For this purpose, high-energy, focused short-pulse laser radiation is used to ablate material from the surface of a sample, whereupon a light-emitting plasma of atoms and ions is formed under localized heating of several 10,000 \u00b0C. The expanding plasma initially emits non-specific deceleration and decay lines shortly after ignition. Shortly after ignition, the expanding plasma initially emits non-specific bremsstrahlung and recombination radiation (continuous spectrum). After a few 100 ns, the excited atoms and ions recombine, emitting a line spectrum &#8211; comparable to a fingerprint. Spectral analysis with a high-resolution spectrometer enables the chemical composition of the sample to be determined.<\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"609\" src=\"https:\/\/www.ltb-berlin.de\/en\/wp-content\/uploads\/2025\/01\/LIBS-1024x609.png\" alt=\"\" class=\"wp-image-1995\" srcset=\"https:\/\/www.ltb-berlin.de\/en\/wp-content\/uploads\/2025\/01\/LIBS-1024x609.png 1024w, https:\/\/www.ltb-berlin.de\/en\/wp-content\/uploads\/2025\/01\/LIBS-300x178.png 300w, https:\/\/www.ltb-berlin.de\/en\/wp-content\/uploads\/2025\/01\/LIBS-768x457.png 768w, https:\/\/www.ltb-berlin.de\/en\/wp-content\/uploads\/2025\/01\/LIBS-1536x913.png 1536w, https:\/\/www.ltb-berlin.de\/en\/wp-content\/uploads\/2025\/01\/LIBS.png 1800w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n<\/div>\n\n\n<div style=\"height:40px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\">What can LIBS do?<\/h2>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>LIBS is one of the few methods with which it is possible to simultaneously measure a large number of chemical elements to determine the atomic composition of a material sample. In contrast to other methods such as X-ray fluorescence analysis (XRF), this includes in particular the light chemical elements. All qualitative element information is assigned directly to the measured line spectrum with the help of spectral databases. The quantitative analyses are based on calibration measurements of the analyte with different concentrations in reference materials. Depending on the analyte-matrix combination, element concentrations in the lower ppm range can be determined.<\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"960\" height=\"542\" src=\"https:\/\/www.ltb-berlin.de\/en\/wp-content\/uploads\/2025\/01\/Unsere-Kollegen-von-LTB-China-zu-Besuch-in-Berlin.webp\" alt=\"LTB China colleagues visit Berlin and work on the CORALIS system.\" class=\"wp-image-867\" style=\"width:629px;height:auto\" srcset=\"https:\/\/www.ltb-berlin.de\/en\/wp-content\/uploads\/2025\/01\/Unsere-Kollegen-von-LTB-China-zu-Besuch-in-Berlin.webp 960w, https:\/\/www.ltb-berlin.de\/en\/wp-content\/uploads\/2025\/01\/Unsere-Kollegen-von-LTB-China-zu-Besuch-in-Berlin-300x169.webp 300w, https:\/\/www.ltb-berlin.de\/en\/wp-content\/uploads\/2025\/01\/Unsere-Kollegen-von-LTB-China-zu-Besuch-in-Berlin-768x434.webp 768w\" sizes=\"auto, (max-width: 960px) 100vw, 960px\" \/><\/figure>\n<\/div>\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading has-text-align-left\">LIBS &#8211; for which applications?<\/h2>\n\n\n\n<div style=\"height:30px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>LIBS has a wide range of possible applications.
