PULSAR Laser Technology
Opti-Purge™ Argon Purge Technology
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.
As shown spectrally, in an argon environment rather than air, signals are many times larger, thus yielding superior analytical performance.
Sophisticated Laser Rastering
and Sample Cleaning
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.
For a rock sample, for example, the user can view the sample from the integrated camera, and customize the raster pattern to perform LIBS analysis over a specific region.
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.
Shown are a gated and ungated spectrum from the same material. Note that the gated spectrum exhibits far lower background, thus improving the SNR and allowing for lower limits of detection. The ungated signal is substantially higher (as is the background). Ungated operation is best used for higher concentration analysis where speed rather than precision is desired.
An Android, App-Based
The Z runs on the Android operating system. Various calibrations are easily added as independent Apps, much like a Smartphone. Have a custom application? Use the SciAps Empirical App, and the included ProfileBuilder desktop software, to create your own calibrations and testing methods for any element, in virtually any material. In the near future we’ll be offering additional Apps via our web-site, and the ability for users to create and share their own testing methods via their own Apps.
Check out our Element Pro App
Element Pro includes an on-board library of LIBS emission lines for every stable element in the periodic table. Simply shoot a sample, and get a list of elements present, based on the Z’s peak finding algorithm. Element Pro also provides a qualitative estimate of relative abundance based on measured line strengths in a variety of materials. Tap on an element to get a zoomed spectral view identifying the lines present. Element Pro is an ideal App for quickly testing materials to discover elements present, without the need for quantitative calibrations.

Handheld Raman Analysis:
In the lab or in the field – the Inspector Series Raman is a great tool for teaching or field studies. Raman spectroscopy is a highly selective method for uniquely identifying a wide range of organic compounds and minerals. The Inspector series can be used with SciAps’ own libraries, external chemical libraries, or users may generate their own.
Portability when you need it, or dock it to the SCOPE for small particle analysis, with integrated microscope and video.
Novel 1030 nm technology that suppresses fluorescence, and thus expanding the range of compounds you can analyze.
Advanced chemo-metrics package available to support advanced spectral analysis and quantification.
We frequently loan handheld LIBS units for a few weeks or a month to academic researchers from the U.S. and Canada, so that they can perform a study or field analysis anywhere in the world. Laser-induced breakdown spectroscopy is often a preferred technique, especially for students, since operators do not have to deal with the regulatory complexities of X-ray fluorescence analyzers. And our accompanying ProfileBuilder software provides operators complete freedom to modify laser and spectrometer parameters and generate their own calibrations. You’re not limited to factory-imposed calibrations or unchangeable multi-variant techniques.
Contact us (email@example.com) with a brief description of what you want to measure. As your work progresses, we’d appreciate continued updates. Don’t worry, we understand that you can’t compromise a future publication. On an as-available basis, we’ll get you the analyzer, train you at a regularly scheduled time (often via GoTo Meeting or Skype but in-person works too). The goal is to raise awareness of the amazing world of applications available to handheld LIBS and XRF. Please note at this time we must limit the loaner program to researchers working at U.S. and Canadian institutions. However, researchers from these countries may travel globally with the analyzer.
