Latest Advances in Laser Ablation Direct Solid Sampling
This short course is designed to provide an overview of direct solid analysis techniques provided by laser ablation. These techniques include LA-ICP-MS (Laser Ablation-Inductively Coupled Plasma-Mass Spectrometry, LIBS (Laser Induced Breakdown Spectroscopy) and Tandem LA-LIBS in which LA-ICP-MS and LIBS work together to obtain complementary elemental and isotopic information. The effective sampling approaches for using LA for bulk, inclusion, depth profiling, and spatially resolved 2D and 3D mapping analysis will be highlighted. Finally, popular and emerging applications of LA-ICP-MS and LIBS will be overviewed. These example applications include the analysis of metal alloys, energy storage materials, geological samples, plastics, bio-tissue, soils, and forensic trace evidences.
This course is for the lab managers who use ICP-MS and ICP-OES instruments for routine sample analysis and are looking to develop direct solid analysis for their sample work. The course can also benefit geologists, metallurgists, forensic scientists and analytical researchers with information on latest LA instrumentation trend and data analysis tools.

Dr. Jhanis J. Gonzalez C. obtained his PhD degree in chemistry from the Universidad Central de Venezuela in 2002. Following his Ph.D years, he spent two years as a post-doc researcher at Lawrence Berkeley National Laboratory (USA). Since 2004, he has been a staff scientist at Lawrence Berkeley National Laboratory (Berkeley, CA) and also has served as the Application Lab Director of Applied Spectra, Inc. (Fremont, CA). His analytical research interest include fundamental mechanisms of laser-material interactions (ablation) generated by nanosecond and femtosecond pulsed lasers and their impacts on LIBS and LA-ICP-MS based on all platforms of ICP-MS instruments. He is also involved in the development of analytical methods for applications in energy, environmental, geochemistry, biological and metallurgy industries. Dr. Gonzalez has over 50 manuscripts published.
