LIBS: Understanding Its Capabilities and Applications

When exploring analytical techniques for surface analysis, Laser-Induced Breakdown Spectroscopy (LIBS) stands out. At LTB Lasertechnik Berlin GmbH, we provide the cutting-edge Echelle spectrometers that maximize the full potential of LIBS. To make an informed decision about whether LIBS is right for you, it’s crucial to understand both its strengths and limitations.

What LIBS Does very well:

Elemental Analysis: LIBS excels at determining the elemental composition of surfaces. By focusing a laser pulse, it creates a micro-plasma that emits light characteristic of the elements present. LIBS can identify and quantify a wide range of elements, especially light elements, providing valuable insights into the surface’s characteristics. LTB’s unique spectrometers are designed to capture this light with exceptional precision.

Rapid Sample Analysis: LIBS offers real-time or near real-time results, enabling quick decision-making and efficient analysis of large sample sets. This is particularly valuable in time-sensitive applications.

(Almost) Non-Destructive Analysis: LIBS is generally non-destructive, preserving the sample for further analysis or reference. This is crucial when working with delicate or valuable materials.

What LIBS Doesn’t Do so well:

Depth Profiling: LIBS primarily interacts with the surface layer, limiting its ability to provide detailed information about subsurface layers or depth-dependent elemental distribution.

Chemical Compound Identification: LIBS focuses on elemental analysis and may not provide detailed information about chemical compounds. While some compounds may exhibit unique spectral signatures, other techniques are better suited for complex compound identification.At LTB we have options to combine LIBS with Raman spectroscopy to overcome this limitation.

High Sensitivity for Trace Elements: LIBS may have limitations in sensitivity for trace elements compared to techniques like ICP-MS or AAS. However, LTB’s high-performance analysers are designed to push the boundaries of LIBS sensitivity.
