Samples <br />were observed at 30X and suspect fibers were picked from the bulk samples and observed under <br />polarized light microscopy. The fibers were then evaluated under crossed polars for extinction angle, <br />sign of elongation, and morphology. Dispersion staining techniques using different Cargille liquids <br />and observing colors at two different orientations of the crystal were then performed. <br />Analysis was performed according to EPA method 600/R-93/116. This method detects asbestos in <br />volumetric concentrations of 1 % or greater. Bulk samples were checked for the following types of <br />asbestiform minerals: chrysotile, amosite, crocidolite, anthophyllite, and tremolite-actinolite. <br />Laboratory Manager, <br />1/(6,4 <br />Melissa Cook <br />Limit of Detection: 1 %. Some samples may contain asbestos fibers in quantities below the PLM detection limit of 1 %. Results are based on <br />field sampling information provided by the client and are only valid for samples tested. Samples are stored for 30 days unless other <br />arrangements are made by the client. Samples received in good condition unless otherwise noted.
