Z-200 Handheld LIBS Analyser

The Z-200 is a handheld, high performance LIBS analyser.

The Three “Must Have’s” for LIBS Analysis

Argon Purge

The Z-200 is a 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. Also available are larger belt-mounted canisters (4x the volume). Users may also connect the Z-200 to industry standard stationary argon tanks with an optional package of bridge regulator and tubing.

Cleaning Mode

The Z-200 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-200 takes data from the cleaned surface. The Z-200 delivers the same answer whether the surface is clean or dirty!

Rastered 2D Laser

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 analyser 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), the device should average several spots. This “must have” from the research community is fully integrated into the Z-200. It automatically moves the laser to several different locations on the sample in tenths of a second and averages the result.

Unique Features:


The Z-200 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-200 will not fire into empty space, it may be operated under Class 1 conditions, with proper training (ANSI Z136.1). Thus the Z-200 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-200 is exceptionally well-balanced, with a specially designed ergonomic grip that offers all-day testing without operator fatigue.


The Z-200 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.


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-200’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 analysers, there’s no sensitive detector element near the front window. The Z-200 uses a virtually impenetrable “tough as Pyrex” quartz window. Because LIBS 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!


The Z-200 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-200 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-200’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-200’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.

Auto Calibration

The Z-200 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-200 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-200 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.
