Traditional PLM & TEM Bulk Sampling & Analysis  Obtain all layers of material  Best suited for vermiculite bound into a material  Not designed for applications where asbestos coexists and is not bound to other material  Bound vermiculite materials have same considerations as traditional asbestos materials including fiber size and binder type when considering PLM vs. TEM, gravimetric, and point counting.  Amount of material may not be sufficient for reliable negative determination with loose fill vermiculite  Ranges of fiber size in loose fill vermiculite makes it difficult to choose only PLM or TEM
