Z-300: Analyze The Entire Periodic Table

The Z-300 accomplishes what no other portable analyzer has done. It’s a handheld analyzer that measures every element in the Periodic Table.


The Z-300 is revolutionary. It’s the most portable, high performance LIBS analyzer ever created. Its advanced technology includes a stacked, high resolution spectrometer that spans from 190 nm – 950 nm, thus covering the emission lines for every element from H to U. The spectrometer can be operated in either gated or ungated mode. It uniquely features an on-board argon purge to deliver higher-precision, quantitative results; laser burst surface cleaning and rastering to eliminate grinding or surface prep and improved accuracy. The Z’s Android-based operating system is as friendly and intuitive as a Smartphone, and it supports numerous analytical Apps for a variety of sample types.

Spectrometer range: 190 nm – 950 nm.

Additional range compared to Z-200 model provides additional elements
H, N, O, F, Cl, Br, Rb, Cs, K, S.

The Three “Must Have’s” for Handheld LIBS

Argon Door Animation

1

Argon Purge



The Z is the ONLY handheld LIBS with an integrated, user-replaceable argon purge. Operating in an argon environment yields 10x or more boost in signal, particularly for emissions in the deep UV (190 nm 0 300 nm), where many elements are measured. Shown in the figure are two spectra from a stainless steel, with and without argon, demonstrating the large signal boost. Also available are larger belt-mounted canisters (4x the volume). Users may also connect the Z to industry standard stationary argon tanks with our optional package of bridge regulator and tubing.

Can I use the Z-300 without argon? Yes. All our LIBS units can be run with/without argon or with/without spectrometer gating. You’ll need to use our ProfileBuilder App to adjust the calibration curves however.

Calcium Concentration as a Function of Depth in the Sample

Example of surface preparation by the Z’s laser. Repeat shots, fired at 50 Hz, burn away surface material (calcium indicator) allowing analysis of underlying bulk substance.

Cleaning Mode Laser Technology
– Automates sample prep, offers depth profiling



The Z features novel cleaning mode to provide automated, user-settable surface preparation depending on the type of application. Cleaning mode fires 5-6 mJ/pulse laser shots at 50 Hz (50 shots/second) thus 5 cleaning shots every 0.1 sec. Users can choose the number of total cleaning shots, after which the Z will use subsequent shots for spectral data and analysis. For metal surfaces which may be dirty or contaminated, the standard setting is for 10 cleaning shots, whereas for soil samples, often only a few are used. The cleaning shot capability may also be used for depth profiling, for example, monitoring elemental concentrations as functions of depth into the sample. The laser focus is also under software control so that analysis continues into the depth of the material.

Rastered 2D Laser + Variable Focus



A large body of publications suggests the best LIBS precision is obtained when the laser is rastered, and results averaged over multiple locations. The Z takes rastering a step further for handhelds. It has an integrated XY stage, plus a Z-direction focus adjustment. In addition to factory-set rastering for specific applications (alloy, geochemical, etc.), the user may also setup their own raster pattern. A user can do a line scan, or even single spot analysis on an inclusion or vein of material. The laser spot size is approximately 50 um in diameter. The Z includes an illumination fiber which when aligned with the rastering, illuminates the location where the plasma will is created. With the software-controlled variable focus, a user can obtain analytical results as a function of sample thickness.

ProfileBuilder

Want Quantitative Results? Build Custom Calibrations for any element or sample type with ProfileBuilder

Profile Builder

The Z is pre-configured for certain applications such as alloy and mining. But it is designed for so much more. With our PC/Tablet software ProfileBuilder, users can build quantitative calibrations for practically any group of elements, for nearly every material type:

Polymers • Ceramics • Catalysts • Powders and more


How It Works

Users may enter assays of known materials for calibration, locate elemental lines after testing samples, calculate intensities and intensity ratios, perform spectral overlays, baseline subtractions and smoothing. Most users have known reference samples – often proprietary to their operations – to generate calibration curves for specific groups of elements. The calibrations are then easily pushed to the analyzer via USB or Wifi. Unknowns can then be tested for elemental chemistry using the calibration curves developed. ProfileBuilder supports polynomial fits to relate measured intensity ratios or intensities, to concentrations.

Uniquely SciAps Product Features


Safety

The Z features a sample detection system that yields the safety of Class 1 conditions.  If there’s no sample present, the laser will not fire a single pulse, meaning no stray laser light fired into empty space. If a sample is removed during testing, the laser immediately stops firing once the sample is ¼” or more away from the window.  Because the Z will not fire into empty space, it may be operated under Class 1 conditions, with proper training (ANSI Z136.1). Thus the Z provides the analytical advantages of a 3b laser in a device that may be operated in Class 1 conditions. This safety benefit is ONLY achievable with a milli-joule, low rep-rate laser. High rep rate class 3b lasers, like those featured in other LIBS devices, cannot operate with this safety mode.

Spectrometer

The Z-300 uses a patented stack-spectrometer design and includes an additional spectrometer compared to the Z-200. Its unique design offers both high resolution wide wavelength range – superior to any other handheld LIBS. The Z-300 wavelength range is 190 nm – 950 nm. In addition to the elements measured by the Z-200, this wider wavelength range also measures: H, F, Br, Cl, N, O, S, Rb, Ce and K.

lasericon

Laser

The key to good LIBS analysis is creating a good plasma. The best plasma’s come from the highest power densities on the sample. The Z’s PULSAR laser technology fires laser pulses in the 5-6 mJ/pulse range, at up to 50 Hz frequencies, with 1 ns wide pulses. It is well established that mJoule, rather than micro-joule laser pulses yield superior analytical results.

cameraandsharing

  • Camera/Video
The SciAps Z combines its high resolution camera and video capability with powerful Android features that enable photos or videos of test locations or samples to be taken and stored with results. This ability augments the power of LIBS analysis. The laser is automatically focused to < 50 µm beam size, without requiring any external, intensity-killing collimation commonly found with XRF. The Z’s camera can be used to precisely strike many types of samples. Welds can be analyzed in multiple locations when examining weld chemistry changes across the weld. The Z’s camera can hone in on particular regions for non-homogenous samples. Images are automatically saved with results for photo-documentation. And, the Android platform enables sharing of the data and high resolution images when collaborating with colleagues or reporting results.

  • Data Sharing & Connectivity
The Z is built on Google’s Android Platform to defy obsolescence and provide easy, intuitive operation. Android offers instant compatibility and connectivity to smartphones, tablets and other devices and avoids the tedious process of downloading and importing data – including the Android SHARE feature. The powerful processor offers Wireless, Bluetooth communications and is GPS enabled.

Battery

The newly designed Z uses much less power, and lasts 6+ hours on a single, lightweight battery. Plug in the AC adapter to recharge and power the analyzer. External battery charger and spare battery included

Auto Calibration

The Z monitors time and internal temperature, and automatically institutes a calibration as needed. This means no cal-check samples to carry around (and lose or get dirty). Reduces the likelihood of operator error by automating the calibration procedure.

Lightest, Fastest LIBS Analyzer

The latest Z is the lightest, fastest high performance LIBS analyzer. Perfectly balanced, you can test fatigue-free all day long. Wrist strap also included. Results shown in 1 second, full test time 3 sec.

No Sample Grinding

No Sample Grinding!

The Z uses a 50 Hz laser, firing 10 surface cleaning shots in 0.2 seconds to burn away surface contaminants, dirt, etc. The Z is the only LIBS unit proven to analyze even the dirtiest scrap without grinding. 

Z Raster Pattern

Beam Rastering

The Z rasters the laser to 6 different positions and automatically averages the results. Why do this? Because LIBS lasers are typically 50 um in diameter, and testing a single location may not average out inhomogeneities even in vacuum melt alloys. Also if the laser happens to hit an inclusion or embedded contaminant, an outlying result will be averaged out over the rastering. 50 years of LIBS scientific literature tell you that rastering is a “must have.”
