“…One of the better known attempts in this category is the method developed by Gornushkin et al [123], which incorporates the plasma temperature and number densities for selected species as input variables and uses a Monte Carlo approach for the minimization of multivariate functions (MC-LIBS). Its accuracy was found to be somewhat poorer than that of CF-LIBS [124].…”

Laser-induced breakdown spectroscopy (LIBS) has become an established analytical atomic spectrometry technique and is valued for its very compelling set of advantageous analytical and technical characteristics. It is a rapid, versatile, non-contact technique, which is capable of providing qualitative and quantitative analytical information for practically any sample, in a virtually non-destructive way, without any substantial sample preparation. The instrumentation is simple, robust, compact, and even enables remote analysis. This review attempts to give a critical overview of the diverse progress of the field, focusing on the results of the last five years. The advancement of LIBS instrumentation and data evaluation is discussed in detail and selected results of some prominent applications are also described.

“…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 CF-LIBS approach was tested in the analysis of space resolved spectra in the paper by Herrera et al [17], which regarded an aluminum alloy sample irradiated in a reduced atmospheric pressure of 0.1 mbar. Plasma emission was recorded with an imaging spectrometer coupled to a CCD and the resulting image was sectioned in 11 regions along the plasma propagation axis, z.…”

“…While matrix-matched calibration-curves can be used for quantitative analysis of solids (Hunter and Piper, 2006;Eppler et al, 1996), various groups have successfully implemented CF-LIBS to quantify the composition of metal alloys (Tognoni et al, 2007(Tognoni et al, , 2010Ciucci et al, 1999;Herrera et al, 2009a) and metal oxides (Praher et al, 2010) in a gaseous environment, achieving relative accuracies of 5 to 15% for major elements. With regard to interpretation of natural sediments and rocks, most studies report degradation in accuracy due to the complexity of the signals obtained (Tognoni et al, 2010;Herrera et al, 2009b;Colao et al, 2004;De Giacomo et al, 2007).…”

a b s t r a c tSpectroscopy is emerging as a technique that can expand the envelope of modern oceanographic sensors. The selectivity of spectroscopic techniques enables a single instrument to measure multiple components of the marine environment and can form the basis for versatile tools to perform in situ geochemical analysis. We have developed a deep-sea laser-induced breakdown spectrometer (ChemiCam) and successfully deployed the instrument from a remotely operated vehicle (ROV) to perform in situ multi-element analysis of both seawater and mineral deposits at depths of over 1000 m. The instrument consists of a long-nanosecond duration pulse-laser, a spectrometer and a high-speed camera. Power supply, instrument control and signal telemetry are provided through a ROV tether. The instrument has two modes of operation. In the first mode, the laser is focused directly into seawater and spectroscopic measurements of seawater composition are performed. In the second mode, a fiberoptic cable assembly is used to make spectroscopic measurements of mineral deposits. In this mode the laser is fired through a 4 m long fiber-optic cable and is focused onto the target's surface using an optical head and a linear stage that can be held by a ROV manipulator. In this paper, we describe the instrument and the methods developed to process its measurements. Exemplary measurements of both seawater and mineral deposits made during deployments of the device at an active hydrothermal vent field in the Okinawa trough are presented. Through integration with platforms such as underwater vehicles, drilling systems and subsea observatories, it is hoped that this technology can contribute to more efficient scientific surveys of the deep-sea environment.
