The Z-901 features an all-new ergonomic design, a 0.5 lb. weight reduction down to about 3.5 lbs. (1.6 kg), improved heat dissipation, and completely updated software and processing electronics.

The Z-901 also leads the way featuring the first-ever “dual burn” technology. Users can test with the 901 either using an “air burn” method or using argon-purge for applications requiring higher precision and lower limits of detection.

The Z-901 uses a single spectrometer to cover the wavelength range of 200 – 440 nm. It is factory calibrated for a suite of 15-20 elements, depending on application.  Or operators may use the accompanying ProfileBuilder software package to customize to specific elements, their own calibration standards, and spectral processing.  The Z-901 can be setup to measure the emissions of any element EXCEPT Li, Na, H, C, N, O, Cl, Br, F, Ce, Rb, S. Common factory-calibrated applications include alloy, mining and environmental analysis, typically for beryllium in soil.

Z-901 CSi

The “CSi” is a dedicated unit for measuring carbon and silicon in steels and stainless.  It is the ideal tool if you own handheld XRF units and want to continue to use those for measuring common alloy elements such as Cr, V, Mn, Ni, Cu, Mo, Nb, etc.  but need the occasional carbon and/or silicon measurement.  The CSi opens up a very cost-effective option for many NDT professionals that have older XRF units and may only want to add in C and Si measurements in order to determine carbon equivalents (CE), verify L versus H-grade stainless or include a carbon measurement with low RE steels.


The Z-902 “C” is a dedicated NDT/PMI analyzer for carbon content and a wide range of alloys and alloy bases.  It features 2 spectrometers (instead of one in the 901) to extend the spectral range down to 190 nm with high resolution, specifically to measure carbon content in steels, stainless and other alloys.  The Z-902 is the analyzer of choice globally for the measuring carbon content in alloys, and carbon equivalents.  It is also factory calibrated for a suite of 15-20 elements in 7 common alloy bases: aluminum, steel, stainless, nickel, cobalt, titanium and copper bases.  Additional bases or calibrations may be added by the factory or the user.

Nearly 1,000 Carbon Units in service globally in every refinery and inspection company.


Analyzes every element in the periodic table.

The Z-300 is the LIBS of choice for applications in geochem, mining, oil & gas. It is our 3-spectrometer system, spanning a wavelength range of 190 nm – 950 nm. This range allows for the entire periodic table to be analyzed including critical elements such as S, H, the halogens and others. Like the Z-200, the Z-300 is factory calibrated for specific applications in mining and environmental applications. Examples include lithium in brines and hard rock, beryllium, boron and carbon analysis, fluorine, and sodium in soils or other materials. Operators may also use the accompanying PC software to set up their own calibrations for a variety of material types – glasses, polymers, archaeological and forensics samples, and many others.

Uniquely SciAps Product Features

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

Uniquely SciAps Product Features



The Z-900 Series uses a patented stack-spectrometer design that delivers wide wavelength range and high resolution – superior to any other handheld LIBS. Depending on your application, the 900 Series can be purchased with 1-3 spectrometers.  The 3-spectrometer Z-903 range is 190 nm – 950 nm. In addition to the elements measured by the Z-902, this wider wavelength range also measures: H, F, Br, Cl, N, O, S, Rb, Cs and K.


The SciAps Z-900 Series offers dual cameras.  A wide-area lens “macro-camera” provides for photo-documentation of samples tested and can read bar codes or QR codes for sample identification.  The internal camera allows pinpoint viewing and aiming of the laser for sample analysis. The internal  camera augments the power of LIBS analysis. The laser is automatically focused to < 100 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.



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.

Data Sharing & Connectivity

The Z is built on Google’s Android Platform and offers compatibility and connectivity to smartphones, tablets and other devices via the Android SHARE feature.  It’s also available with Cloud-based data sharing, data merging between multiple instrument platforms, and report generation.  It 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.

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!

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.


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

Sciaps Onebox Z-901 CSi LIBS and X-550 XRF

X-ray and laser together in “One Box”

The SciAps X and Z make the perfect complement for elemental analysis. The X analyzes transition and heavy metals with great precision, and is ideal for bulk sample types like alloys, soils, liquids, powders. The Z is ideal for low atomic number elements like Li, Be, B, C, Na, F even down to hydrogen. And the Z, with it’s integrated targeting camera and 100 um beam spot, is better suited for micro-analysis. The One-Box delivers optimal analysis across all elements and sample types, for bulk analysis or micro-analysis.

The X and Z also operate on the same battery, use the same charger and other accessories.

Smallest and Lightest

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 Grinding, except for Carbon

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.”
