Asbestos identification is detennined by the morphology, visual Selected Area Electron Elemental Analysis using an Energy Dispersive X-ray Analyzer G2DAX). is calcutated by taking the wumber of asbestos structures and dividing by the area analyzed. Air concentration is calculated by omitiplying these caiculatians can be found on the Asbestos Count Sheet. relates only to air fiber content, When semples are submitted by an outside agency for analysis, Enviroscience. can only guarsatec the roncentration.
