Abstract
A spectroanalytical method includes the steps of exciting material to spectroemissive levels, dispersing radiation from the excited sample material into a spectrum, positionally locating a reference constituent of the excited material in the spectrum, the reference constituent having a known wavelength offset from an element of interest in the sample material to be analyzed, and then shifting the known wavelength offset by an essentially hysteresis free mechanism and making an analytical measurement at that wavelength offset position of radiation produced by a spectrum from sample material that has been excited to spectroemissive levels.
