November 10th, 2015 – SciAps, Inc., the leading provider of handheld analytical instruments, is releasing 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 1-2 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. Existing customers may upgrade their Z analyzers free of charge with an available firmware and software release, following in SciAps long-standing tradition of supporting early adopters.
“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,” said Don Sackett. “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.” SciAps has also released a series of demo videos showing the laser’s performance on a range of alloys including aluminum alloys, red metals, nickel and superalloys and titanium, links below:
