Abstract
A highly accurate, rapid scanning monochromator type of spectroanalysis system employs a source of the plasma emission type, a filtering monochromator, and a resolving monochromator. Each monochromator has a dispersing element and the two dispersing elements are arranged to be moved simultaneously but at different rates such that the spectral order of radiation from the source as dispersed by the first dispersing element is different from the spectral order of radiation dispersed by the second dispersing element, together with selectively operable control means for moving the two dispersing elements simultaneously and at the same rate.
