In the production process of medical hydrogen peroxide, inline process refractometer plays an important role in many links!

Relationship
The main component of medical hydrogen peroxide is an aqueous solution of hydrogen peroxide (H₂O₂), and its concentration is a key indicator for measuring product quality. The inline process refractometer uses the change in the refraction angle of light in hydrogen peroxide media of different concentrations to accurately reflect the concentration of hydrogen peroxide by detecting the refractive index. The two are closely related. The inline process refractometer provides real-time and accurate concentration monitoring data for medical hydrogen peroxide production, helping operators to control the production process and ensure that the product meets quality standards.

1. Raw material procurement and inspection
1.1. Purity detection: The main raw materials for hydrogen peroxide production include hydrogen, oxygen, deionized water, etc. The inline process refractometer can perform real-time purity detection on purchased deionized water and other raw materials. If the deionized water is not pure enough and contains other impurities, the refractive index will change. The refractometer detection can detect problems in time to prevent unqualified raw materials from entering the production process.

1.2. Initial concentration screening: For directly purchased hydrogen peroxide raw materials or other intermediate products containing hydrogen peroxide, the inline process refractometer can quickly detect their approximate concentration, determine whether they meet production requirements, and provide basic data for subsequent production operations.

2. Synthesis reaction process monitoring
2.1. Reaction process tracking: In the synthesis reaction of hydrogen peroxide, the degree of reaction is related to the amount of hydrogen peroxide generated, which in turn affects the refractive index of the solution. The inline process refractometer monitors the refractive index changes in real time, allowing operators to intuitively understand the degree of reaction and determine whether the reaction has reached the expected stage, so as to adjust the reaction conditions in time, such as temperature, pressure, reactant flow, etc.

2.2. Reaction endpoint judgment: When the refractive index reaches a relatively stable value and meets the refractive index range corresponding to the concentration of the target product, it can usually be considered that the reaction is close to the end point. The operator can decide whether to terminate the reaction based on the display data of the refractometer to avoid overreaction or incomplete reaction and ensure the yield and quality of the product.

3. Concentration and purification
3.1. Concentration control: When concentrating crude hydrogen peroxide, the inline process refractometer continuously monitors the refractive index of the solution. As the water evaporates and the concentration of hydrogen peroxide increases, the refractive index will change accordingly. The operator accurately controls the degree of concentration based on the data fed back by the refractometer to ensure that the concentration standard required for medical hydrogen peroxide is reached.

3.2. Purification effect monitoring: The purification process aims to remove impurities and by-products in the product. The presence of these substances will affect the refractive index of hydrogen peroxide. Through real-time detection by the inline process refractometer, it can be determined whether the purification operation is effective. If the refractive index fluctuates greatly or deviates from the normal range, it means that the purification effect is not good, and it is necessary to adjust the purification process parameters or check the operation of the equipment.

4. Quality inspection and packaging
4.1. Finished product concentration detection: Before packaging, the inline process refractometer performs the last concentration test on the finished medical hydrogen peroxide to ensure that the product concentration meets the relevant standards and quality requirements. Only products with a refractive index within the specified range can enter the packaging process, thereby ensuring the quality stability and consistency of the factory products.

4.2. Batch stability assessment: For medical hydrogen peroxide produced in different batches, the inline process refractometer can quickly detect the refractive index of each batch of products, and then evaluate the concentration stability between batches. If it is found that the refractive index between batches is greatly different, the cause can be analyzed in time and corresponding measures can be taken to adjust to ensure the reliability of product quality.
