Determination of the mass concentration of quartz in small biopsy specimens for clinical diagnostic purposes often cannot be performed by x-ray diffraction and light microscopy. A technique utilizing transmission electron microscopy (TEM) was used to determine the quartz concentration in a human lung specimen taken from a patient suspected of having silicosis.The sample was prepared for examination by low temperature incineration in an oxygen plasma. The inorganic residue was suspended in 0.5 percent Parlodion in amyl acetate. Grids were coated with the sample suspension and subsequently shadowed with a thin film of carbon. Standard quartz particles were prepared in a similar manner.
