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.
