Non-dispersive atomic fluorescence excitation light source impurity detection device

The invention discloses a non-dispersive atomic fluorescence excitation light source impurity detection device. The device comprises a dark box casing, a light source fixing bracket, a light source electric control device, a lens, an attenuation window, an ultraviolet spectrum detection component and a host processor. According to the invention, no stray light enters after the dark box casing is closed, a detected light source is fixed by an installation structure, appropriate adjustment can be carried out on a detected lamp through a screw and a pressing piece, the lens and the attenuation window are used in a matched mode according to different intensity of the light source, detection data is processed by a computer processor, and test results such that whether the light source has impurities or not and impurity elements are confirmed and the like can be given out directly. The project research results are that the non-dispersive atomic fluorescence excitation light source impurity detection device provides an excitation light source screening basis for manufacturers and users of a non-dispersive atomic fluorescence photometer, can provide an improvement direction for manufacturing enterprises of a non-dispersive atomic fluorescence excitation light source, and has great significance for analyzing a measurement result of a non-dispersive atomic fluorescence method.
