Abstract

The invention discloses a water-carrying flow atomic fluorescence analysis device for analytical chemistry and an innovative analysis method, and relates to the field of water-carrying flow atomic fluorescence analysis. The water-carrying flow atomic fluorescence analysis device comprises an analyzer, the bottom of the analyzer is fixedly connected with a bottom plate, a limiting groove is formed in the upper wall of the bottom plate, and three clamping grooves are formed in the outer wall of the bottom plate at equal intervals; and clamping pins are rotationally connected to the middle parts of the three clamping grooves. Through the arrangement of the driving gear and the driven elliptical gear, when the inner walls of the three lamps face inwards synchronously and form a triangle, the lamps are excited to emit light, lamplight is fully irradiated into a reagent bottle, the three light sources are concentrated in the reagent bottle at the same time, the fluorescence brightness is improved, the three light sources are arranged in the triangle shape, scattering of light is prevented to a certain extent, and the practicability is improved; the fluorescence intensity contrast ratio is greatly increased through the setting of the step 3, the operation method is simple and convenient to operate, the adopted chemical reagent is low in cost, and the imaging effect of further imaging of atomic fluorescence is guaranteed.

Description

technical field [0001] The invention relates to the technical field of water-carrying atomic fluorescence analysis, in particular to a water-carrying atomic fluorescence analysis device and an innovative analysis method for analytical chemistry. Background technique [0002] The substance is excited after absorbing electromagnetic radiation, the excited atoms or molecules are deactivated by radiation, and then emit radiation with the same or different wavelength from the excitation radiation. When the excitation light source stops irradiating the sample, the re-emission process stops immediately, and this re-emission light is called fluorescence; if the re-emission process continues for a period of time after the excitation light source stops irradiating the sample, this re-emission light is called fluorescence. for phosphorescence. Both fluorescence and phosphorescence are photoluminescence, because atomic fluorescence spectroscopy has a lower detection limit, high sensiti...
