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

General Materials Analysis
The Z plus our tablet/desktop software, ProfileBuilder, lets you configure the Z for virtually any element in any material type. Choose lines, build calibration curves and models with total flexibility.
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.
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.
The new Z is exceptionally well-balanced, with a specially designed ergonomic grip that offers all-day testing without operator fatigue.
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.
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.
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
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.
SciAps Z – Top 10 Advantages
The ONLY LIBS that offers Dual-Burn Operation
The Z features on-board argon purge for high precision analysis. Users may also run the Z in air-burn if your testing requires less precision or you have restrictions on gas canisters. 50 years of spark optical emission have proven the analytical superiority of argon purge!
Protect your Confidential Materials Chemistry
The Z includes desktop/tablet software allowing a user (password protected) to modify calibrations, elements analyzed, grade IDs and various spectral pre-processing. Customers can keep their proprietary materials proprietary!
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!
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.
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.”
