LIBS<\/a> (L<\/strong>aser-I<\/strong>nduced B<\/strong>reakdown S<\/strong>pectroscopy) is a technique for elemental analysis. A short, focused laser pulse generates a plasma on the sample. Its light is analysed using a spectrometer, providing information about the elements present.<\/p>\n\n\n\n

The technique enables the rapid analysis of different materials \u2013 from identifying individual elements to determining their concentrations. Spatially resolved analysis and depth profiling are also possible.<\/p>\n<\/div>\n\n\n\n

How does LIBS work?<\/h2>\n\n\n\n

A short, high-energy laser pulse is focused onto the sample. This ablates a small amount of material and generates a plasma. The plasma emits light with characteristic spectral lines, which is collected by a spectrometer. These lines allow the elements present to be identified; with suitable calibration, their concentrations can also be determined.<\/p>\n\n\n\n
