Enterprise Dust & Particulate Protocol
Understanding the core operating principles of dust measurement ensures compliance with strict EPA, OSHA, and ISO mandates. Selecting the appropriate technology prevents regulatory fines and protects occupational health.
Light Scattering (Optical)
Best For: Real-Time Instant DataUses a laser beam to illuminate particles. Scattered light is collected by a photodiode, producing a signal proportional to particle concentration. Offers immediate trending data without waiting for lab analysis.
Gravimetric Sampling
Best For: Regulatory ComplianceThe absolute standard. Pumps a known volume of air through a pre-weighed filter. The filter is re-weighed in a laboratory. It is the only legally defensible method for official EPA/OSHA compliance logging.
Beta Attenuation (BAM)
Best For: Continuous AmbientParticles are collected on a continuous filter tape. A Carbon-14 beta source measures the attenuation (absorption) of beta rays through the dust spot. Highly accurate and fully automated for weeks.
TEOM (Tapered Element)
Best For: High-Precision MassUses a vibrating glass tube. As dust accumulates on a filter attached to the tube, the oscillation frequency changes. This provides true continuous direct mass measurement, uninfluenced by particle color.
