Method for determining the concentration ratio of two elements of a substance from the ratio of intensities of two spectral lines of these elements in a plasma of this substance.

摘要

IS PROVIDED A method for determining concentration ratios CAB two elements, A, B, of a substance FROM CURRENT RELATIONSHIPS IAB TWO SPECTRAL LINES OF THESE ELEMENTS IN A PLASMA of this substance. IN THIS PROCEDURE IS MEASURED, besides the IAB intensity ratio IC1,2 the intensity ratio of two spectral lines 1 and 2, OF AN ITEM C, LIFTING WITH DIFFERENTIAL E1 and E2 ENERGIES AND DETERMINED Under the EQUATION (1) of the CAB concentration ratio. CONSTANT K is precomputed, FROM A LIST OF KNOWN CONCENTRATION C''AB AYB ELEMENT OF A SUBSTANCE approvable AND INTENSITY RATIOS APPLICABLE, MEASURES IN THE SPECTRUM OF PLASMA I''AB E IC1,2, A TENOR Equation 2 (2). MUST ALSO HAS AN AREA tner EVALUATION LIMITED IAB, I''C1,2 And C''AB.
