LIBS is based on the technique in which plasma by the interaction of high power laser pulse with solid, liquids and gases. The laser-induced plasma is a micro- source of light, emitted by excited atomic and ionic species, which is collected by the spectrometer equipped with CCD/ ICCD. The atomic transitions and molecular bands are used for plasma diagnostic and for the quantitative and qualitative analysis of trace elements in closed contact as well at a standoff distance.
