Liquid analysis equipment in laser induced plasma spectral analysis process

摘要

These include: (a) a laser pulse at a specific repetition rate and a specific beam path; and (b) an optimized device to guide the laser pulse to the position of the liquid surface, And produce a plasma, which can emit the element radiation corresponding to the liquid components; (c) a measuring device, which can detect the element radiation emitted on the detection track, including optical window, spectrometer, spectrometer and spectrophotometer, And a data processor that determines the concentration of a default element;(d) A gas flow generator to prevent liquid discharged due to laser pulse accident from accumulating in grating (c) window or laser beam and detection path; (e) Flow unit assembly, including liquid surface level and flow speed control device. In addition, it refers to the laser-induced laser plasma spectral analysis method for liquid and molten materials, using this device.
