LIBS, or Laser Induced Breakdown Spectroscopy, is a well-established technique for the classification
(identification), and, under appropriate circumstances, the quantification, of elements (the analytes) in host
materials (the matrices) [1]. LIBS dates back almost to the invention of the laser [2] and has found application in a
wide range of sectors [3], spurred on mostly by its inherent simplicity. In essence, every element has a unique
optical spectrum (signature or fingerprint) allowing it to be identified by a simple wavelength measurement, and
quantified by a complementary intensity measurement. The use of a laser for elemental excitation has many other
advantages, remote/standoff operation, spatial scanning, no sample preparation, etc. extensively discussed in
literature [3].
