Abstract：Carbon is the most important element in cast iron. It therefore has to be constantly monitored during the casting process. Sample taking is critical, too slowly chilling produces graphite inclusions. However, it is well known that spark emission spectrometers need completely graphite-free samples to produce accurate results. The reasons for this requirement are investigated and discussed. Finally the principles and capabilities of a new carbon determination method are described. This method improves the accuracy of the carbon determination in suboptimal cast iron samples, and indicates if poorly taken samples are measured.
