Transmission electron microscopy is preferably used for enhanced accuracy when carrying out air sampling of asbestos under an O&M program. While Phase contrast microscopy (PCM) is often employed for screening and for personal analysis of air sample, the caveat with the latter is its relative inability to efficiently differentiate asbestos from other particulate fibers which can be detected in air samples. Further, PCM analysis is established to be inaccurate in detecting thin asbestos fibers . It also doesn’t count short asbestos fibers which can be present in high concentrations when asbestos containing materials are disrupted. Thus, the comprehensive and reliable report derived using Transmission Electron Microscopy makes it more preferred for owners adopting supplemental air monitoring in their scheduled asbestos management program.
