Asbestos-gravimetric point count
Description: The analysis includes a detailed and very labor-intensive testing of bulk building materials for its organic components, inorganic acid-soluble and insoluble components and asbestos concentration based on 400 point counts (EPA 600/R-93/116). This is a detailed and more labor-intensive technique for estimating asbestos and other components in a building material and is less subjective than a visual estimate. This methodology, which has a detection limit of 0.25%, increases the accuracy and precision of the asbestos concentration determined in a sample. The report will express the percentage of the different asbestos fibers detected based upon the 400 point counts and also provide a percentage concentration of the organic, inorganic acid-soluble and insoluble components in the whole sample.
Sample types: Bulk sample, Dust sample, Soil sample
Available turnaround: Standard
