Successful Pu disposition by immobilization in glass or ceramic form requires accurate and precise knowledge of impurity amounts. Analysis of Pu material by conventional liquid nebulization requires dissolution, which is difficult due to a refractory nature of the samples. Laser ablation is a suitable sampling technique for direct analysis of solids. This paper demonstrates the procedures that were established for PuO 2 analysis using laser ablation ICP-MS. Pressed pellets prepared from CeO 2 were used to simulate PuO 2 .Effects of laser conditions, sample preparation, and matrix composition, specifically mass of a matrix element and color, on the analyses of CeO 2 , Bi 2 O 3 , and PtO 2 based pressed pellets was examined. Influence of mixing/grinding time on particle sizes, sample homogeneity, and ablation efficiency was investigated. Laser conditions that produce stoichiometric sampling were examined.

Laser ablation (LA) is a unique technique to transform a solid sample into vapor‐phase constituents, which then can be chemically analyzed by atomic spectroscopy. Ablation brings many exciting capabilities to the field of chemical analysis, primarily because of the laser‐beam properties. The ability to analyze directly any solid samplewithout sample preparation and minimal sample‐quantity requirements are just some of the unique capabilities. This article discusses current issues related to using LA in atomic spectroscopy. A general introduction to LA sampling is presented along with a comparison with other solid sampling techniques. The critical issues for all analytical techniques are calibration, accuracy, and sensitivity. Techniques that have been demonstrated to address these analytical characteristics and define these parameters for LA are investigated in detail. Finally, many unique applications are described, ranging from dating geological materials to providing crime‐scene evidence. Most of these applications could not be performed without the use of a laser beam. The inductively coupled plasma (ICP) will be emphasized in this article because it is currently the most prevalent excitation and ionization source for chemical analysis using LA.

Commercial low-cost laser induced breakdown spectroscopy (LIBS) has been successfully employed for the quantitative analysis of a Cu-based alloy using a Nd:YAG laser at 1064 nm. The main aim of the present investigation is to explore the benefits of a commercial low-cost LIBS setup. It was recognized that some trace elements such as Al and S could not be detected by LIBS even with a high-resolution spectrometer. The main difficulties in quantifying Cu as a basic component of a brass alloy are related to the self-absorption of Cu spectral lines, with the effect complicated at Cu concentrations higher than 65%. However, few Cu lines such as that at 330.795 nm would be helpful to use due to their lower susceptibility to self-absorption. LIBS, flame atomic absorption spectrometry (FAAS), and wavelength dispersive X-ray fluorescence (WDXRF) were compared for the detection of major and trace metals in the Cu-based alloy. In the case of WDXRF, the brass samples were identified by using a standardless quantitative analysis program depending on a fundamental parameter approach. The quantitative analysis results were acceptable for most of the major and minor elements of the brass sample. Therefore, commercial low cost LIBS would be useful for quantitative analysis of most elements in different types of alloys.Keywords: brass alloy, laser-induced breakdown spectroscopy, wavelength dispersive X-ray fluorescence, atomic absorption spectrometry.Introduction. Laser-induced breakdown spectroscopy (LIBS) is a powerful and fast technique for a lot of applications in environmental monitoring, engineering, material identification, and thin film deposition [1-3]. It has grown as an analytical technique for rapid analysis of a large variety of materials present in solids, gases, and liquids [4][5][6]. This technique provides the advantages of multi-element detection, suitability to remote measurement, and minimal sample preparation. Nevertheless, it suffers from emission signal fluctuation, self absorption, and matrix effects [7,8], which may restrict the LIBS sensitivity to some extent. It was reported that the matrix composition in analyzed materials has a substantial impact on the accuracy of the elemental analysis [7,8]. The improvement of the signal quality and correction of the self-absorption and matrix effects are still hot topics in LIBS applications. The signal fluctuation problem in the LIBS analysis is caused by experimental features such as the laser pulse fluctuation, heterogeneity of the samples, instability of the plasma position, and inverse bremsstrahlung radiation. Averaging the spectral signals over a number of laser shots is essential in order to decrease the influence of this problem. For different experimental LIBS setups, a good understanding of fundamental processes is essential in order to obtain reliable results. The LIBS analytical peculiarities and the deep knowledge developed on laser-induced plasma characteristics clearly suggest the benefits from LIBS methodology for reasonable analysis requirements.L...
