Samples were observed <br />at 30X and suspect fibers were picked from the bulk samples and observed under polarized light microscopy. The <br />fibers were then evaluated under crossed polars for extinction angle, sign of elongation, and morphology. <br />Dispersion staining techniques using different Cargille liquids and observing colors at two different orientations <br />of the crystal were then performed. <br /> <br />Analysis was performed according to EPA method 600/R-93/116. This method detects asbestos in volumetric <br />concentrations of <1% or greater. Bulk samples were checked for the following types of asbestiform minerals: <br />chrysotile, amosite, crocidolite, anthophyllite, and tremolite-actinolite. <br /> <br /> <br /> <br /> <br />Laboratory Manager, <br /> <br /> <br />Joshua Kranz
