Abstract

The determination of gas-forming impurities in samples of low-alloyed copper alloys of the Cu–Cr and Cu–Cr–Zr systems is carried out. The content of sulfur and carbon was determined by the method of combustion in an induction furnace of a gas analyzer with subsequent detection in the infrared cell of the spectrometer, and to determine oxygen and nitrogen, the method of reducing melting in a flow of an inert carrier gas was used, followed by the detection of oxygen in the infrared cell and nitrogen in the conductometric cell of the gas analyzer.
