What is Laser Induced Breakdown Spectroscopy (LIBS)?
Laser Induced Breakdown Spectroscopy (LIBS) is a rapid chemical analysis technology that uses a short laser pulse to create a micro-plasma on the sample surface. This analytical technique offers many compelling advantages compared to other elemental analysis techniques. These include:
A sample preparation-free measurement experience
Extremely fast measurement time, usually a few seconds, for a single spot analysis
Broad elemental coverage, including lighter elements, such as H, Be, Li, C, N, O, Na, and Mg
Versatile sampling protocols that include fast raster of the sample surface and depth profiling
Thin-sample analysis without the worry of the substrate interference
A typical detection limit of LIBS for heavy metallic elements is in the low-PPM range. LIBS is applicable to a wide range of sample matrices that include metals, semiconductors, glasses, biological tissues, insulators, plastics, soils, plants, soils, thin-paint coating, and electronic materials.
So how does LIBS Work?
The main physical process that forms the essence of LIBS technology is the formation of high-temperature plasma, induced by a short laser pulse. When the short-pulse laser beam is focused onto the sample surface, a small volume of the sample mass is ablated (i.e. removed via both thermal and non-thermal mechanisms) – in a process known as Laser Ablation. This ablated mass further interacts with a trailing portion of the laser pulse to form a highly energetic plasma that contains free electronics, excited atoms and ions. Many fundamental research projects have shown that the plasma temperature can exceed 30,000K in its early life time phase.
When the laser pulse terminates, the plasma starts to cool. During the plasma cooling process, the electrons of the atoms and ions at the excited electronic states fall down into natural ground states, causing the plasma to emit light with discrete spectral peaks. The emitted light from the plasma is collected and coupled with an ICCD/Spectrograph detector module for LIBS spectral analysis. Each element in the periodic table is associated with unique LIBS spectral peaks. By identifying different peaks for the analysed samples, its chemical composition can be rapidly determined. Often, information on the LIBS peak intensities can be used to quantify the concentration of trace and major elements in the sample.
With the advancement of powerful chemometric software for LIBS data analysis and with steady progress in understanding laser ablation fundamentals, today’s analytical researchers are applying LIBS effectively for both quantitative and material discriminatory analysis for a wide range of sample matrices.
Applied Spectra harnesses LIBS technology with its state-of-the-art elemental testing devices. We deliver solutions that are fast, reliable, precise and environmentally friendly. Our instruments are adaptable to a variety of environments from field testing, to manufacturing floors, to laboratory settings. Contact Datech Scientific Limited discuss more.
