Air Sampling for Asbestos and Fibers
- Asbestos and Other Fibers by Phase Contrast Microscopy (PCM) - NIOSH Method 7400
This method is for the analysis of asbestos in air by Phase Contrast Microscopy. Results are reported as fibers per cubic centimeter and depend on the volume of air sampled. PCM analysis is not asbestos fiber specific and will count all fibers meeting the methods criteria for fiber determination.
- Appendix A to Subpart E of Part 763, Interim Transmission Electron Microscopy (TEM) Analytical Methods
Mandatory, Nonmandatory and Mandatory Sections to determine completion of response actions. This method is for the analysis of asbestos in air by Transmission Electron Microscopy. Results are reported as structures per square millimeter and are specific for the determination of asbestos fibers present in the sample. This procedure is typically required in Schools K-12 after completion of an asbestos abatement project, for final re-occupancy criteria.
Bulk Sampling for Asbestos
- Polarized-Light Microscope (PLM), NYS DOH ELAP 198.1
This is the method for the analysis of asbestos in bulk materials by Polarized-Light Microscopy.
- Polarized-Light Microscope (PLM), NYS DOH ELAP 198.6
This is the method for the analysis of asbestos in Non-Friable Organically Bound bulk materials by Polarized-Light Microscopy. This method combines the tracked gravimetric-reduction preparation of 198.4 with the PLM point-counting of 198.1.
- Transmission Electron Microscope (TEM), NYS DOH ELAP 198.4
This is the method for the analysis of asbestos in Non-Friable Organically Bound bulk samples by Transmission Electron Microscope.
- Revisions to ELAP Certification Manual for Analysis of Asbestos in Bulk Samples.
