Laser Induced Breakdown Spectroscopy is known as LIBS. It is an analytical method for figuring out a material’s elemental makeup.
The surface of a sample is abraded by a highly concentrated laser in handheld LIBS analyzers. Atoms and ions that have been electrically stimulated come together to form a plasma.
These atoms leave behind distinctive light emissions as they return to their ground states, which are referred to as “unique fingerprints”.
Handheld LIBS analysis is a fantastic tool for both quantitative and qualitative evaluations because these “fingerprints” are unique for each element.
A quick, portable, in-situ atomic spectroscopy technique called laser-induced breakdown spectroscopy (LIBS) is used to detect the concentration of main and trace elements in solid, liquid, or air samples as well as to capture the chemical composition (fingerprint) of a substance.
In addition to information about the quantities of all naturally occurring elements, each LIBS spectrum also includes information about the atomic structure of the substance and some isotopic ratios.
Based on the laser wavelength, power, the characteristics of the material itself, and how well the laser relates to the material, LIBS is a spot analysis technique that produces laser ablation craters that are on the order of 3 diameter.
Due to the fact that LIBS is a spot analysis method, it is possible to assess spatial changes in material composition as well as to average shots taken at numerous sites on the materials to determine a bulk composition.
The Global Handheld Laser Induced Breakdown Spectroscopy Market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
A short-lived, high-temperature plasma is created by the ablation of atoms from the sample surface using a powerful laser pulse as the energy source.
In general, plasma temperatures are higher than those with enough energy to excite electrons in their outer orbitals.
The excited electrons in the plasma decay to lower-energy orbitals when the plasma cools, releasing photons whose wavelengths are inversely proportionate to the energy difference between the excited and base orbitals.
Each element can be stimulated to a large number of states, which results in a large number of emission wavelengths. The LIBS spectrum includes photons that are emitted by plasma molecules as well.
Laser-Induced Molecular Isotopic Spectrometry is a technique for measuring isotopic ratios by measuring the slightly varied wavelengths of photons that various isotopically composed molecules release.
The majority of laboratory and portable LIBS systems gather plasma photons through a lens close to the plasma and send them via fibre optics to the spectrometer.
The ChemCam instrument set on NASA’s Mars Science Laboratory Curiosity employs a different technique known as stand-off LIBS.
The sample used for stand-off LIBS analysis is placed a distance of several metres from the actual instrument, and photon emission is recorded by a telescope and sent to the spectrometer by fibre optic.
Since LIBS is a quick, portable method that doesn’t require sample preparation and offers in-the-moment analysis, it has been used in a wide variety of applications.
