Portable LIBS
A portable Laser-Induced Breakdown Spectroscopy (LIBS) device is a compact analytical instrument used for rapid elemental analysis of materials. It operates by focusing a single-plus high-energy Nd:YAG 1064 nm laser to vaporize a microscopic area of a sample at high temperature and the sputtered particles are broken down into a mixture of atoms, ions, and electrons.
Portable LIBS systems enable real-time, in situ, and with minimally destructive analysis and minimal sample preparation, making them especially useful in geology, mineral exploration, metallurgy, environmental studies, and cultural heritage investigations. Their mobility, speed, and ability to analyze full range of major, minor, and trace elements simultaneously and its low cost and easy operation have attracted the interest of several gem laboratories.
Bench-Top LIBS
A bench-top Laser-Induced Breakdown Spectroscopy (LIBS) system is a laboratory-based analytical instrument used for high-precision elemental analysis. It employs a high-energy Nd:YAG 1064 nm laser to ablate a microscopic area of a prepared sample, generating a high-temperature plasma composed of atoms, ions, and electrons.
Owing to its stable optical configuration and controlled measurement conditions, bench-top LIBS enables reliable quantitative and semi-quantitative analysis of major, minor, and trace elements, including light elements such as Li, Be, B, Cs, and Cl.
