Meet the Z: The world’s premier handheld LIBS (Laser induced breakdown spectroscopy) analyzer featuring the most advanced technology ever created in a handheld elemental analyzer. The Z-903’s spectrometer range covers 190 nm – 950 nm. It offers instant analysis of every element in the Periodic Table, for nearly all materials, anywhere on the planet. The analyzer features pre-configured Apps for specific applications (alloys, geochem, etc.). Or users may create their own custom analysis models, element lists, and calibrations. The Z-903 includes a full-featured desktop or tablet software package with spectral pre-processing, chemo-metrics, emission line identification for any element and quantitative calibration setup. The Z handheld LIBS is perfect for the lab, the classroom and the field.
The Z features our proprietary wide range, high resolution spectrometer stack design.Both standard and extended range versions are available:
The Z is the only handheld LIBS that offers both argon and air-based operation It is well established that operating in an argon gas atmosphere increases the LIBS signal by 5x-10x or more, depending upon wavelength. Users can optionally operate the Z with it’s on-board argon supply enabled. If you don’t need the precision or sensitivity, simply turn it off. The cost of the argon is approximately 1₵ per test.
The Z has a replaceable argon cartridge inside the handle, with on-board regulator. Simply unscrew the used cartridge and replace. Helium gas also available for enhanced halogen analysis
The Z combines an XY user-controllable laser raster along with integrated high-resolution camera. For heterogeneous samples, users may setup and view the raster pattern, to analyze only specific zones within a sample.
For homogeneous (bulk) samples, the best LIBS results are obtained when the laser beam is moved to multiple locations on the sample, and averages the results over multiple locations. The Z was designed with a computer controlled XY stage to move the laser beam in two dimensions and automatically rasters and averages data.
What is cleaning? The Z may be configured to fire multiple laser shots at the same location, thus burning off surface contamination including dirt, oils, corrosion, etc., prior to data-taking shots. Subsequent laser shots at the same location are used for elemental analysis. The Z is totally user-settable for one or more cleaning shots, followed by repeat data shots, and XY rastering to a new location on the sample. For many samples, cleaning shots are critical to obtaining repeatable, precise analysis.
The Z may be operated in either a gated or ungated mode. For the most quantitative analysis, gating is the recommended operation because it largely eliminates the Brehmstrahlung background produced by the early stages of the plasma. By reducing the background, the signal—to—noise (SNR) is enhanced, yielding both better limits of detection and higher precision.
For some operations, operators only care about maximizing total intensities. In these cases, the Z may be operated (and calibrated) in ungated mode. For some Apps, calibrations are provided for both gated and ungated operation. Please inquire with SciAps.
