A Method for Resolving Overlapped Peaks in Laser-Induced Breakdown Spectroscopy (LIBS)

Applied Spectroscopy, 2013
Spectral peak overlapping is a basic problem in analytical data processing of laser-induced breakdown spectroscopy (LIBS). Curve fitting is the typical method of resolving overlapped peaks. For preventing ambiguous fitting, appropriate initial values must be known.

Laser-induced Breakdown Spectroscopy (LIBS) in Forensic Sensing

2019
Laser-induced Breakdown Spectroscopy (LIBS) is considered a versatile, multi-elemental, non-contact, powerful atomic spectrometry method, which can provide elemental composition data for practically any sample in a virtually non-destructive sampling and without or minimal sample preparation.

Laser Induced Breakdown Spectroscopy (LIBS) of Kidney Stones

1988
Laser induced shock wave lithotripsy (LISL) using a flashlamp pumped dye laser produces a plasma on the stone surface which leads to a bright flash of intense light. The high temperature of the plasma vaporizes the stone material leading to electronically excited atoms and ions.

Measuring Total Soil Carbon with Laser‐Induced Breakdown Spectroscopy (LIBS)

Journal of Environmental Quality, 2001
ABSTRACTImproving estimates of carbon inventories in soils is currently hindered by lack of a rapid analysis method for total soil carbon. A rapid, accurate, and precise method that could be used in the field would be a significant benefit to researchers investigating carbon cycling in soils and dynamics of soil carbon in global change processes.

Laser-induced breakdown spectroscopy (LIBS) for food analysis

Trends in Food Science and Technology, 2017
Background Laser-induced breakdown spectroscopy (LIBS) is an atomic emission spectroscopic technique which uses a focused pulsed laser beam to generate plasma from the material. The plasma contains atoms, ions and free electrons which emit electromagnetic radiation as the plasma cools down.
