Carbon in Cast Iron


    SPECTRO Analytical Instruments has developed a new method for the determination of carbon in cast iron that combines the accuracy of traditional combustion analysis with the speed and ease-of-use of optical emission spectroscopy (OES) or arc spark OES. Integrated into the SPECTROLAB and SPECTROMAXx systems, this innovative spark OES technology enables samples with free graphite to be precisely identified and, if at all possible, analyzed. Here, the results achieved are comparable to those found with time consuming and expensive combustion analysis technology.

    The Arc Spark OES Method – Better Technology for Superior Performance

    With this new arc spark OES method, SPECTROMAXx and SPECTROLAB instruments are able to monitor the carbon signal during the pre-spark phase and to recognize the existence and proportion of free graphite in the sample. With this information, it is possible to decide whether a value for the carbon can be determined or not. If the graphite content is too high, the carbon concentration is replaced by a “warning.” As always: the better the quality of the sample being analyzed, the better the quality of the result.
