Z-300 Handheld LIBS Analyser
The Z-300 is revolutionary. 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 Three “Must Have’s” for Handheld LIBS
The Z-300 is the 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 – 300 nm), where many elements are measured. Also available are larger belt-mounted canisters (4x the volume). Users may also connect the Z-300 to industry standard stationary argon tanks with an optional package of bridge regulator and tubing.
Can you use the Z-300 without argon? Yes. All SciAps’ LIBS units can be run with/without argon or with/without spectrometer gating. You’ll need to use the ProfileBuilder App to adjust the calibration curves however.
Cleaning Mode Laser Technology – Automates sample prep, offers depth profiling
The Z-300 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-300 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-300 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-300 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.
The Z-300 Software – The Flexibility of a Laboratory Analyser, the Portability of a Handheld
Instant qualitative analysis of the entire Periodic Table, in seconds, with Element Pro.
Test anything! With the ElementPro App, shoot any sample to get an instant snapshot of what elements are present. ElementPro scans the entire spectrum, compares with the SciAps library of LIBS emission lines, and instantly shows what elements are present in the sample, with qualitative relative abundances.
The Z-300 is pre-configured for certain applications, however it is designed for so much more. With the 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 analyser 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.
The Z-300 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-300 will not fire into empty space, it may be operated under Class 1 conditions, with proper training (ANSI Z136.1). Thus the Z-300 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.
The Z-300 is exceptionally well-balanced, with a specially designed ergonomic grip that offers all-day testing without operator fatigue.
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.
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-300’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.
The Z-300 features a large display with 3X the brightness of the previous version. It’s easy to read in any lighting condition including direct sunlight.
The Z-300 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-300’s camera can be used to precisely strike many types of samples. Welds can be analysed in multiple locations when examining weld chemistry changes across the weld. The Z-300’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.
The Z-300 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.
Data Sharing & Connectivity
The Z-300 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.
The Z-300 uses much less power than previous models, and lasts 6+ hours on a single, lightweight battery. Plug in the AC adapter to recharge and power the analyser. External battery charger and spare battery included.
