[Method of computing the volumetric concentration of elements in thin tissue sections based on x-ray spectral microanalysis data].

: For calculating the concentration of elements in terms of millimoles per litre according to the quantitative X-ray microprobe procedure (Warner, Coleman, 1973), the mass thickness is to be known. However, it can be omitted for thin tissue sections which may be considered as thin film. In the present work the limits of such thin sections are determined. In addition, the calculated corrections (Burovina, Pivovarova, 1978) are checked experimentally.
