Abstract (en)
[origin: WO2011101143A1] The invention relates to a method for determining the carbon content of an iron alloy, comprising the following steps: a) starting the measurement (13) of a sample in a spark spectrometer, b) forming a plasma in a pre-spark phase, c) detecting (13) and recording an intensity signal of the carbon, d) calculating and masking (15) an unstable plasma phase, e) calculating an excess increase in the carbon signal (16, 17) and calculating the content of dissolved and undissolved carbon (18).
