X-ray Analyzers

Disadvantages of the XRF:

▪ It is not suitable for analysing very light elements, such as, hydrogen, helium and lithium.

▪ It is not as sensitive as some other techniques, such as, neutron activation analysis (NAA)

and inductive couple plasma (ICP). The detection limit varies according to elements

(depend on atomic number).
