DIESEL PARTICULATE ANALYSIS USING SEM-EDX AND LASER-INDUCED BREAKDOWN SPECTROSCOPY

Diesel Particulate Analysis Using Sem-edx and Laser-induced Breakdown Spectroscopy

In this paper, composition analysis using scanning electron microscopy/energy-dispersive Xray spectroscopy analysis (SEM-EDX) and laser-induced breakdown spectroscopy (LIBS) for particulate matter in diesel exhaust is presented. Conventionally, scanning mobility particle sizer (SMPS) has been widely used to obtain particle size distribution of the suspended particles. However, real-time analysi...

Laser-Induced Breakdown Spectroscopy

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...

Laser Induced Breakdown Spectroscopy

Esta revisão descreve os aspectos fundamentais, a instrumentação, as aplicações e tendências futuras de uma técnica analítica que se encontra em seu estágio de consolidação e que está em vias de estabelecer o seu nicho entre as técnicas espectrofotométricas modernas.

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...
