Microscopical Identification of Asbestos (1608A), October 16-20, 2017

  Register for this course  / $1,675.00

“This class helped with the technical aspect of asbestos analysis” — Meredith O.

“I have a much better understanding of the mechanics and practices involved in this field” — Marc W.

“I am much more comfortable with the scope and Infinitely more familiar with asbestos fibers than I was a week ago.” — Student review


Using polarized light microscopy (PLM), students study crystallographic and optical properties of asbestos minerals, the various substances likely to occur (and often confused) with asbestos and the procedures for sample preparation and fiber identification. Serpentine (chrysotile) and amphibole (amosite, crocidolite, tremolite, actinolite, and anthophyllite) asbestos varieties are included.
