“…Note that the signal intensity of 71 Ga increased with scan speed for the same repetition rate. This result is similar to that by Gonzalez et al [30] where the low signal intensity at low scan speed for a fixed repetition rate was attributed to the accumulation of particles in front of the surface, decreasing the ablation and/or transport efficiency due to the absorption/diffusion of the laser beam. The signal increase of 71 Ga for increasing repetition rate at the fixed scan speed of 300 μm/s may be due to an increased amount of ablated mass.…”

“…Based on these results, repetition rate of 200 Hz and scan speed of 500 μm/s were selected as the optimal sampling conditions in this study to achieve high ICP-MS signal and low fluctuation. At this condition, the complete ablation of a rectangular crater took about 6.65 s. The cross-sectional profile of the rectangular crater showed that the surface between craters was significantly elevated due to accumulation of ablated particles [30]. Since the thickness of CIGS layer of the sample in Fig.…”

“…1(a) are closely related to the ablation conditions. Gonzalez et al [30] reported that the ICP-MS signal intensity and crater profile differed if the scan speed and repetition rate had changed even at the same number of overlapping pulses. The primary reason for these changes in ICP-MS response is the variation in particle characteristics such as particle size and size distribution sampled during laser-material interactions.…”

This work reports that the composition of Cu(In,Ga)Se 2 (CIGS) thin solar cell films can be quantitatively predicted with high accuracy and precision by femtosecond laser ablation-inductively coupled plasma-mass spectrometry (fs-LA-ICP-MS). It is demonstrated that the results are strongly influenced by sampling conditions during fs-laser beam (λ = 1030 nm, τ = 450 fs) scanning on the CIGS surface. The fs-LA-ICP-MS signals measured at optimal sampling conditions generally provide a straight line calibration with respect to the reference concentrations measured by inductively coupled plasma optical emission spectroscopy (ICP-OES). The concentration ratios predicted by fs-LA-ICP-MS showed high accuracy, to 95-97% of the values measured with ICP-OES, for Cu, In, Ga, and Se elements.

“…In some cases, laser repetition rate was found to have a great influence on fractionation due to the fast overlapping of the laser pulses, which induces the heating of the sample, with no particular changes in the aerosol particle size distribution. 15,37 However on the other hand, fractionation was found to be independent of pulse repetition rate (from 4 Hz to 100 Hz), 38,39 suggesting that elemental fractionation for a 193 nm nanosecond laser is not a function of heating of the sample, since a higher pulse repetition rate leads to higher temperatures at the site of ablation. Therefore, the aim of this work is to investigate in detail the effect of the laser repetition rate on fractionation effects using a high repetition rate infrared femtosecond laser ICP-MS. For this purpose, elemental ratios of aerosols produced by fs-LA of silicate glass SRM NIST 610 were studied from moderate fluence values of 5 J cm À2 up to 25 J cm À2 , and laser repetition rate in the range of 0.1-10 kHz.…”

An IR-femtosecond laser ablation ICPMS coupling was used to investigate the influence of the high repetition rate on elemental fractionation effects for the analysis of silicate glass SRM NIST 610. First, elemental fractionation inherent to the ICP was minimised by working on wet plasma conditions which had greater tolerance to mass loading and demonstrated a higher robustness compared to dry plasma conditions. Because of the use of a narrow laser beam producing small craters (17 mm in diameter), a special arrangement of pulses was used to perform resulting craters of 100 mm diameter. The ablation strategy developed in this work consisted in a series of concentric circle trajectories ablated at high repetition rates by moving the laser beam rapidly thanks to a scanning beam device. Two scanner speeds (0.25 mm s À1 and 1.5 mm s À1), five laser repetition rates (from 0.1 kHz to 10 kHz) and three fluence values (5 J cm À2 , 14 J cm À2 , and 25 J cm À2) were investigated in detail. For this purpose, critical elemental ratios (namely 238 U/ 232 Th, 208 Pb/ 238 U, and 66 Zn/ 65 Cu) of aerosols produced by fs-LA of silicate glass were studied to evaluate the impact of the different laser parameters on elemental fractionation. No heating zones or preferential evaporation of elements were found depending on the repetition rate employed. However, particle-size-fractionation was measured during the ablation of the sample surface, and this effect was reduced by using a high repetition rate as well as a high scanner speed which allow the dilution of the large particles coming from the surface layer with finer particles coming to deeper levels. Additionally, the ablation rate induced by the selected ablation strategy had a low influence on fractionation effects due to the high robustness of the ICP plasma and, on the other hand, fractionation indices were not particularly affected by the laser repetition rate although they could be improved by the use of high fluence values. Finally, it could be stressed that no differences on the structure of the aerosol particles collected on membrane filters were found depending on the ablation parameters.

“…Recently, femtosecond (fs) lasers have become a promising tool in LA-ICP-MS. The NIST glasses were used for fundamental studies on the influence of the repetition rate and scan speed on the particle size distribution and LA-ICP-MS performance (Gonzalez et al 2008). Elemental fractionation in femtosecond laser ablation has been studied in detail by Garcia et al (2008a) using NIST 610 and 1412 glasses.…”

This review gives an overview of the literature on reference materials of geochemical and environmental interest for the two‐year period 2008–2009. Reference materials play an increasingly important role in all fields of geoanalytical research. This is demonstrated by the large number of publications containing data on reference materials. Although many reference materials exist, there is still a great need for certified samples, so‐called delta zero materials for stable isotopic work and homogeneous microanalytical reference materials. This review focuses on six topics: developments of certification processes of reference materials mainly postulated in ISO guidelines and the IAG protocol, new developments of the GeoReM database, investigations of powdered rock reference materials, Chinese reference materials published in Chinese journals, microanalytical reference materials and isotopic reference materials.
