Z-200: The Premier Handheld LIBS


The Z-200 is the most portable, high performance LIBS analyzer ever created. It’s advanced technology includes on-board argon purge to deliver quantitative results; laser burst surface cleaning to eliminate grinding or surface prep; laser rastering for improved precision. It’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.

The Three “Must Have’s” for Alloys
& Other Materials Analysis


1

Argon Purge



The Z is the ONLY handheld LIBS with an integrated, user-replaceable argon purge. As any OES user will attest to, operating in an argon purge environment delivers 10x or more intensities, thus yielding far superior precision and limits of detection compared to air-based LIBS. In fact a major reason why the Z-200 can precisely analyze fine distinctions in aluminum alloys, and stainless, iron base and nickel superalloys, is due to the precision advantage from argon purge. 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.

Cleaning Mode



Dirty scrap? Oxidized or dusty metal components? The Z features novel cleaning mode to eliminate the need for grinding or surface prep – a critical requirement and something no other handheld laser unit offers. Cleaning mode fires the laser at 50 Hz (50 shots/second). After 0.2 sec 10 laser blasts have obliterated surface contamination, then the Z takes data from the cleaned surface. The Z delivers the same answer whether the surface is clean or dirty!

Rastered 2D Laser



Ok LIBS has been around for about 30 years in a laboratory package, and there’s been hundreds of scientific papers published about the technology. It’s well established that to obtain the best precision, the analyzer should test several locations on the sample, and average the results. The best explanation we’ve seen is that the laser is so focused (50 um) that even for alloys, the device should average several spots. This “must have” from the research community is fully integrated into the Z. It automatically moves the laser to several different locations on the sample in tenths of a second and averages the result.

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.

The new Z features a large display with 3X the brightness of the previous version. It’s easy to read in any lighting condition including direct sunlight.

Ergonomics

Ergonomics

The new Z is exceptionally well-balanced, with a specially designed ergonomic grip that offers all-day testing without operator fatigue.

Spectrumicon

Spectrometer

The Z uses a patented stack-spectrometer design. Its unique design offers a wide wavelength range and yields the best resolution of any handheld LIBS. The Z-200 has a standard range of 190 nm – 615 nm. The Z-200 can measure the emission of every element from hydrogen (H) to uranium (U) with the exception of: H, F, Br, Cl, N, O, S, Rb, Ce and K*.
*K: For potassium, the best line is > 615 nm. K can be measured with the Z-200 but only for cases where the concentration is greater than 1-2% and there is very little iron interference.

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.

No Fragile X-Ray Detectors
Unlike XRF analyzers, there’s no sensitive detector element near the front window. The Z uses a virtually impenetrable “tough as Pyrex” quartz window. Because LIBZ collects light in the visible and ultraviolet spectral region, rather than x-ray region, a durable, thick window may be used so long as it’s transparent to visible and UV light. Light traverses this quartz window, then into a well-protected spectrometer. You will not be able to break this detector window!

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.”
