Environmental Analysis Associates, Inc. (EAA) is led by trusted experts in particle analysis and indoor environmental testing.
Comprehensive Dust Characterization & Analysis
Identify, quantify, and understand what’s really in your air and on your surfaces with lab-backed clarity.
Environmental Analysis Associates, Inc. (EAA) is a nationally recognized leader in dust characterization and indoor air particle analysis, offering one of the most advanced microscopy-based testing services available in North America. We are one of the few laboratories in the country specializing in both Optical Microscopy and Scanning Electron Microscopy (SEM/X-ray analysis) for evaluating airborne and surface dust contaminants.
Our expertise goes beyond laboratory equipment. With decades of field experience and consulting insight, EAA provides not only highly accurate testing—but also expert interpretation of what the results mean for your space, your health, or your legal case. Our team supports a wide range of investigations including HVAC system contamination, post-fire particle exposure, occupant-generated dust evaluation, and industrial hygiene assessments.
EAA’s dust testing services identify and quantify a variety of indoor particle types, including:
We also offer DUST PROFILE™, our proprietary percentile-based interpretation system that compares your building’s particle concentrations against a national database of indoor environments—helping you understand what’s typical, atypical, or elevated.
EAA is led by Mr. Daniel M. Baxter, inventor of the Air-O-Cell®, the most widely used airborne mold and dust sampling cassette in the country. His leadership and innovation continue to set the standard in forensic-level indoor environmental analysis.

Dust characterization testing identifies the types of particles present in indoor environments—such as skin cells, mold spores, fibers, soot, and corrosion particles. Understanding what’s in your dust helps pinpoint contamination sources, evaluate air quality, and guide remediation or legal strategies.
EAA uses a combination of Optical Microscopy and advanced Scanning Electron Microscopy (SEM) with X-ray analysis. This dual-method approach allows us to classify particles by size, shape, chemistry, and origin—providing a complete picture of indoor environmental conditions.
EAA’s testing goes beyond raw data. We provide expert interpretation through our proprietary DUST PROFILE™ system, comparing your results to a national database of real-world buildings. This gives you clear context and helps identify whether your dust levels are typical or elevated.
Our dust characterization services are trusted by environmental consultants, industrial hygienists, attorneys, insurance professionals, and property managers. Whether you’re investigating indoor air complaints, preparing a legal case, or verifying HVAC system performance, EAA delivers the insight you need.
