Advantages and Limitations of Atomic Fluorescence

Several advantages and disadvantages to the use of atomic fluorescence are apparent from the theoretical development given in the preceding section. Some of the advantages include the following. 

Increasing the radiation intensity should linearly increase the fluorescence intensity 7.  

A long-path sample cell should increase the fluorescence intensity Ip if suitable means of collecting the fluorescence signal is available. 

Fluorescence intensity, as a function of concentration of fluorescing atoms, is linear at low concentration levels, making the procedure especially useful for trace element determinations. 

Fluorescence spectra are simple, so high resolution spectrometers are unnecessary.
