Warning Note; PLM limitation, only TEM will resolve fibers <0.25 micrometers in diameter. TEM bulk analysis is representative of the fine grained matrix materiai and may not be representative of non-uniformly o dispersed debris for which PLM evaluation is recommended (i.c. soils and other heterogenotis niaterials).
