  2. What Are We Measuring And Why? • Particles suspended in air that can have a significant effect on a person’s health and welfare. • In terms of protecting human health, we are measuring particles of a size range that penetrate deep into lungs.

  3. PM10 (10 µm) PM2.5 (2.5 µm) Why Size Matters PM10/ PM2.5 Hair cross section (60 µm) Human Hair (60 µmdiameter)

  4. Things That All Particulate Samplers Have In Common • Size-selective sampling inlet (which separates out large dust particles from small particles that penetrate deep into lungs) • Filter or electronic sensing device • Electronics to maintain precision flow control • Vacuum source (vacuum motor or vacuum pump)

  5. Particle Sampler Block Diagram

  6. Types Of Measurement Methods • Filter Based Methods • Automated Electronics-Based Methods

  7. Differences In Method Characteristics • Filter-Based Measurements • Requires laboratory analysis • Typically provides 24-hour avg value • Results are accurate and precise • Used for EPA-type measurements • Electronics-Based Measurements • Provides real-time results or near-real-time results • More portable (most of the time) • Good indicator of pollutant levels • Not as accurate

  8. Types Of Filter-based Samplers • PM10 Hi-Volume Sampler • PM10 Low-Volume Sampler

  9. Partisol 2000 – Filter Based Low-Volume Sampler

  10. Examples Of Automated Electronic Monitors Dust Trak™ Laser - Light Scattering Sensor Beta Attenuation Monitor (BAM)
