The principle and main applications of insoluble particle detector
Date: 2025-10-27Read: 5
The insoluble particle detector mainly achieves particle detection through photoresist method, microscopic counting method, and dynamic imaging method. The photoresist method uses particles to block light and generate signal changes, and calculates particle size and concentration through the number and amplitude of pulses; Microscopic counting method captures particles through a filter membrane and observes them under a microscope, which can analyze morphology but takes a long time; The dynamic image rule combines high-speed photography and image processing to provide more detailed particle feature data.
Insoluble particle detectorThe main application areas include:
1. Pharmaceutical industry: detect particle contamination of injection solutions, sterile powders and other drugs to ensure compliance with pharmacopoeia standards (such as Chinese Pharmacopoeia CP-0903);
2. Medical devices: Evaluate the particle risk of implanted devices and drug packaging materials (such as pre filled syringes) to avoid complications such as thrombosis or inflammation;
3. Multi industry liquid testing: covering fields such as food and beverage, electronics industry, and cosmetics, used for quality control and pollution assessment.
The development of technology tends towards intelligence, such as corrosion-resistant flow path design that can detect organic solvents, and dual laser technology to improve detection accuracy. Attention should be paid to calibration (every 6 months) and sampling volume control during operation to ensure accuracy.
