摘要： This invention provides a quantitative determination method capable of quickly determining a mean composition of oxide type inclusions and oxygen concentration of a metallic material such as a steel by using an optical emission spectrometer alone. This method comprises the steps of (1) conducting a plurality of times a discharge operation between the metallic material and an opposing electrode in an inert gas atmosphere to obtain an emission spectrochemical spectrum, (2) selecting a discharge in which at least either the oxygen A spectrum or the oxide-forming element spectrum exceed a predetermined intensity for each discharge operation, and (3) subtracting a background from the intensity of the oxygen spectrum and/or the intensity of the oxide-forming elements in the selected discharge, accumulating the balances to obtain a cumulative spectral intensity, and executing quantitative determination by a calibration curve method.
