EMSL Analytical, Inc. provides laboratory services at a local Naturally Occurring Asbestos (NOA) and Erionite project in the southwestern United States. Work performed over the past two years includes PLM and TEM analyses on numerous soil samples. EMSL also provide technical support as the scope of work changed and advise on tests and analytical techniques that would provide the best results. In this case the Fluidized Bed Asbestos Segregator (FBAS) was selected as the best approach. This analysis predominantly focused on NOA and Amphibole mineral speciation.
