Simultaneous determination of oxygen and nitrogen in iron and steel by spark-source mass spectrography

Abstract:
A conventional technique has been developed for the simultaneous determination of oxygen and nitrogen in iron and steel by spark-source mass spectrography in the range of 2-400 ppm with a precision of 20%. The instrumental background can be reduced by cryosorption pumping and sample cooling. The adsorbed oxygen on the surface of the sample is easily eliminated by presparking to exhaust the surface concerned. A difference in matrix effect in oxygen determination was observed between iron and steel.
