  • Method for determining carbon in cast iron
    Patent number: 8976350
    Abstract: A method of determining the carbon content of an iron alloy may include starting of the measurement of a sample in a spark spectrometer, creation of a plasma in a pre-sparking phase, detection and recording of an intensity signal for the carbon, calculation and cutting out of an unstable plasma phase, calculation of an excessive rise in the carbon signal, and calculation of the content of dissolved and undissolved carbon.
    Type: Grant
    Filed: February 17, 2011
    Date of Patent: March 10, 2015
    Assignee: Spectro Analytical Instruments GmbH
    Inventors: Roland Van Driel, Bruno Van Stuijvenberg
