The world’s first handheld analyzer to deliver carbon content just got better.












Meet the Z-902 +

The Z-902 + 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-902 + can use on-board argon purge for high precision analysis or QuickSort for rapid material sorting or grade identification with air-burn. Depending on the element, the LIBS signal is 2x-10x higher when operating in argon purge versus air-burn.
‍
The analyzer uses two spectrometers to extend the  wavelength range to 190 – 620 nm. The instrument 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-902 + can be set up to measure the emissions of any element. Common factory-calibrated Z-902 + applications include alloy and aluminum.












Alloy Analysis




Alloy: Argon-purge for high precision and improved detection limits. Many customers use argon-purge to analyze and sell mill-ready aluminum scrap.

‍QuickSort: Air-burn for rapid material sorting or grade identification.







The Z-902 + for alloy analysis measures 15-20 elements in 7 common alloy bases, including aluminum, stainless, iron, copper, titanium, nickel and cobalt bases. Other bases may be added for a small fee, or users may add their own calibrations.

High-purity Argon and Purge

Argon purge is essential for quantitative analysis with LIBS and OES, and for carbon it’s critical. SciAps patented Opti-Purge technique is a key component for measuring carbon accurately. Opti-Purge delivers argon exactly where it’s needed and uses about 1,000 times less argon than a spark OES, allowing for a user-replaceable canister. Operators can analyze up to 600 samples with the argon canister for most alloy testing, and 125-200 samples for carbon analysis.






Analysis Averaging

Multi-shot averaging and data rejection are critical to getting the best carbon tests. The combination of these two features, known as analysis averaging, allows the operator to (optionally) reject test data with significant point-by-point discrepancies then automatically create a final result.






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 user of spark OES knows, sample prep is critical for carbon analysis—a good grind and a good pre-burn are as critical for LIBS as for spark OES. SciAps high energy and high rep rate laser (50 Hz) rapidly burns off surface contamination in order to provide a good analysis.






Micro-camera and LED Spotlight

Proper alignment is critical to getting good analysis. Take out the guess work with SciAps micro-camera and LED Spotlight. The camera shows the sample in high resolution and ensures that the instrument is positioned correctly; LED Spotlight shows exactly where the laser will burn the sample. Get a good burn every time.






Laser Raster

Rastering is critical for accurate carbon tests with LIBS. The Z moves the laser to 6 distinct locations and analyzes each spot for 0.5 seconds for every 3-second test. The laser is typically 50 um diameter beam. On that scale, micro inclusions in the alloys and the grain structure of the alloy can impact the analysis. By averaging across six unique locations, the system collects data that is representative of the alloy, not just an individual location.









Argon: Cost of Operation

Argon costs just pennies per test, far less expensive than spark OES and much more convenient.  What does that mean in real terms? It depends if you are doing carbon tests or general alloy tests.  You can expect to get about 100 tests per canister for carbon, and 600 tests for general alloy; if you buy your argon canisters in the 10 pack, it will cost you $65 ($6.50 each), which means 6 cents, or 1 cent per test, respectively. Don’t always need carbon? Then add on the SciAps “Dual Burn” capability for non-carbon tests in air.
