Polarized light microscopy is one of the most commonly used techniques for the analysis of large asbestos samples. It is a process that is based on optical mineralogy in that the identification of asbestos depends on the optical properties of the bulk samples when treated with certain dispersion staining liquids. These bulk samples are usually collected by an EPA accredited inspector during a routine asbestos survey. If you are looking for professional asbestos testing services, look no further than Iris Environmental Laboratories. We offer professional PLM lab testing services at
Understanding Polarized
Light Microscopy (PLM)
Polarizing light microscopy is a technique that allows you to evaluate the three-dimensional structure and composition of anisotropic specimens. Polarized light has waves that vibrate in one direction and this light is used in polarized light microscopy to improve image quality while examining anisotropic materials.
In polarized light microscopy, a polarizer intervenes between the sample and the light source, converting the polarized light source to a plane polarized light. This polarized light lands on a double-refracting specimen that produces two waves that pass through the specimen in various phases. An analyzer then combines these waves using destructive and constructive interference, leading to the development of a high-contrast image.
Why Do You Need Polarized Light
Microscopy (PLM) Services?
If you would like to know the amount of asbestos in your property or building materials, polarized light microscopy is the most suitable method for you. PLM tests will indicate the total percentage of asbestos in a specific material after analysis. This will help you know whether the level of asbestos is within the Environmental Protection Agency standards and regulations for hazardous and toxic materials. PLM is also highly sensitive therefore produces more accurate and highly-contrasted images.
