Laser Ablation–Based Chemical Analysis Techniques: A Short Review
by Dr. Jhanis Gonzalez
Laser ablation is a powerful approach to chemical analysis because of its versatility. It has advantages in chemical analysis including direct characterization of solids, no chemical procedure of dissolution, which reduces the risk of contamination or sample loss, analysis of very small samples not separable from solution analysis, and determination of spatial distribution of elemental composition.
This article, recently published in Spectroscopy, reviews the most common laser ablation techniques such as LIBS (Laser Induced Breakdown Spectroscopy) and LA-ICP-MS (Laser Ablation Inductively Coupled Plasma- Mass Spectrometry), as well as introduces the exciting possibility of LAMIS (Laser Ablation Molecular Isotopic Spectrometry).

Laser ablation in analytical chemistry is a sampling process; a short-pulsed laser beam is used to remove mass from a sample for subsequent ICP-MS/OES analysis. Laser ablation is also used to create luminous plasma whose emission spectra can be analyzed for elemental analysis (LIBS). This short course overviews laser ablation fundamentals and processes that impact the analytical performance of both LA-ICP-MS and LIBS.
This course will present the latest advance to combine optical and particle detection during laser sampling to perform simultaneous LIBS and LA-ICP-MS analysis (Tandem LA – LIBS). Various examples of analytical applications and data analysis will be used to bring practical perspective on effective use of these techniques.
