The DeLisle laboratory is located in Portage, Michigan. It was established in 1985, and has strived to meet and exceed our client's expectations. DeLisle asbestos bulk sample analysts are trained by the McCrone Research Institute and have over 24 years of experience in the analysis of asbestos bulk samples.
DeLisle participates in an external Round Robin AIHA Proficiency Analytical Testing (PAT) program for analysis for airborne fiber samples.
All of our Phase Contrast Microscopy analysts have successfully completed a NIOSH-582 equivalency course to analyze air samples. All analysts participate in an inter-laboratory and external round robin samples exchange program for quality assurance.
DeLisle's laboratory can perform a variety of analysis from;
- Asbestos in Building Materials
- Fine Particle/Fiber Analysis
|
PHASE CONTRAST MICROSCOPY (PCM)
Phase contrast microscopy (PCM) is used to determine fiber concentrations in air. All asbestos analyses are performed in strict compliance with the NIOSH 7400 Method, counting rules A. DeLisle's PCM laboratory participates in the AIHA Proficiency Analytical Testing program. |

POLARIZED LIGHT MICROSCOPY (PLM)
Polarized Light Microscopy (PLM) is an optical microscopic technique that enables the testing and identification of minerals and materials including asbestos by determining the various optical properties of the particles being examined. Asbestos minerals can unequivocally be identified through the use of this type of microscopic analysis by a highly trained analyst.
