Special sweeper for graphite cone of atomic absorption spectrometer

Abstract

The invention relates to a special sweeper for a graphite cone of an atomic absorption spectrometer, and the sweeper comprises an imaging handle, an image receiving assembly, a purging cylinder and ascrubbing assembly; the imaging handle comprises an observation cylinder, a polarizing cylinder and a T-shaped connecting cylinder; the image receiving assembly comprises a view finding cylinder, a view finding mirror and an illuminating lamp; the imaging handle is connected with the other three parts through the connecting flange and the bolts, the pollution condition in the graphite cone is observed through the image receiving assembly, the necessary purging and wiping are conducted according to the pollution condition, and therefore the purpose of accurately sweeping the interior of the graphite cone is achieved. The graphite cone cleaning device integrates the functions of observing the pollution condition in the graphite cone, purging internal floating dust, scrubbing the graphite cone and the like, a convenient and reliable cleaning tool is provided for daily maintenance work of the graphite cone, the service life of the graphite cone can be prolonged, the replacement frequency is reduced, and the cost is saved; the maintenance time can be saved, and the working efficiency is improved; the incomplete cleaning can be avoided, and the detection accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of optical reflection imaging amplification, in particular to a special cleaner for graphite cones of atomic absorption spectrometers. Background technique [0002] The atomic absorption spectrometer is composed of a light source, an atomization system, a spectroscopic system and a detection system. The instrument radiates light with characteristic spectral lines of the element to be measured from the light source. When it passes through the sample vapor, it is absorbed by the ground state atoms of the element to be measured in the vapor. The degree to which the radiation characteristic line light is weakened is used to determine the content of the element to be measured in the sample. The sensitivity, accuracy and simplicity of the atomic absorption spectrometer have been widely used in metallurgy, geology, mining, petroleum, light industry, agriculture, Major and trace element analysis in medicine, sanitat...

AI Technical Summary

Problems solved by technology

Among them, the graphite furnace part of the atomic absorption spectrometer is the main component of the detection of trace substance content. During daily use, some detection parts need to be maintained. If the maintenance is not timely, it will seriously affect the detection performance of the instrument and the accuracy of the detection results. As the core component of the graphite furnace detection method, the graphite cone is the carrying reaction environment for the atomization and ashing of the sample. If the maintenance is not in place, it will cause pollution and affect the test results. In severe cases, its service life will be shortened. Replacement The new graphite cone is not only costly but also time-consuming. At present, there is no stable and fast tool for cleaning and maintaining the graphite cone. At the same time, when the instrument is in use, people cannot directly observe the pollution inside the graphite cone. The daily maintenance process is extremely difficult. Inconvenient and poor maintenance effect, therefore, those skilled in the art urgently need to overcome the above technical problems
