Laser-induced breakdown spectroscopy (LIBS) is a well-established elemental analysis method, thanks to negligible sample preparation, rapid analysis, and spatially resolved sensitivity down trace level, in any kind of matrix. State-of-the-art LIBS operated the optical spectral range (UV-VIS). Unfortunately, measurement precision limited by moderate stability repeatability plasma emission. The detection crucial elements such as light halogens are also limited. This particularly critical for inhomogeneous materials where signal fluctuation related spatial distribution. To overcome these disadvantages specific, techniques arrangement often required. XUV Spectroscopy (LIXS) has some intrinsic advantages overcoming above mentioned limitations it can support spectroscopic information collected UV-VIS range.
