The principle and properties of the atomic fluorescence photometer

Atomic fluorescence analyzers are divided into non-dispersive atomic fluorescence analyzers and disperse atomic fluorescence analyzers. The structures of these two types of instruments are basically similar, and the difference lies in the monochromator part, i. H. whether the generated fluorescence should be split.

Operating principle of the atomic fluorescence photometerYWtTextile Testing Instruments, Testing Equipment Manufacturer


Reducing the elements to be analyzed in the sample solution to volatile covalent gaseous hydrides (or atomic vapors) and then using a carrier gas introduced into the nebulizer and atomized to ground state atoms in the argon-hydrogen flame.

The atoms in the ground state absorb the energy of the light source and go into an excited state. During the deactivation process, the excited-state atoms give off the absorbed energy in the form of fluorescence. The strength of the fluorescence signal depends on the sample. The salary ofAnalyte element in the sample has a linear relationship, so the content of the analyte element in the sample can be determined by measuring the fluorescence intensity.
