Basic principles of atomic fluorescence spectrometer

Atomic fluorescence spectrometer is an instrument developed specifically for testing trace amounts of gold in geological exploration systems. Can replace ICP-MS and be used for the determination of gold in primary ore and tailings, gold loaded carbon and analytical carbon, analytical noble and poor solutions, and cyanide leaching solutions in gold mines. At the same time, it also meets the testing requirements of the geological metallurgical industry for trace amounts of gold less than 0.1 ppb.
The basic principle of an atomic fluorescence spectrometer is that a liquid sample is atomized by an efficiency atomizer to form an aerosol. The aerosol is thoroughly mixed with gas in a pre mixing atomization chamber, and then the sample entering the flame evaporates, melts, and decomposes into ground state atoms through the heat of combustion. The ground state atoms are excited to the energy state by a hollow cathode lamp, and the atoms in the energy state are unstable. During the de excitation process, they emit atomic fluorescence in the form of light radiation. The intensity of atomic fluorescence is directly proportional to the content of the measured element in the sample, thus determining the gold content in the sample.
