“…The simultaneous analysing mode of the ICP-TOF-MS leads to several advantages including (i) no limitation on the number of analysed isotopes and (ii) its analysis time when compared to other ICP-MS techniques. While the ICP-TOF-MS system needs 1.5 minutes per sample to analyse the mass range from 7 Li to 238 U (6-fold analysis, 175000 sweeps), the ICP-Q-MS needs 7 minutes for 40 isotopes …”

Inductively coupled plasma mass spectrometry (ICP-MS) is a suitable tool for multi-element analysis at low concentration levels. Rare earth element (REE) determinations in standard reference materials and small volumes of molten ice core samples from Antarctica have been performed with an ICP-Time of Flight-MS (ICP-TOF-MS) system. Recovery rates for REE in e.g. SPS-SW1 amounted to ~103%, and the relative standard deviations were 3.4% for replicate analysis at REE concentrations in the lower ng L -1 range. Analyses of REE concentrations in Antarctic ice core samples showed that the ICP-TOF-MS technique meets the demands of restricted sample mass. The data obtained are in good agreement with ICPQuadrupole-MS (ICP-Q-MS) and ICP-Sector Field-MS (ICP-SF-MS) results. The ICP-TOF-MS system determines accurately and precisely REE concentrations exceeding 5 ng L -1 while between 0.5 and 5 ng L -1 accuracy and precision are element dependent.

“…Consequently, using Al/Fe and Ti/Fe ratio signals (providing that the Fe signals are those which would correspond to a 100% of this element), the values from beads and from steel samples, with similar Al or Ti content, should be comparables. Then, the calibration graphs, for Al and Ti determination in steel samples, can be constructed by normalizing the 27 Al and 48 Ti signals of the glass samples to the signal that would correspond to a 100% of Fe. The obtained plots, from the beads samples listed in Table 3, are depicted in Fig.…”

“…Aeschliman et al [26] used analyte signals from desolvated particles for a two-point calibration method, measuring online the transport of sample particulates from the ablation cell with a piezoelectric microbalance to provide signal normalization. Hoffmann et al [27] pointed out that the precision and accuracy of the results are influenced by signal standardization, calibration standards and the mass-spectrometric measuring mode. Sanborn and Telmer [28] showed that line scan mode provided some advantages over spot analysis, obviating some complications such as changes in ablation yield and element fractionation that occur with increasing pit depth and Gaussian pit morphology.…”

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.

“…By this way the velocity spread of ions will be reduced, both along and perpendicular to the flight tube, which results in small lines, better resolution and lower background. Based on this improvement an ICP-TOF-MS instrument has been developed and built up in our laboratory and used in the present study [10].…”

The aim of this extensive aerosol measurement campaign was to obtain a database for model-calculations of arctic aerosol, which play an important role in the global climate change. The ASTAR project was centered on two aircraft measurement campaigns, scheduled from 2004 to 2005, addressing both aerosol and cloud measurements, combined with ground-based and satellite observations. In the present paper one example for the analysis of ground-based aerosol particles is described. The sampling of aerosol particles was performed in a well-known manner by impaction of the particles on cleaned graphite targets. By means of a cascade impactor eight size classes between 0.35 and 16.6 Am aerodynamic diameters were separated. To analyze the metal content in the aerosol particles the targets were rapidly heated up to 2700 -C in an inductively heated vaporizer system (IHVS). An argon flow transports the vaporized sample material into the inductively coupled plasma (ICP) used as ionization source for the time of flight-mass spectrometer (TOF-MS). The simultaneous extraction of the ions from the plasma, as realized in the TOF instrument, allows to obtain the full mass spectrum of the sample during the vaporization pulse without any limitation in the number of elements detected. With optimized experimental parameters the element content in arctic aerosol particles was determined in a mass range between 7 Li and 209 Bi. Comparing the size distribution of the elemental content of the aerosol particles, two different meteorological situations were verified. For calibration acidified reference solutions were placed on the cleaned target inside the IHVS. The limits of detection (LOD) for the element mass on the target range between 2 and 200 pg for the elements studied, except Na, Mg, and Cr, which are influenced by high background. D
