Abstract

The invention discloses an atomic fluorescence spectrophotometer, aiming at solving the problem in the prior art that an excitation light source drift correction function is not complete. The atomic fluorescence spectrophotometer comprises an excitation light source, a first optical lens, an atomizer, a light receiver, a first photoelectric detector and a second photoelectric detector, wherein the excitation light source, the first optical lens and the atomizer are arranged on the same optical axis; the first optical lens is located between the excitation light source and the atomizer; a characteristic spectrum emitted by the excitation light source is focused on the atomizer through the first optical lens; atomic fluorescence generated by the atomizer is received by the second photoelectric detector; the light receiver is used for receiving the characteristic spectrum emitted by the excitation light source and transmitting the characteristic spectrum to the first photoelectric detector.

Description

technical field [0001] The invention relates to the field of optical systems, in particular to an atomic fluorescence photometer. Background technique [0002] Atomic fluorescence spectroscopy is a qualitative and quantitative analysis of substances using the wavelength and intensity of atomic fluorescence spectral lines. It has the advantages of simple equipment, high sensitivity, less spectral interference, wide linear range of the working curve, and multi-element determination. It has been widely used in various fields such as geology, metallurgy, petroleum, biomedicine, geochemistry, materials and environmental science. The common excitation light source correction is that the photodetector receives the energy of the excitation light source and converges on the atomizer through the lens, and cannot directly detect the energy of the excitation light source, so its excitation light source drift correction function is not comprehensive.
