Asbestos Department

Asbestos Department

CEI is a fully accredited NVLAP and AIHA-LAP, LLC laboratory providing identification by PLM, TEM, and PCM test methods. CEI is one of the nation’s largest asbestos laboratories with 30 full-time employees and over 25 years of experience in the industry. Our Asbestos Departments are staffed with experienced analysts and managers who can easily process over 1,000 samples each day. At CEI, our focus is on providing clients with fast, accurate, and legally defensible data for every project. We take special pride in meeting our client’s turnaround time nearly 100% of the time, a reflection of our commitment to customer service.

Testing is available 24/7, 365 days per year.

Polarized Light Microscopy (PLM)

  • PLM Analysis 1
  • PLM Analysis 2
  • PLM Analysis 3

PLM analysis, including PLM Point Count and PLM Gravimetric, are the most common EPA approved test methods for asbestos identification in bulk materials. However, some building materials, like vinyl containing floor tiles (VCT) may have fibers that are too small to be identified by PLM.

Transmission Electron Microscopy (TEM)

  • TEM Analysis 1
  • TEM Analysis 2
  • TEM Analysis 3

TEM provides high resolution “state of the art” analysis for asbestos identification in both bulk and airborne. In some cases, TEM analysis is mandated by State or Federal regulation, and TEM is recommended by EPA for testing VCT.

Phase Contrast Microscopy (PCM)

PCM airborne fiber counting is widely used to meet contractor OSHA requirements and final air clearance in some public buildings. However, PCM analysis by the NIOSH 7400 Method does not identify asbestos fibers or fibers less than 0.25 microns in width.
