LIBSlab Measuring Instrument
The LIBSlab is a compact and easy to use measuring instrument for the qualitative and quantitative multi-elemental analysis by means of laserinduced breakdown spectroscopy (LIBS). Due to its modular design, the LIBSlab provides individual confi guration options to meet your requirements for a fl exible use of LIBS technology in the scientifi c and industrial sectors.
A modular based measuring instrument in compact design for the qualitative and quantitative multi-elemental analysis of material samples by means of laser-induced breakdown spectroscopy (LIBS).

Why LIBS?
|
The LIBSlab is a complete measuring system for the non-contact multi-elemental analysis by means of laser-induced breakdown spectroscopy (LIBS). It can be easily adapted to your specific needs by individually combining and customizing the modules sample chamber, spectrometer, laser and software - PC.
Sample chamber
The LIBSpector is a compact sample chamber for the LIBS analysis of solid, liquid and gaseous samples. It comes with a laser class 1 housing and is equipped with safety interlock, laser protection window for observation and exhaust flange for safe use. No additional laser safety precautions are therefore required at installation site. The beam of the laser, whose head can be incorporated in the chamber housing, is directed to the sample via telescope optics and generates a light emitting plasma. The plasma light is guided to the spectrometer via mirror and fiber optics. Sample mapping is provided by an integrated motorized XYZ stage that can easily be controlled either with the supplied XYZ joystick or by software. For precise sample positioning and focusing, a pilot laser and a real-time video monitoring based on a high-resolution CMOS camera are installed. Several sample holders for solid, liquid and gaseous substances provide universal application capability and can be adapted to your individual requirements.
Spectrometer
All spectrometers made by LTB Lasertechnik Berlin are based on a dispersion unit with echelle grating and prism and feature high-spectral sensitivities and excellent imaging qualities. The LIBS emission spectrum of a sample can be measured simultaneously from the UV to the NIR range by using a high-resolution spectrometer from the ARYELLE and DEMON series. In combination with different CCD-, EMCCD-, ICCD- and CMOS- detectors the spectrometers provide a wide range of customer applications.
| Laser For plasma generation, various Nd:YAG and excimer lasers with different wavelengths and pulse energies. The choice of the optimal LIBS laser setup depends on your individual application and can be made by yourself. Many years of experience gained with diverse laser types and manufacturers enable us to give you competent advice.

| Software and PC The operating and evaluation software Sophi developed by LTB Lasertechnik Berlin provides access to all device functions of the spectrometer-detector unit, the LIBSpector and laser via notebook or PC-based user interface. After transforming the detector information into wavelength-dependent intensity values, all lines of the gained LIBS spectrum are automatically analyzed with the integrated NIST atomic data base and qualitatively assigned to the corresponding elements. For quantitative multi-elemental analysis of unknown samples, calibrations with reference materials are a precondition. The implemented script-based control allows the automatization of recurring measuring and evaluation procedures and provides you maximum flexibility. Recalibration of the wavelength scale of the spectrometer-detector unit are easily performed with the auto-calibration function by using the included mercury lamp.
