simple and easy to control operation.

The heating device has independent temperature control and adjustable heating power.
