ABSTRACT:
A spectroanalytical system with radiation dispersing apparatus having structure for dispersing radiation into a spectrum for concurrent application to a plurality of exit ports; a plurality of radiation sensor channel circuits, each circuit being optically coupled to a corresponding exit port for monitoring radiation at that exit port; sample excitation apparatus for exciting sample material to be analyzed to spectroemissive levels for generating a beam of radiation for dispersion by the dispersion structure; and controller structure for triggering the excitation apparatus to excite the sample material and for generating a gating interval by the channel circuitry for accumulating radiation data during an interval that commences subsequent to application of maximum energy to the sample by the excitation apparatus.
