Summary: Human biomarkers such as hair and nails provide a continuous record of element concentration indicating nutritional status and metabolic changes. CF-LIBS assisted with the standard reference line method can be used to quantify the content ratio of elements in hair and nails, with relative errors less than 10% compared to ICPOES. This method shows promise as a tool for biomedicine.

Summary: In this study, the combination of the calibration-free (CF) methodology and femtosecond laser-ablation spark-induced breakdown spectroscopy (fs LA-SIBS) was utilized for quantitative analysis of elements in aluminum alloy. The experimental setup included a femtosecond laser as the ablation source, a spark discharge to enhance plasma emission, and a compact fiber spectrometer coupled to a charge-coupled device for spectral acquisition. The CF fs LA-SIBS technique demonstrated the capability to detect and quantify major, minor, and trace elements in multi-composition alloys, with an analysis error of less than 0.3% for aluminum.

Summary: This study demonstrates the use of calibration-free LIBS for rapid and reliable quantitative spectrochemical characterizations of layered Li metal oxide cathodes containing Mo and Cr dopants. The results show that the elemental compositions estimated by LIBS are in good agreement with nominal stoichiometric values. These ex situ LIBS characterizations pave the way for future high-efficiency application of calibration-free quantitative LIBS for rapid in situ analyses of elemental composition changes in battery electrode materials under operation.

Summary: In this study, a statistical LOD definition is proposed for calibration-free LIBS based on emitter density, plasma parameters, and measurement uncertainties. The LOD is determined through the propagation of uncertainties applied to CF-LIBS calculations and is shown to depend on plasma temperature and emission line properties. The proposed expression provides a sound and thorough LOD definition for LIBS quantitative analyses, and it was validated using carbon and calcium analysis in sodium chloride samples.

Summary: The study investigates the application of the Monte Carlo algorithm in calibration-free LIBS, using a simulated spectrum similar to a metallurgical slag sample. By iterating plasma parameters until the cost function reaches its minimum, the algorithm accurately reads the concentrations of species. The algorithm is parallelized on a GPU to reduce computation time and exhibits high accuracy.

Summary: This paper discusses the use of conventional LIBS and LIBS-LIF techniques for measuring trace amounts of palladium in solid ore samples. The study optimized the performances of LIBS-LIF for spectrochemical analysis of palladium by studying the combination of excitation/fluorescence of Pd lines and plasma creation conditions. Calibration curves were established using reference materials doped with a palladium solution. The results demonstrated that LIBS-LIF could rapidly measure sub-ppm levels of palladium in solid ore samples without any sample preparation, and it could resolve the spectral interference which is problematic with conventional LIBS.

Summary: This study quantitatively analyzed trace contaminants on optical glass surfaces induced by manufacturing using LIBS. The contaminants were found to originate from the polishing process, and depth-resolved measurements were conducted by recording successive laser pulses on the same sites. The sensitivity-improved calibration-free LIBS approach demonstrated here can be applied to quantify surface contaminations in various technological applications.

Summary: Direct elemental analysis of materials using calibration-free laser-induced breakdown spectroscopy has attracted significant interest since 1999. However, the multitude of different approaches and their validation in various experimental conditions make it challenging to assess the achievable performance of this innovative analytical technique. This paper critically reviews the development of calibration-free LIBS, highlights the progress made so far, and estimates its analytical performance. Solutions are proposed to enhance accuracy by addressing sources of measurement uncertainty, thereby bringing calibration-free LIBS to the level of fully recognized analytical methods.
