Comparison of asbestos air samples by SEM-EDXA and TEM-EDXA / Kenneth T. Roberson, Thomas C. Thomas and Larry R. Sherman

Sumario: Because occupational air samples submitted to this laboratory for fibre counting often need to be confirmed as to the type of asbestos, random air samples were compared by a scanning electron microscope (SEM) and a transmission electron microscope (TEM) to determine if both methods yielded comparable resulsts. The results of this study revealed neither and advantage nor a disadvantage for confirmatory analyses of asbestos by either SEM or TEM. Several distinct characteristics were observed during the study
