A single laser pulse vaporises a tiny fraction of the sample surface, forming a high-temperature micro-plasma. As this plasma cools, emitted light reveals the atomic fingerprint of the sample. When paired with high-resolution spectrographs, such as our LTB ARYELLE<\/a> series, LIBS captures the full spectral signature all the way from UV to NIR. It can simultaneously detect lighter and heavier elements in a matter of milliseconds.<\/p>\n\n\n\n Unlike X-ray Fluorescence (XRF<\/a>), which struggles with low-atomic-number elements, LIBS detects light elements easily. Elements such as lithium, beryllium, boron, carbon, hydrogen, and sodium<\/strong> produce strong optical emission lines, making LIBS essential for battery research, metallurgical sorting, and geological surveys.<\/p>\n\n\n\n LIBS operates directly on raw samples. There is no need for acid digestion, vacuum preparation, or complex cutting:<\/p>\n\n\n\n Because each laser pulse consumes only nanograms to micrograms of material, the crater left behind is often microscopic (tens of micrometres wide). This yields distinct spatial advantages:<\/p>\n\n\n\n Understanding the physical boundaries of optical emission spectroscopy ensures realistic expectations and optimal system setup.<\/p>\n\n\n\n To achieve reliable quantitative results, match your setup to these critical variables:<\/p>\n\n\n\n LTB Aryelle Spectrometer Family ideally suited for LIBS Applications<\/p>\n\n\n\n <\/p>\n","protected":false},"excerpt":{"rendered":" Introduction At LTB Lasertechnik Berlin GmbH, we specialise in high-performance Echelle spectrometers tailored specifically for Laser-Induced Breakdown Spectroscopy (LIBS).
