  • Standardization of spectral lines
    Patent number: 4893259
    Abstract: A method and apparatus for standardizing spectral line intensities in a spectral monochromator separate an input beam into a sample spectral line characteristic of a sample element, a reference spectral line, a standard spectral line and a background spectral band. At a first point in time an intensity I.sub.A of the sample line, a first intensity I.sub.R1 of the reference line and a first intensity I.sub.B1 of the background band are measured. At a second point in time an intensity I.sub.S of the standard line, a second intensity I.sub.R2 of the reference line and a second intensity I.sub.B2 of the background band are measured. An intensity ratio IR defined by the formula ##EQU1## is computed wherein the intensity ratio IR represents a standardized intensity of the sample line compensated for source fluctuations.
