The Z-200 from SciAps, Inc. for metals recycling and scrap metal sorting offers speed on the low atomic number elements including Mg, Si, Al, Li and Be–elements the firm says handheld X-ray fluorescence (HHXRF) instruments measure slowly or not at all. 

The Z’s unique, advanced laser technology also delivers the speed and accuracy for red metals, stainless and high temp alloys.

SciAps, a Boston-based instrumentation company specializing in handheld and portable analytical instruments, recently released an advancement to their proprietary laser design for the Z-series handheld LIBS analyzers. The updated laser operation (patent pending) operates at 50 Hz for sample surface preparation. It fires 10 laser shots in 0.2s at the same location to burn off surface material, then relaxing to 10 Hz operation for gated spectral data collection–critical for low concentration measurements. The company’s patented argon purge+ laser raster technology can provide precise alloy chemistry in a matter of seconds. The precise chemistry provides much finer alloy grade identification than simple sorting devices. The Z is the only handheld LIBS device that uses internal argon purge.

“SciAps unique combination of rapid-fire sample cleaning, argon purge and rastered laser have been the keys to our success in the broader alloy markets,” SciAps CEO Don Sackett said. “With the argon purge we’ve gone on-site and demonstrated excellent performance even on demanding nickel superalloys, whereas other handheld LIBS devices that operate without argon only analyze aluminum alloys. Our new high-energy, high-speed laser cleaning also overcomes the persistent problem of surface contamination. In the early days of handheld LIBS, test results would vary based on if a sample was ground and by how much. As we’ve demonstrated numerous times with our new laser fire technology, we can test virtually any alloy material including the dirtiest scrap, without grinding or sample preparation.”

Founded in 2012, SciAps is headquartered in Woburn, Mass.
