LIBS, which stands for Laser Induced Breakdown Spectroscopy, is a technique that utilizes a high-energy laser pulse to instantaneously irradiate the surface of a sample, generating plasma and analyzing the emitted spectrum to determine the sample's elemental composition. LIBS technology offers several advantages:
No sample pre-treatment required: LIBS technology can directly analyze samples in various states, including solids, liquids, and gases, without the need for cumbersome sample pre-treatment steps, saving time and cost.
Wide range of analyzable elements: LIBS technology can analyze nearly all elements, including light elements like hydrogen, carbon, nitrogen, etc., and heavy elements that are difficult to analyze using other methods.
Fast analysis speed: LIBS technology offers rapid analysis, typically completing an analysis in just a few seconds.
Unaffected by matrix interference: LIBS analysis results are not affected by the matrix, enabling accurate determination of the sample's elemental composition.
LIBS technology finds extensive applications in various fields, including:
Industrial inspection: LIBS technology is applicable in quality inspection of raw materials, intermediate products, and final products in industries like metallurgy, chemicals, electronics, and food.
Environmental monitoring: LIBS technology can be employed for pollutant monitoring in environmental samples such as soil, water, and air.
Geological exploration: LIBS technology is utilized for elemental analysis of geological samples like ores and rocks.
Archaeological artifact authentication: LIBS technology aids in elemental analysis and authenticity identification of archaeological artifacts.
Medical diagnosis: LIBS technology facilitates elemental analysis of ex vivo tissue samples, assisting physicians in disease diagnosis.
