Product Announcement from StellarNet, Inc.
PORTA-LIBS-2000 and Plasma Monitor Configurations
The PORTA-LIBS-2000 is the first truly portable low cost analyzer that can be used for real-time qualitative measurements of trace elements. It can be used for dedicated applications in the field or just about anywhere. Portable high resolution EPP2000 spectrometers are integrated with a high intensity pulsed laser, and sample chamber, to permit UV-VIS- NIR spectral analysis of unknown samples. The portable instrument case is just 18 x 14 x 7 inches and operates via 12 volt adapter or battery. Detection requirements determine the number of required spectrometer channels. Up to 8 high resolution spectrometers can be attached via USB-2 computer interface with 0.1 or 0.2nm resolution.
PORTA-LIBS-2000 system-
The entire platform, including the laser, sample compartment, and trigger module measures 5 cm x 21 cm x 10 cm. Not shown is the battery pack or the laptop computer.

Laser Induced Breakdown Spectroscopy or LIBS has become the common acronym for element detection via laser induced plasma. This permits real-time qualitative identification of trace elements in solids, gases, and liquids via optical detection of elemental emission spectra. Using this technique, little or no sample preparation is required and calibration-free quantitative analysis has been reported without matrix effects.
High Resolution Spectrometers
The PORTA-LIBS-2000 spectrometers are miniature fiber optic instruments for UV, VIS, and NIR measurements in 190-1000nm spectral ranges. Each unit contains a high speed integrated digitizer with a 4K word spectral scan memory to provide instantaneous spectral capture from the highly sensitive 2048 element CCD detectors. Various models provide a choice of grating range and slit resolution to fit detection requirements. Fiber optic cables deliver the spectral signal from the sample chamber and use standard SMA 905 connections.
The spectrometer optics are exceptionally robust in a vibration tolerant modular design that has no moving parts. The detachable optics assembly and control electronics are protected inside a rugged metal enclosure, suitable for portable applications.
Several units may be daisy-chained via USB-2 hub allowing for expandable configurations. The LHR high resolution spectrometers have double the resolution (0.1nm) over LSR standard models (0.2nm) with the same grating. The LSR models on the other hand have twice the wavelength range of the LHR allowing for a smaller number of channels when application requirements permit. Most elements have plasma emission spectra in the 200-500nm UV-VIS range, leaving just a few.
Free SpectraWiz and SpectraWiz ID
The SpectraWiz software provides element identification via spectral database for qualitative measurements. Samples can be quickly measured and saved to log-file. Options allow customization of spectral search algorithms. Custom compound element libraries can be created or searched.

Power and InterFace
Portable spectrometers include a USB-2 interface cable and +5VDC power adapter for 120VAC-60H (light sont transformers with U.S. style 2 prong plugs). For usage outside the U.S.A., we offer an upgrade to universal power adapters. If you don't have a USB-2 port, connecting the spectrometer to a second EPP printer port on your computer is most convenient and recommended. For portable notebook computers that don't have a USB-2 port or an EPP capable printer port, we offer the PCMCIA card style EPP interface. in the 500-925nm VIS-NIR range.
Each PORTA-LIBS-2000 spectrometer includes fiber optic cable interface to sample chamber and high speed USB-2 computer interface with hub when needed. Additional cables are provided for battery operation and laser synchronization.
Spectrometer optics include CCD detector upgrade for UV, order sorting filters, and slit. Optical alignment of each channel allows for 5nm of overlap outside of specified range. SpectraWiz software integrates all optical channels into single spectral graph for elemental analysis and display.
