Description

Technical Field

[0001] The utility model belongs to the technical field of optical analysis equipment, and particularly relates to an atomic fluorescence instrument capable of automatically correcting light source drift. Background Art

[0002] Atomic fluorescence analyzer is a spectral analysis instrument for quantitative analysis of various heavy metal elements. It uses the fluorescence effect of atoms to perform quantitative analysis of various elements. Atomic fluorescence analyzer is generally composed of atomization system, optical system, excitation light source, photoelectric detection and control system, data processing system and other parts.

[0039] The third step: At this time, the light direction of the element lamp 16 is fixed, and the atomic fluorescence instrument body 1 is in a horizontal state. Since the atomic fluorescence instrument body 1 requires the light direction of the element lamp 16 to be projected on three different scales on the dimmer 9 for different test samples, the drive motor 2 is started through the operation panel 28 to drive the first bevel gear 3 and the second bevel gear 4 to rotate, thereby driving the screw 6 to rotate and push the inner corrugated tube 7 out, so that the dimmer 9 can be raised and lowered to the scale required by the element lamp 16, thereby completing the work of automatically correcting the light source drift.
