Elemental Analysis by Laser Spectroscopy (LIBS): Rapid and Precise Element Identification
What is Laser LIBS Spectroscopy?
Laser-Induced Breakdown Spectroscopy (LIBS) is a fast, non-destructive geochemical analysis technique for identifying the elemental composition of a material. Used in many fields, including industry, geology and environmental analysis, LIBS offers great flexibility and real-time analysis.
LIBS spectroscopy relies on the use of a pulsed laser to ablate a tiny amount of material and form a high-temperature plasma. The light emissions from this plasma are analyzed to determine the nature and concentration of the elements present.
LIBS analysis applications
Geology
- Rapid identification of minerals, rare earths, etc.
- Trace element analysis in rocks.
- Chemical mapping of geological formations.
- Geosteering for drilling deep well drains.
Environnement
- Soil and pollution analysis.
- Water quality control.
- Detection of heavy metals (Pb, Hg, Cd, As, Cr, Ni, Zn, Cu, Sb, Co).

LIBS vs. XRF: why choose LIBS?
LIBS spectroscopy and X-ray fluorescence (XRF) are two elemental analysis techniques, but they differ in several key features.
- Types of elements detected: LIBS can detect all elements, including light elements such as hydrogen, lithium, boron and carbon, whereas XRF is less effective on these elements.
- Speed and mobility: LIBS offers real-time analysis with portable equipment, ideal for on-site applications, whereas XRF is often more static and requires longer acquisition times.
- Spatial resolution: Thanks to its focused laser, LIBS enables more precise analysis of microscopic areas, unlike XRF, which offers broader resolution.
- No ionizing source: Unlike XRF, which uses X-rays that may require special precautions, LIBS relies on no ionizing source, making it safer to use.
In short, LIBS is particularly advantageous when rapid, mobile detection and analysis of light elements is required, making it more flexible and versatile than XRF.
FAQs on Laser LIBS Spectroscopy
How long does LIBS analysis take?
Analysis is virtually instantaneous, with results obtained in a matter of seconds.
How accurate is LIBS?
The technique offers ppm detection for many elements, but accuracy depends on material type and analysis conditions. INGEN has developed specific in-house calibrations for quantifying elements to ppm.
How much does LIBS analysis cost?
Prices vary according to the number of samples and analysis requirements. Contact us for a customized quote.
