Transfer technique for electron microscopy of membrane filter samples.

摘要: A procedure is described for the quantitative transfer of fibers and particulates collected on membrane filters to electron microscope (EM) grids. Various Millipore MF (Millipore AA, HA, GS VM; 0.8, 0.45, 0.22 0.05 µm mean pore size) have been used with success. Observed particle losses not size dependent exceeded 10%. With (glass or asbestos) as media this observed loss approximately 3%.
