Method and apparatus for in-process liquid analysis by laser induced plasma spectroscopy

摘要

A method and apparatus for spectrochemical Analysis of Fluid, including Molten materials using Laser Induced Breakdown Spectroscopy.The Apparatus preferably comprises a high power laser driven Flow on the surface of a Liquid Flowing In a measuring CellAnd a mounting Detection using an optical Spectrometer, which receives, analyzes and detects Radiation emitted by the plasma High Temperature activated in this way.The Measuring cell and a Pump optional, provide a constant Flow of Fluid, thus allowing the laser to take samples of a Cool Surface not alteredRepresentative of fluid volume, and at the same time ensuring that bubbles and waves formed in the liquid are removed from the focal Volume.The gas (usually) blown over the Fluid prevents the material ejected from the aerosol and is sensitive to the incident Energy, interact with the subsequent laser pulses andThat ACCUMULATE in Optical Devices.
