The LIBS2500+ laser-induced decay spectrometer is a detection system that allows real-time qualitative measurement of elements in solids, solutions, and gases. This broad-spectrum, high-resolution system provides a spectral analysis range of 200-980 nm, with an optical resolution of ~0.1 nm (FWHM). A high-intensity, pulsed laser beam is focused on the sample surface over a range from a few centimeters to one meter. A 10-nanosecond-wide laser pulse excites the sample. When the laser fires, the high temperature of the laser generates a plasma. As the plasma decays or cools (~1.0 µs after the laser pulse), excited-state atoms in the plasma emit light at wavelengths different from those of the sample elements. The wavelength range is 200-980 nm. The detection system can simultaneously use up to 7 HR2000+ high-resolution miniature fiber optic spectrometers for simultaneous measurement (reading and writing data), each with a 2048-pixel linear array CCD. The LIBS2500+ detector collects the broad spectrum from 200-980 nm and transmits it to the application software to display the data. The LIBS2500+ has two laser options, both products of Big Sky, a pioneer in the laser industry. Laser ablation and plasma formation are very unique to different samples, so different samples have different energy requirements. In most applications, we use a Q-switched 1064 nm Nd:YAG laser. For multiple functions, we recommend using a 200 mJ laser with an attenuator, which can adjust the laser energy according to the sample. The choice of laser energy and wavelength will depend on the material and the degree of damage allowed. The LIBS-LASER uses a 50 mJ CFR Nd:YAG laser, targeting metal and thin-film samples. The LIBS-LAS200MJ uses a 200 mJ CFR Nd:YAG laser, suitable for glass and high-OH materials. For liquid samples, a dual-wavelength laser can be used; oxidizing substances in the sample will slow the formation of plasma, so another laser is needed to enhance plasma formation.

Applications

LIBS technology can be applied to many fields: Environmental monitoring (soil contamination, particulates) Material analysis (metals, plastics) Forensic and biomedical research (teeth, bones) Military and defense (explosives, biochemical weapons) Art restoration/preservation (pigments, jewelry/ancient metal artifacts)

Key Features

Broad-spectrum, high-resolution spectral analysis (0.1 nm optical resolution, wavelength range 200-980 nm) Real-time qualitative measurement PPb and picogram sensitivity Can be applied to material analysis, environmental monitoring, forensic and biomedical research, art restoration, and more Traditional LIBS detection systems provide a narrow spectral range, whereas the LIBS2500+ is the first system to provide broadband spectral analysis. Thanks to good safety protection, users can perform on-site real-time measurements, including in harsh industrial, chemical, and biomedical environments, without sample preparation. Because the LIBS2500+ uses Ocean Optics' HR2000+ high-resolution miniature fiber optic spectrometers, the system is portable and can be connected to a computer via a USB port. The LIBS2500+ is easy to use and can be connected to any 32-bit, USB-compatible Windows computer. It connects to a PC through a single USB port for plug-and-play operation. We provide the OOILIBS application software for operating the LIBS2500+ and triggering the laser. Through the OOILIBS application software, users can perform spectral compensation and data saving. The OOICOR-related software, developed by the University of Florida, provides instant material identification when using the LIBS2500+.
