Fecha de publicación: | 1995 | Editor: | Royal Society of Chemistry (UK) | Citación: | Journal of Analytical Atomic Spectrometry 10: 859- 863 (1995) | Resumen: | A method for the direct elemental analysis of low-alloyed steels is described. Spark ablation coupled with excitation in a 1.5 kW argon inductively coupled plasma was applied to the direct determination of Mn, Si, P, Al, B, Co, Nb, V, Zr and Sb in low-alloyed steels by mass spectrometry. For aerosol production, a medium-voltage spark at a high repetition rate (500 V, 400 Hz) was used. A cyclone device was designed to control the aerosol particle size; with this system the total amount of material reaching the plasma is low (about 4 μg min -1) and a more uniform particle size distribution is achieved, thereby improving the precision of the measurements and preventing deposition of material in the torch injector and sampling cone. Particles re-collected downstream of the cyclone device were mostly spherical in shape, with a particle diameter of less than 1.0 μm. When using optimized operating parameters, and a low abundance iron isotope (58Fe) as an internal standard, relative standard deviations at concentration levels of ten times the detection limit were below 2.5%. Detection limits (3s) for Nb, V, Zr, Mn, Co, Al and Sb ranged from 0.08 to 0.32 μg g-1; for Si, B and P, detection limits were 1.5, 2.1 and 2.5 μg g-1, respectively. These values are comparable to those obtained for continuous-flow sample aspiration of a 0.05% m/v Fe matrix solution. The technique was applied to the analysis of the Bureau of Analysed Samples certified reference materials SS-456/1 to SS-460/1, carbon steels (residual series). | Versión del editor: | http://dx.doi.org/10.1039/JA9951000859 | URI: | http://hdl.handle.net/10261/221756 | DOI: | 10.1039/JA9951000859 | Identificadores: | doi: 10.1039/JA9951000859 issn:: 0267-9477 |
