High-Capacity In-Stack Particle Sizing for PM10 & PM2.5 Emissions
Overview
The Apex Instruments Method 201A Sampling System is designed for in-stack particle sizing applications, providing accurate determination of PM10 and PM2.5 emissions.
Unlike cascade impactors, Apex non-threaded cyclones offer higher particulate collection capacity—up to 10 grams per stage. This enables:
✅ Larger sample collection for gravimetric and chemical analysis
✅ Longer sampling times for more accurate averaging
✅ Reduced reloading at each sample point
The Apex Cyclone System is also ideal for particle size research testing, offering precise and efficient performance.
Key Features & Specifications
- Non-threaded cyclone assembly fastened with bolts for:
- Enhanced stability
- Easy repair compared to traditional threaded cyclones
- Break-away assembly with expendable stainless-steel bolts:
- Prevents seizing during sampling
- Allows PM recovery without damaging cyclone flanges or contaminating the sample
The Method 201A Sampling System provides a superior alternative for in-stack particle sizing and emissions monitoring.
