Asbestos AnalysisA ReviewApplied Spectroscopy Reviews

Abstract Prior to an asbestos removal the work requires first a substantiation, an identification, that asbestos is indeed present. This is known as a bulk analysis. Microscopical methods, particularly polarized light microscopy, can be used to measure the physical properties of fibers in the sampled material to identify and substantiate the presence of asbestos.
