White cell type flame atomizer

Abstract

The invention discloses a white cell type flame atomizer which comprises three concave surface reflectors M1, M2 and M3 with the same focal distance, wherein the concave surface reflectors M1 and M2 are completely same in size and are fixed at one end of a full titanium optical table in parallel, the concave surface reflector M3 is fixed at the other end of the full titanium optical table, the concave surfaces of the concave surface reflectors M1 and M2 are opposite to the concave surface of the concave surface reflector M3, the distance between the concave surface reflectors M1 and M2 and the concave surface reflector M3 is equal to the radius of curvature of the concave surface reflector with the focal distance, a full titanium burning sheet is fixed on the full titanium optical table between the concave surface reflectors M1 and M2 and the concave surface reflector M3, and the full titanium optical table is welded on a full titanium burning seat. According to the invention, a light source is reflected for multiple times by the three concave surface reflectors and goes through 12 linear flames, so that the utilization rate of the light is increased, and the flame atomizer is more miniaturized.

Description

technical field [0001] The invention relates to a White pool flame atomizer, which is mainly used in an atomic absorption flame atomization system. Background technique [0002] The atomic absorption spectrometer is an analytical instrument that determines the content of substances in a sample according to the Lambert-Beer law. It is mainly composed of a light source, an atomizer, a monochromator, a detector, etc., and the light source is an important part of the atomic absorption spectrometer. It Its role is to emit the characteristic resonant radiation of the measured element, and its performance index directly affects the detection limit, precision and stability of the analysis. The function of the atomizer is to provide energy to make the sample go through processes such as drying, melting, evaporation and dissociation to produce a large number of free atoms in the ground state and a small amount of atoms in the excited state. The incident light beam generated by the...

Problems solved by technology

[0003] Atomizers are divided into flame atomizers and non-flame atomizers. Atomization of samples with flames is currently a widely used method. Commonly used burners include single-slit and triple-slit burners. The most commonly used is single-slit Slit burner, the length of the burner is about 120mm, the flame absorption path is generally 100mm, and the light path of the nitrous oxide burner is about 5mm. lower
