What is LIBS?
Laser-induced breakdown spectroscopy (LIBS) is an elemental analytical technique best suited for light element detection and characterisation. It is performed by focusing an energetic laser pulse onto the surface of a solid or liquid, or into sample volume of a gas or liquid. The resulting microplasma contains excited molecular and atomic species from the bulk sample, as well as ablated particulates. The excited species then emit light at unique wavelengths.
By using a spectrometer, light can then be collected and parsed to a computer. Each element has a unique emission spectrum, which means all elements can be detected with LIBS. Laser-induced breakdown spectroscopy can be remotely conducted in real time and requires no sample preparation or radiation licensing.
Unlike XRF, handheld LIB spectroscopy is better suited for light element detection – such as Aluminum (Al), Lithium (Li), Magnesium (Mg), and Beryllium (Be).
Applications for LIBS
Positive Material Identification (PMI)
Positive Material Identification refers to the fast and non-destructive testing (NDT) method for verifying the chemical composition of metals. Accurate analysis rests on reliable positive material identification which underpins quality control and quality assurance. The potential for material mix-ups and the need for traceability are legitimate concerns at every step in the manufacturing process.
The chemical products obtained from petroleum by refining are known as petrochemicals. Elements which present in low concentrations such as nickel, chromium and copper are used in small quantities in carbon steels for petrochemicals.
Our range of LIBS instruments excel at measuring and analysing these alloying elements.
Scrap Metal Sorting
There’s never been a more critical time to ensure accuracy and transparency when it comes to metal sorting in your scrap metal recycling process. And, with ever-increasing competition and supplier demands, industry leaders know maintaining profitability in a volatile metal-pricing environment is crucial.
Regardless of your application, our range of LIBS analysers are available to do the job, ensuring the alloy grade and composition meet your specifications.
