Determination of sulphur and nitrogen in steel by glow discharge spectrometry.

Martin Lundholm

It was previously shown that very advantageous results for the precision of S and N at low levels in steel were obtained when this was investigated by running reference samples on a spectrometric system using a specially developed glow discharge lamp as the spectral source. The main objective of the present project was to investigate if the high precision obtained could be repeated also for lollipop samples taken from the steel production process.
