Measurement of Carbon and Sulfur in Copper Alain Salaville, Jérôme Barraqué, Application Laboratory, Longjumeau, FRANCE Keywords: copper, carbon, sulfur, EMIA 820V 1 Introduction Copper in reddish metal, it is malleable, ductile and an extremely good conductor of both heat and electricity. Copper metal is widely used for electrical wiring, water piping, and corrosion resistant parts, either pure or in alloy such as brass and bronze. Carbon and Sulphur are con- sidered as impurities, so it is important to meas- ure and check the Copper purity. 2 Instrumentation 2.1 Principle The test was performed on the model EMIA 820V. The measurement principle is shown in Figure 2. The sample is placed in a ceramic crucible in a high frequency induction furnace. The sample is heated at a programmable
