Flame atomic fluorescence spectrometry is to directly introduce the solution to be measured into a transmission chamber through pneumatic atomization, mix it with gas in the transmission chamber to form an aerosol, and transport it to the array flame convergence atomizer to atomize the element to be measured. The atomized atoms are excited by a high-intensity characteristic sharp line light source (double cathode hollow cathode lamp), causing the atoms to be measured to achieve an energy level transition, and release atomic fluorescence during the deactivation process. The intensity of the fluorescence signal of the atoms to be measured is related to its concentration. Proportional to this, this serves as the quantitative basis for the element to be measured.
