Cyanide Molecular Laser-Induced Plasma Spectroscopy

Stand-off Planetary Surface Analysis Using Laser-induced Breakdown Spectroscopy and Laser-induced Plasma Ion Mass

Introduction. Characterization of useable planetary materials will require high sampling throughput. Although remote observations from orbiting spacecraft provide spatially wide coverage, they do not, by themselves, provide sufficient information for materials utilization purposes. On the other hand, active rover-based in-situ analyses can provide detailed geological information but can be very...

Simple Laser-Induced Fluorescence Setup to Explore Molecular Spectroscopy

We will demonstrate a relatively simple, affordable and highly visual experiment to explore molecular spectroscopy by measuring the laser-induced fluorescence (LIF) spectrum of the iodine molecules at room temperature. Iodine is a uniquely suited molecule for LIF measurements since it conveniently absorbs about 20,000 lines in the 490to 650-nm visible region of the spectrum and serves excellent...

Laser Induced Breakdown Spectroscopy

Laser-induced breakdown spectroscopy (LIBS) is a powerful analytical technique that can be used for the detection and characterization of materials. In LIBS, a focused laser beam is used to generate a plasma plume on the surface of solid and liquid samples or inside the sample volume of gases, liquids, and aerosols. Each excited atom in the plasma emits a unique set of spectral lines, particula...
