Abstract
Process and apparatus for real-time determination of a solid sample composition as a function of the depth within the sample. The process comprises: forming a glow discharge ( ) of atoms sputtered from an exposed area ( ) of the sample ( ) and analysing the glow discharge by optical emission spectroscopy; measuring the distance between said exposed area ( ) and a fixed reference surface ( ) and determining from the measured distance the depth of the exposed area within the sample; and correlating the determined depth of the exposed area with the glow discharge analysis. Application to material analysis.
