Laser-induced breakdown spectroscopy (LIBS) is now a well-established, powerful, and versatile method of plasma emission spectroscopy analysis. It has been around since the 1960s but started to really bloom in the past two to three decades. Over the years, it has been successfully adapted to a great number of applications. Its analytical performance got a boost from several innovative physical approaches and now it offers a range of capabilities that is almost unparalleled in analytical science. It is capable of analyzing solid, liquid, and gaseous samples, even in a stand-off configuration, with trace or even ultra-trace sensitivity, providing not only quantitative but also highly characteristic qualitative information about the samples with microscopic spatial resolution. On top of all this, it is virtually non-destructive (micro-destructive) and local analyses are also very quick: they do not take longer than a fraction of a second. This chapter gives a comprehensive overview of the various advancements that the LIBS method has undergone in recent years and describes current practices, best approaches, and the latest analytical figures of merit.
