| Description | Laser-Induced breakdown spectroscopy (LIBS) a relatively young technique of atomic emission spectroscopy, uses as its excitation source a focused laser pulse and this effective combination brings to the field of elemental analysis a number of significant advantages. Although the first LIBS analysis happened shortly after the construction of the first laser in 1962, development at a much larger scale occurred at the beginning of the 1980s mainly due to the production of modern powerful Nd:YAG lasers and charge coupled device (CCD) detectors. Today, LIBS is the subject of ever increasing interest due to its speed, relatively simple instrumentation setup, no demands for a sample preparation and the possibility to determine most of the periodic table elements, along with other attributes. LIBS can be used to perform a spatial resolved analysis, thus is capable of being used for depth profiling and surface mapping. Surface mapping and creating so-called “chemical maps” (or “chemical images” of the analysed sample) are presented here as an example of LIBS applications. |
