Particle Testing
Particle testing is a quality control process used in medical device manufacturing to check for tiny, unwanted particles that could contaminate medical products. It's like a very detailed inspection system that ensures medical devices are clean and safe for patient use. This testing is essential because even microscopic contaminants could cause problems when devices are used in healthcare settings. The process might also be called "particulate testing," "particle count analysis," or "particle contamination testing." It's a crucial part of quality assurance in medical manufacturing, similar to other cleanliness tests that ensure products meet strict healthcare standards.
