Gas cavity gas pressure adjusting device of multifunctional laser-induced breakdown spectrometer

Abstract

The invention discloses a gas cavity gas pressure adjusting device of a multifunctional laser-induced breakdown spectrometer, comprising a laser-induced breakdown spectrometer body, a handheld handle,a base, a main controller, a display panel, a laser lens, a gas outlet pipe, a gas inlet pipe, a gas guide hose, a gas outlet, a gas inlet, a gas pressure buffer tank, a gas cylinder, a gas pressureadjustable meter structure, an impurity-proof filtered gas treatment net structure and a detachable exhaust heat dissipation pipe structure, wherein the lower right side of the laser-induced breakdownspectrometer body is connected with the base, and the main controller and the display panel are longitudinally connected to the left and right walls of the lower right side of the interior of the laser-induced breakdown spectrometer body through screws. Through arrangement of a barometer, a gas release pipe, an adjusting rod, an adjusting bolt, a gas pressure adjusting plug, a buffer spring and ahandheld cap, gas pressure adjustment is facilitated, detection operation is facilitated, and adjustment convenience is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of spectrum detection equipment, and in particular relates to an air cavity pressure regulating device of a multifunctional laser-induced breakdown spectrometer. Background technique [0002] The handheld laser-induced breakdown spectrometer includes a laser excitation part and a spectral analysis part. Its working principle is to use a laser to convert a small part of the material on the surface of the object to be measured into a plasma state, and then use a light collector to collect the emitted light from the material in the plasma state. The light, and further use the spectral analysis part to perform spectral analysis on the collected light to determine the composition of the analyte. [0003] At present, when the handheld laser-induced breakdown spectrometer detects substances, it usually needs to use inert gas to protect the detected area, so as to avoid the chemical reaction of the detected substanc...
