Methods for asbestos analysis differ in complexity and are chosen based on data needs. Simplistically, a trained technician identifies a number of samples visually under a microscope. Observed fibers are viewed at different magnifications and counted consistent with the rules and capabilities of each method. Depending on the method, outcomes could reveal the type and amount of asbestos present and the dimensions of every counted fiber as well.
When taking samples of bulk materials for the intention of Asbestos Analysis Labs in Chennai, there are specific precautions that must be taken by the sampler in order to keep away from needless exposure to fibers which might prove to be asbestos.
Without analysis by a microscope, asbestos presence in materials could not be determined so for the most part the test kits are simply 'sampling' kits. The real analysis is made in the lab. The most common form of lab analysis to test for asbestos is done with a polarizing microscope. It is a very powerful and versatile instrument in the identification of materials. It is a main tool in a number of scientific fields, and can sometimes be the best alternative over more costly technologies.
For instance, in routine asbestos analysis the polarizing microscope was determined to be more accurate and much more cost effectual than the other high-tech choices that were first examined, like x-ray diffraction and scanning electron microscopy. It is a powerful tool with a lot of applications.
Asbestos testing is needed, for the reason that you can't tell whether a material contains asbestos only by looking at it, unless it is labeled. If uncertain, treat the material as if it contains asbestos or have it sampled and analyzed by a trained professional. A professional ought to take samples for analysis. A professional knows what to look for, and as there may be an increased health risk if fibers are released. However, asbestos testing must always be made by an expert.
