Asbestos fibers are very small (often <0,0005 mm in diameter). In order to quantify the asbestos concentration, the sample has to be studied at 1000–2000 times magnification. The microscope is equipped with an energy dispersive sector, which allows the chemical compostion of the fibers to be determined.
What kind of microscope can see asbestos?
There are two different types of electron microscope used for asbestos analysis: Scanning Electron Microscope (SEM) and Transmission Electron Microscope (TEM). Scanning Electron Microscopy is useful in identifying minerals.
What are the characteristics of asbestosis?
Asbestosis is long-term inflammation and scarring of the lungs due to asbestos fibers. Symptoms may include shortness of breath, cough, wheezing, and chest tightness. Complications may include lung cancer, mesothelioma, and pulmonary heart disease.
What is polarized light microscopy asbestos?
Polarized Light Microscopy (PLM) is used for the determination of asbestos in bulk building materials and other samples such as soil and rock. Silicate minerals, including asbestos, have a crystal lattice that interacts with the light rays of the microscope.
