“…Already in the early 1990s, LA-ICP-MS has been successfully used for steel analysis. 85 Only a couple of further reported works can be found in literature. Compared to investigations with nanosecond laser instrumentation, 86 Wiltsche and Günther performed LA-ICP-MS experiments with femtosecond lasers, coming to the conclusion that calibration even without matrix-matched standards is feasible.…”

“…Rapid, multi-elemental analysis from trace concentration levels (less than parts per million) up to the percent range have been performed in various applications [11]. Several publications describe the use of Q-switched Nd:YAG lasers for the analysis of minor and trace elements in metallurgical samples [14,15]. These laser systems have pulse durations of a few nanoseconds.…”

Femtosecond laser ablation inductively coupled plasma mass spectrometry was used for the quantification of 23 metallurgical relevant elements in unalloyed, alloyed and highly alloyed steels, and super alloys. It was shown that by using scanning mode ablation with large ablation spot diameters (250 μm), stable and representative sampling can be achieved for the majority of elements, except for bismuth and lead. For Bi and Pb up to 46%, temporal relative standard deviation (TRSD) was encountered, whereas for most other elements, the TRSDs were below 10%. Calibration with matrix-matched and non-matrix-matched standards provided similar agreement within the uncertainty of the certified values. However, the non-matrix-matched standard-based quantification was more influenced by interferences rather than ablation- or excitation-related matrix effects. The method was validated using 34 certified reference materials. (52)Cr, (51)V, or (55)Mn were used as internal standards due to the fact that the Fe concentration was not certified for the majority of reference materials. The determined concentrations for major and minor elements indicate that the total matrix internal standardization (100 wt.%) is applicable, which requires no knowledge about the steel samples prior to analysis.

“…It has been successfully applied to the direct analysis of steel composition and to the depth profile of different coatings on steel substrate. Yasuhara et al [7] studied the optimum conditions for fixed Q pulse mode and Q-switched pulse mode, demonstrating that the Q-switched pulse mode was better for both non-metallic elements and elements with a high boiling-point. When determining non-metallic elements (Si, P), in order to correct changes in background intensity, normalization with the Fe matrix and with the Ar ion is proposed.…”

A methodology for bulk analysis of Al and Ti and for determination of soluble and total Al and Ti concentration in steel samples by laser ablation inductively coupled plasma mass spectrometry was developed. The spatial distribution (both at surface and within the sample) of the insoluble fraction of Al and Ti was also qualitatively estimated. Certified reference materials (CRMs) SS-451 to 460 (carbon steel) and 064-1 (Nb/Ti interstitial free steel), from BAS, and JK 2D (carbon steel) and JK 37 (highly alloyed steel), from SIMR, were studied. It was demonstrated that the insoluble fraction of Al and Ti is heterogeneously distributed. A series of nine glass samples (fused beads) with fixed Fe content and different Al and Ti contents was prepared by melting appropriate amounts of Fe(2)O(3), Al(2)O(3) and TiO(2) with a lithium tetraborate-sodium carbonate mixture. Quantitative determinations were performed by using calibration graphs obtained from the synthetic fused beads, with (57)Fe as internal standard; line scan laser sampling mode was used, focusing the laser beam at the sample surface. The optimized laser operating parameters were: laser pulse energy of 1.5mJ, pulse repetition rate of 5Hz, scanning speed of 5microm s(-1) and preablation time of 20s. The concentrations obtained for bulk analysis of CRM samples corresponded with the certified values within the experimental uncertainty. An acceptable concordance between certified and found values was attained for the determination of soluble and total Al and Ti in CRM 064-1 sample.
