Performance of a glow discharge mass spectrometer for simultaneous multielement analysis of steel
The analysis of steel has been performed on a previously described laboratory prototype of a new glow discharge mass spectrometry (GDMS) system equipped with a quadrupole filter in order to study its analytical performance. Operational parameters of the discharge have been optimized and seven NBS standards and one USS standard have been analyzed. A weighted regression has been applied for calibration. The results include sensitivity factors and precision data for 26 elements. In multielement analysis, the detection limit was about 0.1 mol/mol while single-element determination was possible at a 5 times lower detection limit. Analysis results for two test samples with 30 elements each agree within 10% of the certified values. Consequently the method proves to be a valuable tool for simultaneous multielement trace analysis of solids.
