“…The use of a compact detector was also reported, without details about the temporal settings of acquisition [36]. In Sun and Yu [18], the limitation due to the fixed integration gate width (1 ms) of an Ocean Optics spectrometer was overcome by calculating the difference of two spectra collected at different delay values.…”

“…Most frequently, the CF-LIBS analysis has been applied to solid materials: aluminum alloys [7,[15][16][17][18][19], steel and iron alloys [15,[18][19][20], precious alloys for jewelry [21,22], copper alloys [19,[23][24][25][26][27][28], archaeological copper artifacts [24,29], glasses [23], pigments on roman frescoes [30] and on parchments [31], soils and rocks [32][33][34], meteorites [35], coral skeletons [36], human hair [37].…”

“…The main assumptions of CF-LIBS are that the following conditions are satisfied; local thermal equilibrium (LTE), absence of self-absorption and the stoichiometric ablation. The electron densities for the experiments carried out in this work are in the order of several 10 16 (cm −3 ), two orders of magnitude higher than the lowest limit of the electron densities, satisfying the McWhirter criterion [27][28][29][30]. It has been recently reported that the McWhirter criterion alone is not sufficient to conclude that LTE conditions are satisfied [19,31], and that additional measurements are necessary.…”

a b s t r a c t Keywords:Laser-induced breakdown spectroscopy (LIBS) Calibration-free LIBS Liquid-phase laser ablation Quantitative analysis Long-pulse laser Long-ns-duration, single pulse laser-induced breakdown spectroscopy (LIBS) is known to be an effective method to observe well resolved spectra from samples immersed in water at high hydrostatic pressures. The aim of this study is to investigate whether the signals obtained using this method are suitable for quantitative analysis of chemical composition. Six certified brass alloys consisting of copper (Cu), zinc (Zn) and lead (Pb) were measured underwater using a laser pulse of duration 250 ns, and their compositions were determined using calibration-free LIBS (CF-LIBS) and corrected CF-LIBS (CCF-LIBS) methods. The mass fractions of Cu and Zn calculated using CF-LIBS showed better agreement with the certified values than those determined using CCF-LIBS, with relative errors of Cu 4.2 ± 3.3 % and Zn 7.2 ± 6.4 %. From the results, it can be said that the difference of preferential evaporation and ablation among elements does not need to be considered for underwater measurements with the long-pulse LIBS setup used in this work. While the results indicate that the CF-LIBS method can be applied for in situ quantitative analysis of major elements with concentrations N~10 %, the mass fractions determined for Pb, with concentrations b 5 % had large relative errors, suggesting that an alternative method is required to quantify minor elements.

“…Singh et al 34 also utilized this method for the quantitative analysis of different kinds of salt samples and suggested that Saindha salt, commonly known as rock salt, may be beneficial for patients suffering from chronic kidney disease. Pandhija et al 111 used CF-LIBS for the quantitative measurement of the concentrations of elements including Ca, Sr, Mg, C, O, Na, K and Fe in coral samples which contains organic constituents identical to those of the human skeleton.…”

Applications of laser-induced breakdown spectroscopy (LIBS) are growing rapidly and continue to extend its horizon to include a broad variety of materials. The recent progress made in the field has transformed LIBS from being an elemental analysis technique to the one applicable for the analysis of molecularly complex biological samples and specimens. LIBS has thus, proven its capability as detection, characterization and identification tool for studying a range of biological specimens and biomaterials. A review is presented here to discuss recent developments and future potential of LIBS and its viability for possible biomedical applications.
