Asbestos Testing

ASBESTOS LABORATORY SERVICES

Accredited by the National Institute of Standards and Technology, National Voluntary Laboratory Accreditation Program (NVLAP) for bulk asbestos analysis (Lab Code: 101221-0).  Fully accredited by the American Industrial Hygiene Association Laboratory Accreditation Programs, LLC (AIHA-LAP, LLC) for PCM analysis (Lab ID#: 100951). 

 

Bulk Material Testing (PLM)

 

Using Polarized Light Microscopy (PLM), Micro Air, Inc. can identify asbestos in a variety of bulk building materials, including loose-fill insulation, acoustic and thermal sprays, pipe and boiler wraps, plasters, flooring products, roofing materials, and cementitious products.  Quantification is done using visual area estimation.

 

Method of Analysis: Polarized Light Microscopy (PLM) with Dispersion Staining using the Test Method for the Determination of Asbestos in Bulk Building Samples, EPA Method/600/R-93/116 (1993). 

 

Turnaround Times Available: 2-Hour, Same Day, 24-Hour, 48-Hour, 3-5 Day

Bulk Material Testing (400 Point Count)

 

Using Polarized Light Microscopy (PLM), Micro Air, Inc. can identify asbestos in a variety of bulk building materials, including loose-fill insulation, acoustic and thermal sprays, pipe and boiler wraps, plasters, flooring products, roofing materials, and cementitious products.  Quantification is done by point counting.  This is typically used for samples with lower concentrations of asbestos.

Turnaround Times Available: 24-Hour and 3 Day

 

Dust Characterization (PLM)

 

Micro Air, Inc. uses Polarized Light Microscopy (PLM) to identify common particles that are typically large enough to be seen by the naked eye.  Such particles include cellulose and synthetic fibers, asbestos, fibrous glass, dust mites, carbonaceous materials (including soot and char), mold spores, pollen, arthropod fragments, major minerals and skin fragments.  Using reference standards, Micro Air, Inc. is able to determine what the likely material may be but cannot pinpoint the actual source of the contamination.    Sampling of bulk materials is typically performed by the glove bag technique.  Dust is commonly collected by micro-vacuuming; or wipe sampling with a 4x4 inch piece of baby wipe, (no aloe or cleaners).  In addition, dust characterization can be analyzed under Phase Contrast Microscopy (PCM) using a tape or direct spore trap sample in the same manner described above.

Turnaround Times Available: 3-5 Day

 

Asbestos and Other Fibers in Air Testing (PCM)

 

Using Phase Contrast Microscopy (PCM), Micro Air, Inc. provides an index of airborne fibers using the NIOSH 7400 Method.  Typical analysis uses the 7400 Method’s “A” rules and is primarily used for estimating asbestos concentrations; though it does not differentiate between asbestos and other fibers.  In addition, Micro Air, Inc. can use an alternate set of counting rules from the NIOSH 7400 Method that is more appropriate for the measurement of specific non-asbestos fiber types such as fibrous glass.

 

Method of Analysis: NIOSH 7400 Method, Issue 2: 15 August 1994

 

Turnaround Times Available:  2-Hour, Same Day, 24-Hour, 48-Hour, 3-5 Day
