Cleaning device for flame cone in atomic absorption spectrometer

Abstract

A cleaning device for a flame cone in an atomic absorption spectrometer, including a cylinder. A flame cone is fixed on the inner wall of the cylinder. A first electric telescopic rod, a telescopic shaft, and a motor are installed on the inner wall of the bottom of the cylinder. The first electric telescopic rod and the motor are installed Located on the left and right sides of the telescopic shaft respectively. The present invention uses a pumping device to pump the cleaning agent into the cylinder while causing the annular piston compression spring to move downward, thereby making the pressure in the cylinder greater, thereby aligning the second through hole with the third through hole next time. When the cleaning agent in the cylinder is sprayed out from the water spray hole, there is a certain distance between the cleaning layer and the inner wall of the flame cone, so that the cleaning agent affects the inner wall of the flame cone. It achieves a stronger flushing and cleaning effect, and at the same time makes the rectangular plate swing up and down quickly to slap the inner wall of the flame cone, thereby enhancing the cleaning effect, saving time and effort, and facilitating regular maintenance and maintenance of the flame cone.

Description

technical field [0001] The invention belongs to the field of cleaning devices for flame cones, in particular to a cleaning device for flame cones in atomic absorption spectrometers. Background technique [0002] The flame cone is a built-in part of the atomic absorption spectrometer, also known as the combustion head. The atomic absorption spectrometer is also called the atomic absorption spectrophotometer. The analyte in the sample passes through the flame cone under the flame, decomposes to produce atomic vapor, the ground state atoms of the element to be measured in the steam are absorbed, and the content of the element to be measured in the sample can be obtained from the degree of weakening of the intensity of the radiated light wave. If the atom is ionized Insufficient, so that the number of atoms in the ground state decreases, the absorbance decreases, and the measured data is inaccurate.

[0002] The flame cone is a built-in part of the atomic absorption spectrometer, also known as the combustion head. The atomic absorption spectrometer is also called the atomic absorption spectrophotometer. The analyte in the sample passes through the flame cone under the flame, decomposes to produce atomic vapor, and the ground state atoms of the element to be measured in the steam are absorbed, and the content of the element to be measured in the sample can be obtained from the degree of weakening of the intensity of the radiated light wave. If the atom is ionized Insufficient, so that the number of atoms in the ground state decreases, the absorbance decreases, and the measured data is inaccurate. The maintenance and maintenance of the flame cone is an important part of instrument maintenance and maintenance. The inner wall of the flame cone needs to be cleaned regularly to prevent it from working normally. At the same time, the inner wall of the flame cone has high requirements for cleaning conditions. Manual scrubbing is too time-consuming and labor-intensive, and other scrubbing methods are not thorough.
