Asbestos Testing

PLM  Asbestos  Testing

Polarized Light Microscopy (PLM) for asbestos in bulk samples:
EPA/600/R-93/116 Method.
Polarized Light Microscopy (PLM ) analysis is done to identify, classify and quantify Asbestos fiber concentration in bulk building materials, domestic & Industrial insulations, sprayed & non-sprayed plasters, coatings, ceiling & flooring materials, Floor tiles, caulks and adhesives.
Point  Count:
This method is used to quantify Asbestos fibers in bulk materials at a lower detection limit using PLM microscope. Point Count provides detection limit of 0.25%.
Phase Contrast Microscopy (PCM):
NIOSH 7400  Method.
PCM analysis is performed to measure fiber concentrations in Clearance, Personal and Ambient air samples during and after abatement.


We typically conduct the following analyses:

  • Bulk ID
  • Bulk Point Count
  • Fiber Count
  • Wipe/Vacuum Wipe

Indoor Air Quality Analyses:

  • Formaldehyde
  • Volatile Organic compounds (VOC) down to ppb levels
  • Pesticides in Air
  • Airborne Mold and Bacteria
  • Tape and Bulk Sample Analysis for Mold
  • Total and Respirable Dust
  • Airborne Mold and Bacteria
  • Airborne and Bulk Asbestos Analysis
