“…A recent contribution describes a limit of detection of 10.5 mg L À1 in water, while this value decreases to 18.4 mg L À1 after enrichment in filter paper. 21 The present work describes the effects of pressure, flow rate, and laser pulse repetition rate on the emission signal of lithium in order to optimize the experimental conditions for obtaining higher sensitivity, demonstrating the usefulness of LIBS for oceanographic studies.…”

This paper describes the effects of laser pulse rate and solution flow rate on the determination of lithium at high pressure for water and 2.5% sodium chloride solutions using laser-induced breakdown spectroscopy (LIBS). Preliminary studies were performed with 0–40 mg L−1 Li solutions, at ambient pressure and at 210 bar, and in static and flowing (6 mL · min−1) regimes, for a combination of four different measurement conditions. The sensitivity of calibration curves depended on the pressure and the flow rate, as well as the laser pulse rate. The sensitivity of the calibration curve increased about 10% and 18% when the pressure was changed from 1 to 210 bar for static and flowing conditions, respectively. However, an effect of flow rate at high pressure for both 2 and 10 Hz laser pulse rates was observed. At ambient pressure, the effect of flow rate was negligible, as the sensitivity of the calibration curve decreased around 2%, while at high pressure the sensitivity increased around 4% when measurements were performed in a flow regime. Therefore, it seems there is a synergistic effect between pressure and flow rate, as the sensitivity increases significantly when both changes are considered. When the pulse rate is changed from 2 to 10 Hz, the sensitivity increases 26–31%, depending on the pressure and flow conditions. For lithium detection limit studies, performed with a laser pulse energy of 2.5 mJ, repetition rate of 10 Hz, gate delay of 500 ns, gate width of 1000 ns, and 1000 accumulations, a value around 40 µg L−1 was achieved for Li solutions in pure water for all four measurement conditions, while a detection limit of about 92 µg L−1 was determined for Li in 2.5% sodium chloride solutions, when high pressure and flowing conditions were employed. The results obtained in the present work demonstrate that LIBS is a powerful tool for the determination of Li in deep ocean conditions such as those found around hydrothermal vent systems.

“…Cortez & Pasquini 32 used lter paper combined with the ring-oven technique for the simultaneous determination of Na, Fe and Cu in fuel by LIBS, obtaining limits of detection (LOD) ranging from 0.3 to 0.7 mg L −1 . He et al 13 used a small piece of paper measuring 3.0 cm 2 for Li determination, achieving a LOD of 0.0184 mg L −1 , a value signicantly lower than the 10.5 mg L −1 obtained also by LIBS with direct measurement in liquids. Furthermore, increased sensitivity and correction of matrix effects can be achieved using internal standards, such as C or CN emission from the cellulosic substrate.…”

“…Laser-Induced Breakdown Spectroscopy (LIBS), typically employed in solid sample analysis, has proved to be also efficient for liquid analysis. 12–15 Compared to the conventional elemental analysis techniques such as Inductively Coupled Plasma Atomic Emission Spectrometry (ICP OES) 16,17 and Atomic Absorption Spectrometry (AAS), 18 LIBS offers several advantages that include minimal or no sample preparation, quick and simple measurements and multielement analysis. 19 Due to the high portability potential of the LIBS instrumentation, it could be implemented on oil platforms, generating a faster and in loco response to the scaling potential of produced waters.…”

“…The optical emission from the laser-induced plasma can be collected with a spectrometer for the further elemental or chemical analysis. Thus, LIBS also offers the compelling advantages of fast detection speed, high spatial resolved sensitivity up to trace levels in any type of sample matrix 2,3,[5][6][7] , as well as broad element coverage from light to heavy element detection. So far, much work has focused on the LIBS for elemental and quantitative analysis in the wavelength range from VUV 8 to UV-VIS 5,7,9,10 .…”

Laser-induced breakdown spectroscopy (LIBS) is an elemental analysis method thanks to minor sample preparation, rapid analysis, and a spatially resolved sensitivity down to trace level in any kind of sample matrix. State-of-the-art LIBS is operated in the optical spectral range (UV-Vis). Unfortunately, the application of LIBS in material detection is limited by the low precision and repeatability. This is particularly critical for inhomogeneous materials and alternative methods are desirable. Light elements such as Li, as well as F, are difficult to be characterized. The dual LIBS performance was initially studied in a simpler matrix such as LiF, radially collecting simultaneously the XUV and OES spectra from the same laser shot. For the case of LiF, XUV signals proved significantly more stable than in the case of LIBS-OES. The signal of F can be also seen clearly in the spectrum. Observation of the plasma emission at even shorter wavelengths in the extreme ultraviolet (wavelength range 5-20 nm) is supposed to improve the state-of-art limitations of LIBS.
