Abstract: This method consists in subjecting the surface of the metal to an electrical discharge under an inert atmosphere and in simultaneously recording, as a function of time, the spectral response emitted. Before recording, the sample to be analysed is covered with an electrically conducting layer. This conducting layer is produced in situ, before the analysis, by reverse polarity electrical discharge.

Abstract: The plate cut from a quartz crystal plate (15) whose sides and its sides are optically flat and are perpendicular to the light path. The spectrum is produced by an electric arc struck between electrodes (10) enclosed in a chamber (3). A current of argon is admitted to the chamber through a pipe (8) and leaves through a second pipe (9). The light from the arc enters the vacuum spectrometer (2) through the quartz plate and falls on a diffraction grating (6). Light diffracted from the grating falls on a photocell (7). A vacuum pump (4) of normal pattern is connected to the spectrometer by a pipe (4).

Abstract: Contents of elements in metals, e.g. aluminum in steel, which are present as a total quantity in an elemental/dissolved form and in a non-elemental or separated form, are determined by sparking the surface of the metal under an inert atmosphere. The spectral signal is simultaneously measured as a function of time, and a signal is obtained which initially exhibits an intensity peak, from which the non-elemental or separated element content can be concluded, and the signal then stabilizes at a stationary value from which the total content (Ct) of element can be concluded. The elemental/dissolved proportion (Cs) can be concluded from the total area (P1) below the peak, from the area (P2) under the stationary intensity measured over a time (t2-t1) and from the total content (Ct).
