This method uses x-ray powder diffraction to perform analysis of percent chrysotile asbestos in bulk samples. Note the precaution that since asbestos is a human carcinogen, it should be handled in a hood. NIOSH methods 7402 (Asbestos by Transmission Electron Microscopy) and 9002 (Asbestos by Polarized Light Microscopy) are also useful for positive identification of asbestos.
Analysis Type (Application Method): X-Ray powder diffraction
