EMS
has been analyzing samples for asbestos since 1978. EMS can
supply any level of analysis for asbestos including:
Transmission
Electron Microscopy (TEM) with selected area electron
diffraction and energy dispersive x-ray analysis for positive
identification of all asbestos structures below SEM, PLM, and PCM
resolution.
Air Samples:
- AHERA 40 CFR Part 763 for school
clearances
- NIOSH 7402 which complements NIOSH 7400
for PCM equivalent size fibers
- U.S. EPA Draft Contract 68-02-3266
authored by Yamate, etal (Level I, II and III)
- ISO 10312
Bulk, soil, urine,
sputum, lung tissue, sediment and waste water which includes
quantitative weight percent:
- EPA 600/4-83-043 and EPA 600/R-93/116
Microvacs of dust:
Drinking water for fibers greater than 10 µm in
length
Drinking water for fibers for all size fibers length
Polarized Light Microscopy (PLM) with dispersion staining for
identification of bulk material for asbestos down to 1%.
- U.S. EPA 600/R-93/116
- NIOSH 9002
- OSHA ID191
- CARB 435
- EPA 600/M4-82-020
- Point count (Gravimetric) for < >
0.1%
X-Ray
Diffraction Analysis
(XRD) for
quantification of bulk asbestos-containing materials in the 1% region
and when
fibers are too small to resolve by PLM for bulk materials
NIOSH
9000, quantitative analysis
Superfund
method for the determination of releasable asbestos in soils
and bulk materials by the elutriator method
