摘要：

Spark ablation was applied as an inexpensive technique for direct sample introduction in elemental analysis by inductively coupled plasma mass spectrometry (ICP-MS) with restriction to conducting samples. For these investigations, a commercial spark ablation system developed for application in ICP atomic emission spectrometry was coupled with a laboratory-built ICP-MS system. The spectra show only small contributions from disturbing polyatomic species; in particular, argides can be neglected. In the analysis of steel, detection limits below 100 ng g-1 were determined; the precision was about 3%. A calibration procedure was applied to a set of steel standard reference materials. The relative sensitivity factors correspond to values obtained by glow discharge MS with identical MS equipment.
