Cleanroom (Ⅱ) — Operational Monitoring Guide: 1 CFM & Point Strategy
This article explains why online cleanroom monitoring favors 1 CFM (28.3 L/min) and how to plan representative sampling points using a practical Room → Process → Risk method. Larger minute-volume improves detection probability for small particles and shortens response time for transient spikes. We cover engineering essentials—isokinetic probes, optimized tubing, and routine calibration—to keep high-flow data stable. A “good-enough” alarm framework (baselines, SPC limits,... -
Cleanroom Series (Part 1)
This article explains the cleanroom shift from spot checks to continuous, in-operation particle monitoring. It outlines why spot checks miss dynamic spikes and suffer from small sampling volumes and broken evidence chains. It then shows how continuous monitoring delivers earlier detection, better explainability, and audit-ready data. Readers learn the essential monitoring loop—Measure → Alert → Verify → Investigate → CAPA—plus practical ways to avoid...
