Abstract

Theoretical consideration concerning some possibilities for the elimination of matrix effects in non-dispersive X-ray fluorescence and absorption analysis are discussed. The theoretical treatment is concerned with the following methods:
  1. (a)

    double-channel absorption edge analysis,

     
  2. (b)

    concentration increase and dilution method in fluorescence analysis,

     
  3. (c)

    fluorescence-absorption method,

     
  4. (d)

    emission-transmission method,

     
  5. (e)

    fluorescence-Compton scattering method,

     
  6. (f)

    method of multicomponent analysis.

     

On the basis of the derived formulas, nomographic methods of interpretation of the data are given. Using these methods it is possible to determine unambiguously the concentration of the relevant element. The formulas are also convenient for numerical interpretation. The introduction of the concept of “generalized sensitivity” allows the comparison of various radiometric methods.
