[0015] It should be noted that the embodiments and features of the embodiments in the present application can be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0016] It should be noted that the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, the singular form can include the plural form unless the context clearly indicates otherwise, and it should also be understood that the terms "comprise" and / or "include" as used in the specification indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0017] Referring to Figure 1 As shown in the drawings, the present application provides a burner of an atomic absorption spectrometer, which comprises a spray chamber 1 for receiving fuel and a burner 2 located on the spray chamber 1. The end of the spray chamber 1 away from the burner 2 is respectively provided with a waste liquid outlet 3, an atomizer interface and a fuel interface 5. The atomizer interface is arranged at the end of the spray chamber 1, and the waste liquid outlet 3 and the fuel interface 5 are symmetrically arranged on the upper and lower sides of the atomizer interface. In addition, the flame collision ball 6 is arranged at the position close to the atomizer interface inside the spray chamber 1.

[0018] In use, the atomizer is connected via the atomizer interface, fuel is injected through the fuel interface 5 and the burner 2 is ignited. During this process, the impactor ball mixes the fuel gas and the combustion gas and ignites it, producing a stable flame for sample atomization. When the sample solution is injected into the flame, the elements in the sample are atomized and excited, emitting light at specific wavelengths. During the optimization of the flame atomic absorption system, adjusting the position of the impactor ball can control the sensitivity noise, interference effects, calibration linearity and working range, and reduce the possibility of burner 2 blockage. In the atomic absorption atomizer chamber, a suitable atomizer chamber design can minimize carbon deposition and reduce the possibility of burner 2 blockage and volatile interference. The waste liquid produced during the flame combustion process can be discharged from the device through the waste liquid outlet 3.

[0019] As a preferred, the fuel is a fuel gas.

[0020] As a preferred, the flame impactor ball 6 includes a standard glass impactor ball or an inert PTFE ball. In actual use, for samples containing high concentrations of dissolved solids or hydrofluoric acid, an inert PTFE ball can be used because these samples can corrode or chemically attack the standard glass impactor ball.

[0021] The above is only a preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
