Laser ablation (LA) with optical (LIBS) or mass (ICP-MS) detection is an excellent technology for direct sample (solid, liquid, gas) analysis. Benefits of laser ablation include no sample preparation, no consumables, every sample, real-time analysis, standoff (LIBS) measurements, and more. Knowledge of ablation processes, reliable system components, and development of methods has led to excellent performance metrics (accuracy and precision) of this technology.
