Quantitative elemental imaging of heterogeneous catalysts using laser-induced breakdown spectroscopy

Quantitative elemental analysis by laser-induced breakdown spectroscopy

Laser-induced breakdown spectroscopy (LIBS) has been popular in elemental analysis for various kinds of samples due to its rapid and in-situ measurement using simple equipment. However, quantitative analysis by LIBS is still inferior to conventional element analysis methods in sensitivity and accuracy. In this paper improvement in LIBS is attempted applying computational processing to low-resol...

Laser Induced Breakdown Spectroscopy for Semi-quantitative Elemental Analysis in Soils and Marine Sediments

The Laser-Induced Breakdown Spectroscopy (LIBS) technique is based upon the analysis of the atomic emission lines generated close to the surface sample. The emission is observed once a laser pulse is focussed on the surface, where the very high field intensity initiates an avalanche ionisation of the sample elements, giving rise to the so-called breakdown effect. Spectral and time-resolved anal...

Laser Induced Breakdown Spectroscopy

Laser-induced breakdown spectroscopy (LIBS) is a powerful analytical technique that can be used for the detection and characterization of materials. In LIBS, a focused laser beam is used to generate a plasma plume on the surface of solid and liquid samples or inside the sample volume of gases, liquids, and aerosols. Each excited atom in the plasma emits a unique set of spectral lines, particula...
