PARTICULATE MATTER (DUST) MONITORING



STANDARDS FOR

PARTICULATE MATTER (DUST) MEASUREMENT

Particulate matter monitoring (Dust) Automated Measuring System (AMS) is a measuring

system permanently installed on site for continuous monitoring of dust emissions.

Standard Reference Method (SRM) is a method described and standardised to define

an air quality characteristic, temporally installed on site for verification purposes.

For the purpose of EN 13284-2:2004, the SRM for particulate matter (total dust) is specified in:

low levels < 50 mg/m3 EN 13284-1:2001

high levels > 50 mg/m3 ISO 9096:2003 (20-1000 mg/m3)

PARTICULATE MATTER MONITORING AMS

MEASURING TECHNIQUES (PRINCIPLES)

Measuring techniques for particulate matter (Dust) monitoring AMS

(AMS for Dust):

1. Opacity – Light attenuation (Absorption)

2. Dynamic Opacity (Sintillation)

3. Light Scattering (Back, Side, Forward)

4. β-Attenuation (Radioactive)

5. Tribo-electric

6. Electro-dynamic

7. Oscillating Filter (Vibrating tapered element)

not used for emission measurement!

DUST IS NEVER MEASURED DIRECTLY!
