Evaluation of Spectrochemical Data Using Digital Techniques
by N. R. D. Åslund, B. T. Cronhjort
This paper describes how a digital computer was used in combination with an emission spectrometer to determine chemical compositions of some steels. A mathematical model describing the relations between the composition and the intensities of the spectral lines was derived and experimentally tested. Both overlapping and matrix effects were considered. The computer was also used to calibrate the instrument.
