“…Depending on the laser wavelength, beam divergence, beam mode quality, and focusing optics, lateral resolution on the order of 10 m can be obtained (73). LIBS has been used for compositional mapping, i.e., spatial mapping of the elemental composition of a sample, for a number of applications including: image mapping a copper conductor pattern from a printed circuit board (79), field analysis of inorganic wood preservatives (80), generating distribution maps of poisoning elements (phosphorous [P], Zn, and Pb) in automobile catalytic converters (81), large area mapping of non-metallic inclusions in stainless steel (82), scanning microanalysis of aluminum alloys (83), and surface mapping of granite samples (84).…”

“…The imaging capability of Laser-induced breakdown spectroscopy (LIBS) represents an attractive way of development for the technique, with innumerable applications in various fields, such as geology [1][2][3], industry [4][5][6][7][8], surface science [9,10] and biology [11][12][13][14][15]. In LIBS imaging, laser-induced plasma are generated continuously while scanning the sample surface over the region of interest.…”

Nowadays, the use of catalysis is implied in almost all industrial process. Their use allows improving productivity, synthesis yields and waste treatment as well as decreasing the energy costs. The increasingly stringent requirements in terms of reaction selectivity and environmental standards impose an ever more accurate knowledge and control of their operations. However, the characterization techniques struggle to develop and often require equipment with high complexity.In this paper, we demonstrate a novel elemental approach with an all-optical design allowing quantitative space-resolved analysis to be performed with ppm-scale limit of quantification and µm-scale resolution. This approach, based on laser-induced breakdown spectroscopy (LIBS), is distinguished by its simplicity of use, all-optical design, and speed of operation. This work was conducted on palladium-based porous alumina catalyst, used for the selective hydrogenation process in the field of petrochemistry. We report an exhaustive study on the quantification capability of this technique with the possibility to perform imaging measurement over a large dynamical range, typically from few ppm to %. These results offer new insight into the use of LIBS imaging in the industry and paves the way for innumerable applications.2

“…Laser microanalysis should be relevant to any spot diameter below the bulk homogeneity of the sample. Taking into account the homogeneity scale of most materials and competitive techniques, a lateral resolution below 10 µm is required [6][7][8][9][10]. This technique may be called microLIBS, although LIBS microprobe would be more appropriate.…”
