Abstract
A spectroanalytical system with radiation dispersing apparatus for dispersing radiation into a spectrum for concurrent application to an array of exit ports; sample excitation apparatus for exciting sample material to be analyzed to spectroemissive levels for generating a beam of radiation for dispersion by the dispersing structure; the exit port array including a corresponding array of detectors including a first detector positioned adjacent a first exit port positioned to sense first order radiation from an element of interest and a second detector positioned adjacent a second exit port to sense second order radiation from the same element of interest; and processing apparatus for responding to outputs of the first and second detectors to provide a compensated output as a function of the quantity of the element of interest in the sample material.
