Asbestos testing laboratory
Asbestos analysis methods vary in complexity and are selected based on the data requirements. Simplified, the trained technician identifies several samples under a microscope visually. Observed fibres are viewed at different magnifications and accounted for according to the rules and abilities of each method. Depending on the method, the results may indicate the type and quantity of the asbestos present, and the dimensions of each fibre counting.
When sampling bulk materials for asbestos analysis, special measures must be taken by the sampler to avoid unnecessary exposure to fibres that can be asbestos.
Without analysis of the microscope, the presence of asbestos in the materials could not be determined so that in most cases the test sequences are simply "sampling" sets. The present analysis is carried out in the laboratory. The most common form of laboratory testing for asbestos testing is carried out with a polarization microscope. This is a very powerful tool for the identification of materials. This is the main instrument in some scientific fields and can sometimes be a better alternative to more expensive technologies.
For example, in a routine analysis of asbestos, it was found that the polarization microscope is more accurate and much more efficient than other high-tech options that were first examined, for example, by X-ray diffraction and scanning electron microscopy. This is a powerful tool with many applications.
Testing asbestos is necessary because you can not determine whether the material contains asbestos and only pay attention if it is not marked. If you are not sure, treat the material as if it contained asbestos or it has been tested and analyzed by a specialist. The expert must take samples for analysis. This person skilled in the art knows what to look for, and there may also be an increased health risk when the fibres are released. However, an asbestos test should always be carried out by an expert.
