The Z-200 C+ is a dedicated analyzer for alloy analysis including carbon content. It analyzes carbon content in stainless, down to 0.007 ppm, for dependable separation of L and H grades. The C+ also analyzes carbon steels, including carbon equivalents (CE) for weldability.

  • Delivers PMI for most alloys in 1 second with excellent precision.

    Some NDT-PMI applications require longer tests, or multiple beam tests. Our Android apps-based platform provides pre-configured, dedicated apps to make quality testing by every operator as easy as using a smartphone – including apps for residuals (API 751), sulfidic corrosion (API 939), API 5L and other testing. Read X-550 Alloy Specifications.

  • Optimized for key PMI applications like Residuals and Sulfidic Corrosion.

    PMI Applications ScreenFor many PMI applications, fast tests are sufficient for verification of alloy grade and geochemistry. More complicated applications require longer test times or multi-beam operations (one beam optimized for transition and heavy metals; the other for low atomic number elements Mg, Si, Al, P and S). Dedicated apps ensure testing follows correct procedures, such as recommended test times and X-ray beam settings. For example, the Residuals app defaults to 15-second test times due to the need to measure Ni, Cr and Cu at <0.03% each (sum <0.15%) and Nb and V at <0.02%. The Sulfidic Corrosion app is preconfigured to require two-beam tests in order to measure Si down to 0.03% in steels. 

  • Designed for NDT, PMI users to access hard-to-reach test locations and welds.

    Perfectly balanced, light weight, and articulate, you can test all day long without fatigue. The narrow footprint permits total access to virtually any test location and weld.

Sulfidic corrosion per API 939



  •  Great on high temp alloys and precious metals.

     Like most XRFs, the -550 provides fast, precise chemistry on the wide array of high temperature alloys, stainless, red metals and precious metals.  What’s different is the toughness of this metal-framed analyzer, that’s yet incredibly light weight (< 2.8 lbs.) and in perfect balance. Use it for sorting all day long without fatigue. The on-board cell phone camera (macro camera) allows for photo-documentation of materials tested, and the Bluetooth label printer provides instant hard copy labels with time/date stamp, grade ID and chemistry. 

  • Featuring the Aluminum App: Sort all your Al alloys in 1-2 seconds.

     If you’re a scrap processor, the one reason to buy the X-550 over the X-505 is the blazing speed and accuracy on aluminum alloys. The X-550 features our patent pending Aluminum App.  It sorts your aluminum alloys in 1-2 seconds, including those alloys that differ only by magnesium (Mg) content.  Grades that were either impossible to sort with other XRFs or take minutes of testing time, such as 3003/3004/3005, cast 356 and 357, and 2014/2024, are just a few examples. You can now sort many similar Al grades economically. See our “Guide to Aluminum Alloy Sorting.”

  • Contaminant Phosphorus & Sulfur.

    The high powered X-ray tube in the X-550 provides fast analysis of phosphorus (P) in copper and P and sulfur (S) in steels and stainless, allowing you to economically upgrade your copper and ferrous material based on low P and S levels.  The X-550 is 3x faster on P and S than is the X-505 or competing XRFs. Faster testing times make upgrading material for low P and S more economical.

  • Tramp Elements.

    Scrap processing has moved beyond just grade sorting. Many consumers now demand analysis on tramp or residual elements in common steel, nickel and copper alloys. The X-505 is optimized for low detection limits on common tramp elements, including Cr, Ni, Cu, V, Nb, Mo in steels, Pb and Bi in nickel alloys, and various undesired elements in copper alloys. 

Sort your widest variety of Al alloys in 1-2 seconds!

Put a STOP to your downgrades from mixing aluminum alloys that differ by Mg or Si.


Now available for exploration and ore grade control applications. The benefit of the X-550 for geochemistry is fastest possible analysis on low atomic number elements in ore/soil samples including Mg, P, S, Al, Si, Ca and K. Contact us for details about our exploration apps for elemental analysis and pathfinder elements. SciAps XRF analyzers are utilized worldwide by many major exploration companies and mining laboratory services companies.  Also available with compact test stand for closed-beam operation. Read X-550 Geochemistry Specifications.   


Environmental Soil

The X-550 may be equipped with apps for elemental analysis of environmental soils. The analysis package includes the 8 RCRA metals and 11 of the 12 EPA priority pollutant metals (excepting beryllium – use our LIBS for that).  The X-505 complies with the long standing EPA Method 6200.


General Analytical


Do you have a unique analytical applications? The X-505 can be equipped with our Empirical App, allowing the user to set up unique beam conditions, define specific elements of interest and create custom calibrations. For analytical requirements outside the realm of alloys, ores and polymers, the X-505 plus Empirical App offers complete flexibility for unique or proprietary analytical requirements. .

The Essentials for Carbon Analysis in Alloys with Handheld LIBS

High-purity Argon and Purge

Argon purge is essential for quantitative analysis with LIBS and OES, and for carbon it’s critical. SciAps patented argon purge technique for LIBS is a key component for measuring carbon accurately, and at the concentration levels needed for L-grade stainless. The laser beam is about 100 um in diameter, thus a very small purge volume is needed for the argon purge. The Z uses about 1,000 times less argon than a spark OES, so that the argon source is a user-replaceable canister located in the Z’s handle. Operators can analyze up to 600 samples with the argon canister for most alloy testing, and 125-200 samples for carbon analysis. Carbon analysis requires averaging of several tests.


High Laser Pulse Energy and Frequency

The SciAps laser delivers 5-6 mJ/pulse on the sample, with a 50 Hz repetition rate. As any spark OES user knows, sample prep is critical for carbon analysis. The high energy and high rep rate laser (50 Hz) rapidly burns off surface contamination in order to get a good analysis. A good grind and a good pre-burn is as critical for LIBS analysis as it is for spark OES.



Laser Raster

Rastering is a must for accurate carbon tests with LIBS. The laser is typically 100 um diameter beam and even the best sample prep may not completely remove surface contamination on this distance scale. The Z moves the laser to 6 distinct locations and analyzes each spot for 0.5 seconds, for a 3 second test. The carbon algorithm then examines the resulting data from each location and can (optionally) reject test data with significant point-by-point discrepancies. The analyzer can be setup for manual or auto burn rejection. If a burn is rejected, the analyzer notifies the operator.
