Laser-induced breakdown spectroscopy (LIBS) is a rapidly developing technique for chemical materials analysis. LIBS is applied for fundamental investigations, e.g., the laser plasma matter interaction, for element, molecule, and isotope analysis, and for various technical applications, e.g., minimal destructive materials inspection, the monitoring of production processes, and remote analysis of materials in hostile environment. In this review, we focus on the element analysis of industrial materials and the in-line chemical sensing in industrial production. After a brief introduction we discuss the optical emission of chemical elements in laser-induced plasma and the capability of LIBS for multi-element detection. An overview of the various classes of industrial materials analyzed by LIBS is given. This includes so-called Technology materials that are essential for the functionality of modern high-tech devices (smartphones, computers, cars, etc.). The LIBS technique enables unique applications for rapid element analysis under harsh conditions where other techniques are not available. We present several examples of LIBS-based sensors that are applied in-line and at-line of industrial production processes.

Laser Induced Breakdown

With the rapid development of spectroscopy technology, laser induced breakdown spectroscopy (LIBS) has become the focus of elemental analysis technology in recent years. With its advantages of non-destructive testing, rapid and multi-element detection, LIBS has been successfully applied to the analysis of geochemical characteristics of soil elements in river basins. The application of LIBS technology in soil elemental analysis of watershed is reviewed in detail. The accuracy of LIBS technology in soil element analysis is studied with the Masha River Basin as the research area. On this basis, the key problems in the process of soil element analysis, such as spectral enhancement methods and quantitative analysis methods, were analyzed. The analysis results show that the accuracy of elemental analysis between LIBS and traditional chemical methods is not much different, but the analysis time of LIBS method is shorter. Methods such as MLR, PLSR, and internal standard methods can improve the fit of the calibration curve and reduce the quantitative analysis error. By changing parameters such as laser energy and delay time, the spectral intensity can be enhanced to reduce the effects of matrix effects. In the process of elemental analysis, the effects of soil physical and chemical parameters should be considered comprehensively, and appropriate quantitative analysis methods should be adopted to improve the accuracy of the analysis results.

Laser Induced Breakdown

In this research, we investigate the minor chemical elements contained in the diesel particulate matter (DPM) exhaust emissions, generated by in-use diesel engine passenger vehicles. For this purpose, we apply a high-resolution optical emission spectroscopy technique, for precise spectrochemical analysis of diesel particulate matter. By means of laser-induced breakdown spectroscopy (LIBS) analytical method, we qualitatively and quantitatively characterise detected minor chemical elements in DPM. Particulate matter samples were obtained from in-use diesel engine passenger vehicles of diverse types and models from major brand car producers in Europe. We analysed particulate matter, extracted from the exhaust manifold part, from vehicles, which are used in daily life environment. The LIBS technique has revealed the presence of minor chemical elements in DPM -silicon, nickel, titan, potassium, strontium, and molybdenum with diverse concentrations.

Laser Induced Breakdown

Spectral investigations in the UV-VIS range of selected Al alloys and composites, used in the construction of armament components as well as drones, were performed using LIBS technique. Two Nd:YAG lasers were applied: a short pulse 4 ns 60 mJ laser and a long pulse 200/400 (up to 1000) us (~ 2/4 up to 10 J) laser. In experiments with a short laser pulse only atomic spectra were observed while for long pulses, also molecular transitions have been recorded. Electron temperatures of created plasma were found on the base of Boltzmann law. Temperatures are clearly higher for short pulse excitation. Full Text: PDF ReferencesA. Miziolek, V. Palleschi and I.
