A movable metal slit burner for atomic absorption spectrometer

Abstract

The invention is a movable metal slit burner for an atomic absorption spectrometer, a movable metal slit burner for an atomic absorption spectrometer, comprising a panel substrate, a section of chute is arranged on the surface of the panel substrate, and the chute A slider is slidably arranged, and a burner port platform is provided at one end of the chute, and a movable splint and a fixed splint are respectively arranged on the burner port platform, and a combustion slit is formed between the movable splint and the fixed splint. The movable splint is fixedly connected to the slider, the fixed splint is fixedly connected to the panel substrate, and a pull rod is fixedly connected to the side of the movable splint, and one end of the pull rod is connected with a handle that can be pulled. By adopting the technical solution of the present invention, the general indicators such as the parallelism and linear range of the metal seam of the burner fully meet the clinical test standards, and it has the characteristics of easy disassembly and cleaning, which is beneficial to the maintenance and maintenance of experimental instruments.

Description

technical field [0001] The invention relates to the technical improvement of instruments and equipment, in particular to the structural improvement of the BH5100 atomic absorption spectrometer burner. Background technique [0002] The determination of trace elements by atomic absorption spectrometry has the advantages of simple structure, easy operation, high sensitivity, stable performance, less time-consuming, minimal blood consumption, and low price, and is widely used in clinical practice. The BH5100 absorption spectrometer commonly used in clinical practice is used for the detection of copper, iron, zinc, calcium, magnesium and other five elements in blood. The measured elements in the sample are converted into gaseous ground state atoms, which absorb light and perform content analysis. During the use of the instrument, it was found that after a certain amount of blood samples were taken, the slit burner was prone to fouling. If it was not cleaned in time, the flame wo...

AI Technical Summary

Problems solved by technology

During the use of the instrument, it was found that after a certain amount of blood samples were taken, the slit burner was prone to fouling. If it was not cleaned in time, the flame would split and the test results would be unstable, making interpretation difficult. The burner cannot be disassembled, and it is inconvenient to clean. After daily use, it can only be repeatedly rinsed against the seam with running water or scraped off the seam residue with a blade, and the internal scale cannot be cleaned.

[0003] like figure 1 As shown, the slit burner of the BH5100 absorption spectrometer commonly used in clinical practice mainly includes a panel base 1 and a metal slit 2. The panel base 1 is an integrated structure, and the metal slit 2 is directly processed on the panel base 1. Therefore, its panel substrate cannot be disassembled, the seam is small, the surface of the seam is difficult to clean, and the rinse is not clean. It will rust after a long time, and the inside of the seam is more difficult to rinse
