  • Fully faithful to the legal testing methods of the 2015 and 2020 editions of the Chinese Pharmacopoeia
    Chinese medicine sulfur dioxide analyzer with automatic acid addition, automatic titration, and automatic data calculation
    Usage description
    It can be used for the pre-treatment of the detection of sulfur dioxide residues in Chinese medicinal materials and decoction pieces in the methods specified in the Chinese Pharmacopoeia.
    The 2015 edition of the Chinese Pharmacopoeia stipulates three detection methods for sulfur dioxide: acid-base titration, gas chromatography, ion chromatography, etc. Gas phase and ion chromatography have the advantages of high sensitivity and specificity, but the equipment is expensive, which is not conducive to the popularization and use of primary drug testing systems; acid-base titration has the advantages of simple equipment and low cost, and is a legal testing method prescribed by the Pharmacopoeia. However, since the pharmacopoeia only describes the glass instrument device of this method, the purchase, assembly and implementation of the entire device need to be continuously improved. For example: (1) In addition to the glass instrument device, it needs to be equipped with magnetic stirring, electric heating mantle, titration platform, nitrogen device with flow meter, etc., and assembled. Many units feel that the purchase of equipment is too cumbersome and the assembly is difficult to implement, and cannot carry out this detection method; (2) The assembled devices are diverse, and there are unstable nitrogen flow rates, uneven heating, easy air leakage, and easy bumping during use. , It is susceptible to problems such as the influence of the cooling water source, and the corresponding phenomenon that directly affects the test results such as poor parallelism and low recovery rate; (3) The work efficiency is low. Simultaneous inspection of secondary medicinal materials is time-consuming and laborious.

    Instrument innovation:

    Multifunctional integrated design such as automatic acid addition, far-infrared ceramic heating, automatic timing distillation, built-in compressor cooling, nitrogen blowing control, magnetic stirring, automatic titration, and automatic calculation of results;
    Cooling method: the main engine has a built-in compressor cooling cycle system, a perfect integrated design, no external chiller or tap water cooling;

    Heating method: The host adopts far-infrared ceramic heating device instead of ordinary electric heating furnace or electric heating mantle, which is more energy-saving and has good waterproof effect and acid and alkali corrosion resistance;

    Number of samples: 1-4 digits. Heating power can be single hole monotonous;

    Acid adding method: airtight and automatic acid adding, through the LCD touch screen, the acid can be automatically added by tapping the screen;

    Nitrogen control: the host has a built-in four-way rotor flowmeter, and the flow control range: 60-600ml/min;

    Automatic titration: The main unit has a built-in titration unit, which can be titrated automatically after distillation.

    Applicable units and testing items:
    All levels of Chinese medicine inspection and testing, Chinese medicine research and development and production enterprises, Chinese medicine and other units that need to test the sulfur dioxide residues of Chinese medicine, medicinal materials, and decoction pieces.
