When the output from a pulsed laser is forced onto a small spot of a sample, optically induced plasma, called laser-induced plasma (LIP) is formed at the surface. The plasma is formed when the laser power density exceeds the breakdown threshold value of the surface. The plasma can be used in sampling but is proposed as a source for atomic emission spectrometry (AES). In this case the technique is referred to as laser induced breakdown (emission) spectrometry (LIBS). The spectrally and temporally resolved detection and subsequent determination of the specific atomic emission reveals analytical information about the elemental composition of the sample, including solids, liquids and gases. This book is devoted to the analytical technique of laser-induced breakdown spectrometry. An introduction covering some basic principles of atomic emission spectrometry, analytical performance characteristics, and a comparison to more conventional techniques provides background information for the reader. The book is then conveniently divided into three parts: the first part described the instrumentation required and options available, the second part on fundamental studies of the laser plasma, and the third part on applications. Finally the future development of LIBS is presented.

The purpose of this project is to show how laser-induced breakdown spectroscopy (LIBS) and digital imaging processing can be used for indirect dating, authentication, and identification of oil paint pigments. Ten oil paint pigments from traditional and modern palettes were used for the analysis. Since synthetic paints (modern) were not available prior to the 19 century, the presence of a synthetic paint could allow for determination of whether the artwork was conserved in the past or it if was a forgery. LIBS and digital imaging processing were used to analyze the oil paint pigments in both pure form and binary mixture form. In LIBS, a laser pulse is focused on a surface and this focused pulse heats, ablates, atomizes, and ionizes the surface material. This causes the formation of a plasma and the light emitted by the plasma is collected, spectrally resolved, and detected. Elements contained in the sample can be identified by their distinctive spectral signatures. LIBS can provide both qualitative and quantitative results. It has many applications from space to defense including metal sorting, explosive and fissile material detection, lead in paint determination, heavy metal contamination in soil, identification of cultural heritage objects, etc. For this part of the study, the data was taken on pure and binary mixtures using ten shot accumulation analysis. The data was analyzed to determine what spectral emission lines could be used to uniquely determine one pigment from another. The pure and mixture pigments in single and multilayer samples were analyzed with image processing technology and algorithms. The digital images were used to create image histograms. Using the image histogram, the peak location was used to determine if differences among the pure and binary mixture pigments existed and whether unique peak locations in the histograms of the pure pigments or mixture pigments were seen.

Under high irradiation, a fourth state of matter named plasma can be obtained. Plasmas emit electromagnetic radiation that can be recorded in the form of spectra for spectroscopic elemental analysis. With the advent of lasers in the 1960s, spectroscopists realized that lasers could be used simultaneously as a source of energy and excitation to create plasmas. The use of a laser to ignite a plasma subsequently led to laser-induced breakdown spectroscopy (LIBS), an optical emission spectroscopy capable of analyzing samples in various states (solids, liquids, gases) with minimal sample preparation, rapid feedback, and endowed with in situ capability. In this dissertation, studies of LIBS for multi-elemental analysis and geological applications are reported. LIBS was applied to cosmetic powders for elemental analysis, screening and classification based on the raw material used. Principal component analysis (PCA) and internal standardization were used. The intensity ratios of Mg/Si and Fe/Si observed in talcum powder show that these two ratios could be used as indicators of the potential presence of asbestos. The feasibility of LIBS for the analysis of gasification slags was investigated and results compared with those of inductively-coupled plasma−optical emission spectrometry (ICP-OES). The limits of detection for Al, Ca, Fe, Si and V were determined. The matrix effect was studied using an internal standard and PLS-R. Apart from V, prediction results were closed to those of ICP-OES with accuracy within 10%. Elemental characterization of outcrop geological samples from the Marcellus Shale Formation was also carried out. The matrix effect was substantially reduced. The limits of detection obtained for Si, Al, Ti, Mg, Ca and C were determined. The relative errors of LIBS measurements are in the range of 1.7 to 12.6%. Gate delay and laser pulse energy, have been investigated in view of quantitative analysis of variation of trace elements in a high-pressure environment. Optimization of these parameters permits obtaining underwater plasma emission of calcium with quantitative results on the order of 30 ppm within a certain limit of increased pressure. Monitoring the variation of the trace elements can predict changes in the chemical composition in carbon sequestration reservoir.

The utilization of Laser Induced Breakdown Spectroscopy (LIBS) as a potential material characterization technique has been demonstrated through academic and industrial research in past. LIBS has been applied for lateral surface scanning of materials and in depth resolution analysis. The necessity of improving lateral and depth resolution has led to the the development of microLIBS, a regime using low energy microjoule laser pulses. Femtosecond lasers have advanced the technique by its ability to produce high finer micromachined features. The optimization of pulse energy, optics, detectors and experimental environments are required to obtain precise surface microanalysis using LIBS. This thesis has been focused on a number of essential aspects of LIBS microanalysis. Laser ablation characteristics of materials depend on laser parameters and material properties. The single shot ablation threshold of chromium has been determined using UV femtosecond laser pulses and compared with two temperature model (TTM) predictions. The spatio-temporal evolution of the femtosecond laser induced micro-plasma plumes were characterized in the nanojoule ablation regime. The plume splitting, angular distribution of the plumes, plume lengths and plume images at threshold energies were characterized. Analytical models were used to compare plasma plume expansion and propagation characteristics. A LIBS depth profiling technique has been studied together with deep blind hole drilling using femtosecond laser pulses. The material removal rates were measured and compared with analytical calculations. The depth sensitive region that contributes to the LIBS emission has been evaluated for a single shot depth profiling study. It has been demonstrated by experiment and TTM model calculations that the depth sensitive region is much smaller than the ablated crater depth. Thin chromium lines on silicon wafers were prepared and scanning microanalysis across these metal strips using UV femtosecond pulses were carried out. Lateral resolution of the order of a micron has been obtained using LIBS.

The analytical figure of merit of a laser-induced breakdown (LIBS) system was evaluated for technetium measurements in liquid. LIBS data of elements that have similar properties to Tc such as Cr, Mn, and Re were studied. Various optical geometries which produce the laser spark in and at the liquid sample were tested. The calibration curve for Mn, Cr, and Re were obtained at the optimized experimental conditions with bulk liquid and liquid jet. We found that measurements using a liquid jet provide better detection limits than the bulk liquid measurements. The detection limits of Mg, Cr, Mn, and Re in a liquid jet measurement are found to be 0.1, 0.4, 0.7, and 10 ppm, respectively.
