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.
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.

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.

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 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.
