“…The LIBS measurements were performed using the custom LIBS system presented in Figure and described in detail in previous reports. − In brief, the samples were placed in a chamber, which enabled the atmosphere control by introducing gas and the connection to a rotary pump. A moisture trap (GL Sciences Inc., Tokyo, Japan) was attached to the gas line between the chamber and the gas cylinder to remove the water molecules from the introduced helium or argon gas, unlike in the previous LIBS system.…”

An analytical approach that can rapidly determine a wide range of hydrogen concentration in solid-state materials has been recently demanded to contribute to the hydrogen economy. This study presents a method for estimating hydrogen concentrations ranging from 0.2 to 7.6 mass % via laser-induced breakdown spectroscopy (LIBS) in a few seconds, with an improvement in the upper limit of determination (7.6 mass %) by approximately 1.3 times compared with a previous work (5.7 mass %). This extension of the determinable concentration range was achieved by measuring the emission intensity at 656.28 nm from the sample in a helium atmosphere at 3000 Pa under focused laser irradiation and by reducing the water residues in both the sample and gas line of the LIBS system. The as-determined hydrogen concentrations in magnesium hydride (MgH 2 ) samples agreed well with those estimated through inert gas fusion/gas chromatography. The calibration curve for LIBS analysis was acquired by measuring the emission intensity at 656.28 nm of standard Mg/MgH 2 mixtures containing various hydrogen concentrations (0, 0.1, 0.2, 0.5, 1.0, 2.0, 3.0, 4.0, 5.0, and 7.6 mass %). Results indicated that the proposed LIBS-based method is applicable to the rapid quantitative analysis of hydrogen in hydrogencontaining material of MgH 2 .

“…48 Using laser-induced breakdown spectroscopy, lithium mapping of the LiCoO 2 cathode has confirmed the existence of diffuse regions. 49 Moreover, microstructural evaluations 50,51 have established one-dimensional (de)intercalation, which has been a vital assumption of the model 22 that has been settled due to the one-dimensional electric field direction in the cell.…”

“…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.
