ABSTRACT:
A method of quantitative spark emission analysis of a select element in an alloy comprising establishing a basic calibration curve which relates a spectrometer count during a given integration time period to an actual content of the select element in a standard sample of the alloy, determining an influencing factor on the spectrometer count of the select element by the presence of an influencing element in the alloy being analyzed, spectroscopically analyzing the alloy for the select element during the given integration time period and deriving an indicated content of the select element from the basic calibration curve, and adjusting the indicated content of the select element in the alloy being analyzed by the influencing factor so as to derive an actual content of the select element in the alloy.
