In industries such as pharmaceuticals, biotechnology, and chemical engineering, the presence of insoluble particles may affect the purity, stability, and safety of products. Therefore, detecting and controlling insoluble particles in products is very important.

Working Principle:

The working principle of the insoluble particle detector is mainly based on the principle of light scattering. When the laser beam passes through the liquid sample to be tested, the insoluble particles in it will scatter light, generating a light scattering signal. These signals are captured by precision detectors and converted into electronic data through the internal circuitry of the instrument. By analyzing these data, the size and quantity of particles can be accurately determined.

Detection method:

According to the inspection regulations of the Chinese Pharmacopoeia 2020 edition and USP, there are three methods for detecting insoluble particles: photoresist methodＬ ｉｇｈｔ　 Ｏ ｂｓｃｕｒａｔｉｏｎMicroscopic counting methodＭ ｉｃｒｏｓｃｏｐｉｃAnd dynamic image methodＦ ｌｏｗ　 Ｉ ｍａｇｉｎｇAmong them, the quality release methods specified by photoresist method and microscopic counting method, while dynamic imaging method is currently recommended for research, especially for protein injection. But the new oneＵＳＰ １７８８The chapter also includes the dynamic image method, which represents that the dynamic image method will have more application scenarios in the future.

The insoluble particle detector can detect particles at the micrometer level. According to publicly released information, the insoluble particle detector has high resolution and sensitivity, and can detect particles at the micrometer level. Its detection range typically ranges from 1 micron to several hundred microns, covering most particle sizes that may have an impact on drugs, medical devices, and the environment.

Application scope:

Insoluble particle detection and determination instruments are widely used in various fields, such as environmental monitoring, food industry, pharmaceutical and medical, manufacturing, etc.

In terms of environmental monitoring, it can detect and count the content of fine dust in the air, assisting in the assessment of air quality.

In the food industry, it can be used to detect particles in beverages and food, ensuring product quality and safety. In the field of pharmaceuticals and healthcare, it can be used to detect particles in medicines to ensure their purity. In the manufacturing industry, it can be applied for quality control, detecting particles in liquid products, and preventing equipment problems caused by particles.
