The Z

A handheld that handles carbon content for L grade stainless!

The Z is the only handheld on the planet that delivers PMI for L grade, straight grade and H grade stainless as well as carbon steels and cast irons. It’s the ONLY laser (LIBS) with high enough precision to do NDT/PMI across all alloy bases. The Z features blistering speed and highly precise alloy analysis. Besides steels and stainless, it excels at aluminum alloys due to its performance on Mg, Si, Li, Be, B and other key alloying elements. The key to the Z? A powerful, high frequency laser, and on-board argon purge.

What’s Hot for the Z?


The world’s only handheld analyzer that delivers carbon content in stainless, steels and cast irons … yes, even L grades.

FAC (Flow-accelerated corrosion)

Need to measure down to 0.03% Cr in carbon steels for FAC?

Major Applications



Alloy material verification for on-shore & off-shore rigs.



Pipeline safety: Fast, in-ditch measurements of carbon and carbon equivalents. Material verification per API 5L, PHMSA “Mega Rule.”



PMI for carbon steels, L, and H grade stainless and nickel alloys. Residuals (Cr, Cu, Ni), including carbon. Carbon and carbon equivalents in welds and materials.

SciAps Pipeline App

The Pipeline App

Now in use by most major pipeline operators.

The Pipeline Safety App automates the testing procedure for carbon and CE in pipeline steels and welds, to reduce operator error. Designed for the PHMSA “Mega Rule.”

Argon Purge

Ask any OES user – LIBS is an OES method, it just uses a pulsed laser rather than a spark source. The key to precise alloy chemistry with OES is argon purge. Argon CartridgeArgon purge yields 10x or more signal strength and improved detection limits compared to air-burn methods. For carbon, because the 193.1 nm emission is so deep in the UV, the boost with argon is closer to 100x. Without argon, it simply wouldn’t be possible to achieve needed detection limits or measurement precision on C, Si, Cr and other transition or heavy metals, which are critical for reliable NDT/PMI testing. How does the SciAps argon purge work? SciAps delivers portability for argon purge. With our highly efficient Optipurge design, the user-replaceable canister in the handle delivers typically 600 tests. Costs are about a penny per test, as argon canisters cost about $6 each. Compare this to OES, where the argon costs are 10-15 cents per test, and that’s with a large, cumbersome argon tank. When not in use, the canister is sealed to the regulator, so no gas is consumed. Don’t need portability? Use our regulator attachment that mates to a larger belt-mounted argon canister or a standard stationary tank typical of spark OES analyzers.

Why the Z for NDT/PMI?


Carbon and Carbon Equivalents

Carbon ElementThe Z-200 C+ can now analyze carbon content in stainless, steels and cast irons. The Z also calculates carbon equivalent (CE) numbers. The Z is the only handheld analyzer in the world capable of providing carbon and CE measurements. Check out our Carbon ApNote for all the details.

Residual Silicon for In-service Carbon Steel Components

The Z measures silicon down to 0.05% in a 3-second total test time. It’s now accepted by several major refineries for silicon analysis concerned about sulfidic corrosion. In fact, the Z is the only handheld LIBS unit to offer quantitative analysis and achieve acceptance for these demanding applications.

The Best Performance for Aluminum and Magnesium Alloys

LIBS – especially the Z – analyzes aluminum and magnesium alloys with the greatest speed and precision of any handheld technology. If your focus is the most precise and fastest sorting of these types of alloys, then the Z is the only choice.

Flow-accelerated Corrosion (FAC)

If you need to test for FAC, especially in a power plant with onerous X-ray regulations, then the Z is a great choice. We’ve got dozens of users in the power industry, and great references – just contact us. The Z has a Cr LOD of 0.03% in a 3-second test.


The X

The world’s lightest, smallest, fastest, high precision alloy gun. Weighing barely 3 lbs., it’s lightning fast, and can be used all day long without fatigue. More than 90% of all alloys can be identified in 1 second with excellent precision, and the most challenging super-alloys can be identified in 3 seconds. Yes, many “PMI guns” will test alloys. But only the X is built on the Android platform for real-time data exporting anywhere on the planet, with efficient test data input and reporting. If you do PMI, especially at more than one location, you really need to check out the X before you replace your existing analyzer.

What’s Hot for the X?

Fast aluminum alloy sorting

Our new turbo tube and Aluminum App sorts even low Mg materials (0.3%) in 2 seconds.

Sulfidic Corrosion

The X is accepted for low silicon analysis in carbon steels. Measure < 0.1% Si in 5 seconds.

An X for Every Performance and Price Need



The flagship for high performance PMI. The X-250 delivers fast, precise measurements of low concentrations of Si, P, S, Mg, Al, Ti, V and Cr. It’s field proven to measure Si below 0.1% in 5 seconds, for sulfidic corrosion applications. Fast P and S measurements in steel and stainless, and Ti and V for 5L. Need to test aluminum alloys? The X-250 measures 0.3% Mg in just 2 seconds – precise Mg and Si measurements are critical to aluminum alloy verification.



The workhorse. For daily NDT/PMI activities where blazing speed on Si, P, S, Mg, and Al isn’t mission critical, the X-200 is the ideal choice. Fast, lightweight, and the best value on the market for high performance XRF testing.



Features the cost-effective PIN technology. If you only require verification of common stainless, nickels, other high temp alloys, brasses, and bronzes, then save money and get the X-50.

Why the X for NDT/PMI?


Size, Speed and Precision

The X is small, lightweight, ergonomically packaged, and offers blistering speed and high precision. The X delivers the fastest, most precise results available with handheld X-ray for stainless, high temp alloys and aluminum alloys. The performance is especially good on the lower atomic number elements Mg, Si, Al, S and P due to our highly optimized X-ray tube and detector design. The results with beam 2 are exceptional, including S and P in stainless, carbon steels and copper alloys, Mg and Si in aluminums, and Si and Al in red metals.

Total Upgradeability – Defy Obsolescence

The SciAps 90+ Guarantee

If you buy a more basic (and lower priced) X model, you can always upgrade your analyzer to a higher performing version by paying the difference in price, plus at most 10% additional. It’s why we call it the 90+ guarantee. You get at least 90% of your original purchase credited, now matter how old your analyzer, provided it’s in working condition.


The Ultimate in Portability

The ONE BOX exploits the best of X-ray and the best of LIBS via a compact, affordable package of analyzers with shared accessories like batteries, charger and cables. In fact, the ONE BOX delivers optimal performance for virtually every alloy and element for less money than a comparable spark OES system.
