Applied Spectra is ready to showcase J200 Tandem LA-LIBS technology at Pittcon 2019. Laser Ablation (LA) Technology for direct solid sample analysis is now catching on for many industrial applications. The advances in LIBS, LA-ICP-MS and Tandem LA-LIBS (simultaneous LIBS and LA-ICP-MS) are allowing the analysts to measure more elements over a greater dynamic range of concentration (ppb to %) with a single pulse of laser sampling. The LA technology is ideal for getting spatial information of elements in your sample quickly. If you have been doing the following work with ICP-MS/OES, GD-MS/OES, XRF, EMPA and Spark/Arc OES and struggling to meet all of your measurement needs, we love to connect with you at Pittcon 2019.
- Lighter element analysis (Li, B, Mg, Na, K, etc) for glass samples
- Carbon analysis in steel sample
- Hydrogen analysis in metal alloys
- F and other halogen element analysis in geological samples
- High throughput mining sample analysis- need to eliminate acid digestion
- Li-ion battery analysis that requires elements that are outside capability of XRF and SEM-EDS (i.e. binder distribution)
- Forensic analysis that requires high sensitivity based on very little amount of sample
- Geological mineral analysis that requires information about H,B, Li, C, O, F, Cl, P, etc along with trace level REE and transition metals
- Hard to handle sample analysis -nuclear materials
- And so much more
At our booth #1655, we will perform the live demo of the J200 Tandem LA – LIBS Instrument and Clarity Tandem data analysis software.
Visit us and meet our world class scientific team to find out how our technology can help to overcome the challenges that you are facing with your analysis!

Over the past fifty-plus years, laser ablation (LA) has developed into a mainstay technology for direct solid sampling analytical chemical analysis. The driving forces include rapid analysis, no acid digestion, spatial resolution, 3D mapping and the ability to measure every element in a sample by combining detection modalities. These attractive features has helped propel LA over other technologies for analysis, especially because laser ablation sampling does not require vacuum and can be applied to any sample matrix. Laser ablation is the sampling process not the analysis; a short-pulsed laser beam removes mass (sampling) for subsequent analysis. The ablated mass is first heated into a luminous optical plasma at the sample surface that is spectroscopically measured (LIBS – Laser Induced Breakdown Spectroscopy) for elemental and isotopic content. As the plasma cools, the mass condenses to a fine aerosol which can be transported to an Inductively Coupled Plasma (ICP) for sensitive and precise isotopic analysis. The ICP with mass spectrometry (ICP-MS) is ideal for trace analysis of isotopes, especially for the heavier elements. LIBS is ideal for analyzing major concentrations and light elements, including O, N, H and the halogens. These two detection modalities complement each other nicely. Optical emission from the luminous plasma monitored simultaneously with the ICP-MS detection provides complementary elemental and isotopic analysis of the sample, with every laser pulse. Our new technology LAMIS (Laser Ablation Molecular Isotopic Spectroscopy) measures isotopes in laser plasmas at atmospheric pressure from molecular emission band spectra in addition to atomic and ionic line spectra. Simultaneous LIBS, LA-ICP-MS, and LAMIS provides the ability to measure every element and isotope on the periodic chart for every laser pulse ablation. With these excellent features, software has to evolve to unravel the optical and mass spectra for accurate and precise analysis. This presentation will describe attributes of laser ablation chemical analysis with powerful software for intelligent elemental, isotopic and molecular information extraction.
