Quick Model Guide



Range (nm)




200 – 440 Common elements for most applications including light elements Be, B.
Excludes C, Li, Na.
Air-burn and argon-purge tests for alloy analysis, mining and environmental, general analytical studies.

Z-901 CSi

190 – 240 C and Si Dedicated to measuring C, Si in steels, stainless and (future) Ni alloys.

Z-902 Carbon

190 – 440 Elemental range of the Z-901 plus carbon.  High-resolution spectrometer targets carbon in alloys, including L-grade stainless, plus other alloy bases. 

Z-902 +

190 – 625 Analysis of the Z-901 but extends spectral range to include Li, Na and C for non-alloy applications. Extends analytical range to include Li in alloys, ores and brines, non-alloy measurement of C, and Na. Not for carbon in steels, stainless or other alloys (use Z-902 Carbon).


190 – 950 Above plus H, N, O, Cl, F, Br, Ce, Rb and S. Mostly for geochem, researchers, academic institutions, forensics or specific analytical applications. Measures emissions of every element through transuranics.


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 Profile Builder 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 Z-901 applications include alloy, mining and environmental analysis, typically for beryllium in soil.


Z-901 CSi

SciAps “CSi” is dedicated to measuring carbon and silicon in steels and stainless. Perfect for busy XRF users. Want to continue to use XRF for measuring common alloy elements such as Cr, V, Mn, Ni, Cu, Mo, Nb, etc.,  but need the occasional carbon and/or silicon measurement? CSi opens up a very cost-effective option for many NDT/PMI professionals who rely on XRF units but may want to add 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.

Z-902 Carbon

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


The Z-902+ features two spectrometers (instead of one in the 901) to extend the spectral range down to 190 nm and out to 625 nm. This allows the Z-902+ to measure lithium in aluminum alloys, plus Li, Na and C in non-alloy materials such as ores, brines, soils. Without a dedicated high-resolution spectrometer for carbon, this unit does not include sufficient resolution in iron-base alloys to meet NDT/PMI requirements.


Analyzes every element in the periodic table.

The Z-903 is the LIBS of choice for applications in geochem, mining, oil and gas. It is our three-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. 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


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 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, SciAps 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 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!


The SciAps Z-900 Series offers dual cameras.

  • A wide-area lens “macro-camera” documents samples and reads bar codes or QR codes for sample identification.
  • The internal camera augments LIBS analysis with pinpoint viewing and aiming for sample analysis. The laser is automatically focused to <100 µm beam size, without requiring any external, intensity-killing collimation commonly found with XRF. Precisely strike many types of samples: Welds can be analyzed in multiple locations when examining weld chemistry changes across the weld; 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

SciAps Z Series is built on Google’s Android platform for compatibility and connectivity to smart phones, 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 that eliminates the tedious process of downloading and importing data. The powerful processor offers Wi-Fi and Bluetooth communications, and GPS is enabled.

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

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.”
