Air Sampling

Air Sampling for Microscopic Examination

Air Samples operates on the well established principle of inertial impaction. Particles in the air stream are accelerated as they approach the tapered inlet opening and drawn through a small slit aimed directly at a glass slide. This glass slide contains a sticky and optically clear sampling media which can permanently collect and hold particles. As the particles come through the slit, the air velocity forces the particles to impact into the sampling media, while the air stream makes a sharp 90o turn and proceeds around the slide and out of the cassette.


Air sampling is a unique sampling cassette specifically designed for the rapid collection and quantitative analysis of a wide range of airborne aerosols. It collects both viable and non-viable particulate such as mold spores, pollen, insect parts, skin cell fragments, fibers (asbestos, fi berglass, cellulose, etc.) and inorganic particles.

  • Indoor Air Quality: Mold spores, pollen, insect parts, dust mites, skin cell fragments, plant fragments, dust, fibers, combustion emissions, etc.
  • Home Inspection: Mold Contamination before of after real estate transactions.
  • Flood Restoration: Evaluation of mold spore contamination before, during, and after remediation.
  • Allergy Testing: Mold spores, pollen, insect parts, dust mites.
  • Clean Room Monitoring: Evaluation of low airborne dust and contaminants from personnel (skin cells, clothing fi bers, cosmetics, etc.)
  • Fiber Analysis: Asbestos, fi berglass, cellulose, ceramics, etc.
  • Stack Emissions: Fly ash, inorganic dust, etc.


  • Provides excellent detection limits over conventional filter sampling utilizing filter cassettes.
  • Eliminates sample loss to cassette walls known to occur with filter samples from vibration or static charge during sampling and shipment.
  • Eliminates the need for direct handling or preparation of collection media or microscope slides in the field.
  • Eliminates potential cross-contamination between samples and during shipping that may occur with other laboratory specimen types or devices.
  • Unique optically transparent and smooth collection media allows direct staining and examination by bright field, dark field, and phase contrast microscopy!!
  • Sampling media is compatible with a wide range of biological stains and refractive index oils allowing for direct quantitative analysis of biological and inorganic particles.
  • Generally will work with virtually any kind of sampling pump.

Spore Trap Analysis - Mold

Analysis includes identification to genus or group of all fungi present, quantification to spores/m3, and a general assessment of background debris.

Spore Trap Analysis - Other Particles

Analysis is available as a supplement to the standard "Spore Trap analysis" and consists of identification of other particulates including quantification to particles/m3 and a general assessment of background debris.
