In this 5-day introductory course students will learn to identify asbestos fibers, their substitutes and look-a-likes through a review of the basic theory, as well as inclusion of more advanced methods. The course emphasizes refractive index measurements; interpretation of dispersion staining colors; and alternative dispersion staining methods (critical darkfield and phase/pol). Also included are various sample preparation techniques including gravimetric methods, small particles, complex matrices and chemically and heat-altered samples. Students must analyze complex samples and demonstrate proficiency with more advanced sample preparation and identification techniques.
