Comparative study of different methodologies for quantitative rock analysis by Laser-Induced Breakdown Spectroscopy in a simulated Martian atmosphere

Nanofilm-enhanced femtosecond laser-induced breakdown spectroscopy

“…LIBS technique offers a number of advantages, such as real time analysis, remote sensing, simple experimental setup and so on. Thanks to these advantages, LIBS is applied in many fields, such as soil testing, 1 nuclear waste storage, 2 space exploration, 3 biology science. 4 However, compared with other well-established atomic spectral analysis techniques, conventional LIBS performs not well in sensitivity and precision.…”

Correction of self-absorption effect in calibration-free laser-induced breakdown spectroscopy by an internal reference method

“…Compared with other atomic emission spectral analysis techniques, the LIBS has many benefits, such as the capability of multi-element simultaneous analysis, applicability to all sample types like solids, liquids, and gases, less sample requirement, lack of sample preparation, and quickness of data acquisition. During the last two decades, the applications of LIBS have increased considerably, including industrial production control and quality assurance [3][4][5], environmental protection [1,[6][7][8], explorations of outer space [9], cultural heritage conservation [10], and medicinal studies [11].…”

“…This method requires that the measurement conditions of the reference samples match with the measurement conditions of the objects analyzed. Moreover, sometimes making the reference samples that have the absolutely same matrices as the samples analyzed is difficult or even impossible [9]. Consequently, the approach of calibration curves is appropriate to laboratorial analysis and not compatible with field analysis for variable circumstances or priori unknown samples.…”

Automatic estimation of varying continuum background emission in laser-induced breakdown spectroscopy

“…Laser-induced breakdown spectroscopy is a powerful analytical technique with a wide range of applications for fundamental purposes and material analysis [1][2][3][4][5][6][7]. In LIBS, plasma is generated by focusing a laser beam with high power onto a sample surface, and the emission from the plasma is collected with optics for the analysis of the elemental composition of the sample.…”
