LIBS (Laser Induced Breakdown Spectrometry) is primarily an elemental analysis technique based on the high-temperature spark
(plasma) produced by a sufficiently energetic laser pulse.
Light produced by the LIBS plasma is collected and spectrally dispersed in much the same manner as other analytical atomic methods (ICP-OES, spark-OES).
LIBS technique can be used to essentially detect any element in the periodic table and is applicable to almost any sample type.

Laser-based atomic spectrometry resulting from a fluence exceeding the ablation threshold of a wide range of sample matrices has been practiced for decades. The first of two currently popular applications for quantitative spectrochemistry was predicated on using the laser as a sampling tool to ablate samples and sweep the liberated particles into an inductively coupled plasma (ICP) where the dry aerosol experiences dissociation into atoms and ions and, in the case of emission spectrometry, thermal excitation to produce a laser ablation ICP emission spectrum (LA-ICP-ES).
LIBS has also been practiced for decades and, in deja-vu parallel, also experienced an initial period of optimistic growth that triggered several commercial start-ups. Quantitative direct solid sampling LA-ICP-MS evolved to respect intrinsic issues like fractionation and limitations based on the availability of standards and found specific applications like mineral mapping and geochronology via isotope ratios. In similar fashion, LIBS has also found certain specific “killer apps” – one being the unique capabilities in the lithium-ion battery industry where elements like F, O, and H are very important and there is literally no other direct solid analytical method.
There are a few major advantages that ought to emerge from the recent acceleration of LIBS research and development.
LIBS (Laser Induced Breakdown Spectrometry) as a technique has unique characteristics when compared to traditional elemental analysis methods and a highly flexible yet standardized approach is necessary to address the wide range of potential applications.

The Sci-LIBS MHE-266-RSV employs a high energy Nd:YAG pulsed laser to deliver 60 mJ of energy at 266 nm via the fundamental, frequency quadrupled beam. The Laser Excitation Module (LEM) can also accommodate lower energy primary laser sources as well as secondary lasers for double pulse (DP), laser induced fluorescence (LIF) and other scaleable modes of operation or experimentation.
The system employs three Sciencetech SC-12 sample chambers housing the energy delivery module (EDM), the sample/target module (STM), and for the large-sample stand-off module (SOM).
The EDM provides 3 X beam expansion, beam cleanup, and beam attenuation. The motorized beam attenuation module (BAM) can continuously vary the energy (0 -95%) of the primary 266 nm beam (PB) and simultaneously generate a secondary 266 nm beam (SB – alternate polarization) that is used for the Stand-off Module (SOM).
The second SC-12 is the STM and provides for XYZ translation control for research (small) samples. The STM contains the control and gas plumbing for air, helium or argon chamber environments. Low pressure chamber atmospheres are provided by optional vacuum accessories for more fundamental plasma studies.
Within the SC-12 STM, use of specialized reflective optics and lens configurations define the optical collection module (OCM). Off-axis parabolic UV-coated mirrors can provide 10 X to 100 X more light collection when compared with the usual objective-to-FOC method. However, in addition to a conventional spectrometer slit, it is possible to add FOC pickups to feed additional spectrometers
